Why Purchase Actuated Valve From BCST
Actuated Valve -FAQ
How many types of actuated valves are there?
Common types of actuated valves are:
- Manual actuated valve
- Actuated butterfly valve
- Pneumatic actuated valve
- Hydraulic actuated valve
- Electric actuated valve
Manual actuated valve:
A manual actuator employs lever wheels or gear to move the valve stem with its specific function. Unlike an automatic valve system, you don’t need support from some electric power source or gas. It is not a suitable valve type while working with any chemical or other toxic material. It needs more effort to control and has smaller capability limits. But if even your operation needs an automatic actuated valve, it’s better to have a manual actuated valve backup. But you cannot handle larger valves manually.
Actuated butterfly valve:
Contrary to many valve systems, Butterfly actuated valves are constructed with a straightforward design. These valves are used in the handle, gear, or switch action. Butterfly Actuated valves are best for preventing wastewater from maintaining a fire shield from gas chains. It is so simple that you have to only one quarter turn to keep the system fully open or closed. These actuated valves are composed of carbon steel or stainless steel.
Features of Butterfly actuated valves:
- This actuated valvecontains an advanced seat design and gives a seal at high, low, or medium pressure.
- This actuated valvecontains an extended neck, which can pass more flow inside the pipeline.
- It contains more strength in high torque systems.
Electric actuated valve:
Electric valve systems are worked with multi and quarter-turn control. These are very reliable solution that automatically rotates. Because of this, there is no need to push air through the valve type manually. Mali turns solutions works for large valve types, and the quarter-turn system is best for small motors. This kind of actuated valve is non-toxic and saves energy as well. You can handle them with a battery.
Pneumatic actuated valve:
These actuated valve types need fluid as a power source. When an electrically actuated valve is unavailable, these valves are the best option for keeping air flow balanced. Air is the source of power in the pneumatic actuated valve. The air pressure moves the piston or diaphragm, creating a straight pressure on the valve’s stem. A pneumatic actuated valve needs a spring to open or close. It contains a compressed air system that gives clean, dry, and compressed air to the pneumatic actuated valve‘s actuator, and in some kind of actuated valve also maintains the air, which is compressed.
Hydraulic actuated valve:
Hydraulic actuated valves are similar to pneumatic actuated valves, as they take power from fluid pressure. It changes the pressure of the fluid into motion. Fluid pressure moves the piston, giving a straight motion to the gate or globe-actuated valves. Many hydraulic actuated valves include opening and closing in case of emergency. You can provide a hydraulic pressure with the help of a hydraulic pressure pump. In some the systems like water pumping plants, the fluid gives hydraulic pressure.
Many pneumatic and hydraulic options use cylinders supported by a mechanism that turns the linear motion into quick gear. Air is produced in the cylinder through quarter-turn motion.
How is Actuated valve different from the control valve?
Actuated valves are different from control valves and many different ways. The operation of a control valve position of the movable valve involves such as the plug, ball, or vane relative to the stationary seat of the valve. However, the purpose of the actuated valve is to accurately locate the valve plug in the position directed by the control signal.
What is the difference between the actuated valve and the automatic valve?
There is not much difference between an actuated and automated valve; when we think about the difference, we can only find one difference. That is semantics. You can handle both the valves by using hydraulic electric or pneumatic actuators, responsible for the opening and closing of both automated and actuated valves. You can use these valves in process plants, wastewater treatment plants, refineries, food plants, and pipelines.
What is the method of control of actuated valves?
The method of control is fundamental in case you want to install a new actuated valve in your system:
There are three kinds of methods for control in actuated valves.
· Rotary motion actuated valves:
This category of the actuated control valve comprises ball actuated valve, Butterfly actuated valve, rotate quarter-turn actuated valve, or many from open to close in actuated control vale.
· Linear motion actuated valves:
This actuated valve comprises gate actuated valve, globe actuated valves, and diaphragm actuated valves; an angle actuated valve contains a sliding stem. It pushes the closure part and closes and opens the valve. The valve’s stem rises during rotation or will be lifted when there is no rotation.
What are the functions of actuated valve?
There are two ways of controlling actuated valve actuators:
- The first one is start/ stop valves
- Throttling or control devices
Start/ stop actuated valves:
Another name for on/ off devices you can also call an isolating device. It regulates actuators’ movement to open and close state.
It gives a motion that you can easily control so that the valve the system will be able to throttle the valve in as required. This type of actuated valve contains a positioner that moves the actuator to the position which is needed.
What are linear actuator specifications in actuated valves?
A linear actuator in actuated valve makes a straight motion. You can use a linear actuator as an external resource for energy, and there are many methods for gaining this kind of movement in an actuated valve. i.e., mechanical, hydraulic, pneumatic, and electric actuated valves are the valves that create a linear motion. Other than hydraulic and pneumatic actuated valve, all other actuated valves produces linear movement by using a motor.
What are performance specifications for linear actuators?
The performance specification involves:
- Valve stem stroke length
- Time of actuation
- Actuator force
- Capacity of load
Valve stem stroke length:
The valve stem stork means that you can use to define the distance coverage needed to actuate the valve from an entirely open to close state completely. It is the actuators that decide the valve stem stroke. Suppose the actuator chooses a stroke that is not more than the actuated valve. Using an actuator with the valve will go to the position of short stroke, and you will not get a CV rating.
Time of actuation:
Actuation time is also significant in actuated valves; it is the time the actuated valve takes to close the straight or linear motion completely.
The actuators should provide proper force to control the pressure inside the system to keep the valve shut by closing.
The capacity of load:
The actuator is an actuated valve that is a tool that controls the static load; the capacity of the static load means that when the device is not in a moving position, then how much load the actuator of the actuated valve can support. And on the other hand, the dynamic load is the capacity of load that an actuator can support when the valve is in working condition.
What are the general specifications of an actuated valve?
General specifications of a valve involve:
- Source of power
- Control signal input
- Diameter of the valve stem
- Number of rotations
- Type of location
Source of power:
When you think about the general specification, you can drive the actuators of actuated valves with the help of electricity or fluid. The electricity needed for actuators depends on the size of actuators large-sized actuators need a three-phased electricity supply, and small actuators need a single phase. You can get a DC supply as an emergency backup, depending on the situation. Fluid-powered or hydraulic actuators have more variations than others, so you should consider the type of fluid, cylinder size, and the pressure of media available when choosing a hydraulic actuated valve.
You should also consider the kind of valve, the appropriate size of the valve, the type of the actuated valve installed, and you should know if the actuated valve is a quarter-turn or multi-turn; you must know about the stem whether it is rising or non-rising. Another thing you should consider is the power that the valve needs; you can calculate the torque only when you know the type of valve. You can get this data from the producer of the valve.
Type of Control signal input:
Three primary control signal types are:
- Milli ampere
You can get applications that use Ac or DC voltage. Signals is a discrete voltage supply (120/240VAC or 12/24 VAC).
Pressure supply means the input pressure you require to get the necessary torque for your system output. The actuated valve producing companies mention the air supply needed for pneumatic actuators and fluid actuated valves for hydraulic actuated valves. The air you need for your pneumatic actuators usually starts from 60 to 100 Psig.
Diameter of valve’s stem:
You can assemble the valve’s diameter of the valve’s stem to lead and pitch the actuated valve‘s stem thread so that you can get the proper size for automation needed for your valve. You can also use it for calculating pressure drop and the torque inside the actuated valve.
The number of rotations:
The number of rotations means the rotation number performed by the actuators of an actuated valve when the stem moves from an open to a completely closed position.
Type of location:
You can get the actuated valves designed for dangerous locations and use them in an atmosphere with combustion-able or flammable fluids. These kinds of actuated valves are particular kinds of tools that you can use in hazardous locations. There are some other actuated valves that you can use in non-hazardous locations. But remember, you should not use an electric actuated valve in outdoor locations. But you can use compressed air actuated valves outside.
What are the advantages of electric actuated valves?
- If you use an Electric actuated valve, you do not need any air or fluid pressure.
- You can use it ultimately when you have low temperature, causing freezing in air supply systems.
- The Electric actuated valve is also able to produce adjustable speed for operation.
- It’s easier for you to handle electric cable than piping system actuators.
Who are the manufacturers of actuated valves?
BCST has mastered the artwork of creating actuated valves in a quick span of 20 years. The organization is one of the biggest producers of actuated valves in China. Thanks to its challenging work, expertise, and dedication, BCST has performed an outsized role in China and received the consideration of maximum nations worldwide. And the evidence is that the organization exports actuated valves to extra than a hundred nations worldwide. The organization gives superb actuated valves to its clients. An actuator of a valve is a full-size part of a mechanical, heating, plumbing, or cooling device. Without an actuated valve, you can’t even believe using your heating, cooling, or plumbing device. It is an exquisite and critical device for opening and near your valve. Without an actuated valve, you may not be able to govern the air stress and water flow. Leaving those valve elements open will create leakage or breakage of pipes inside your air compression device.
