    Why Purchase Control Valve From BCST

    Control Valve -FAQ

    1.What is Control Valve Actuator?

    An actuator is an assembly fitted to the control valve to supply energy for the transfer of fluid elements, the plug, ball valve, or vane. The control valve operation consists of positioning those elements relative to the desk-bound seat of the valve. Therefore, control valves need actuators to operate.

    The valve actuator performs a critical function. First, circulate the elements to a system required with the aid of using the control valve and default positioning at the same time as there’s no pressure energy available. Next, the actuator accepts a sign from the control device and, in response, moves the valve to a completely open or completely-closed or extra excellent closed function.

    There are three actuators for control valves; pneumatic, electrical, and hydraulic.

    Pneumatic actuators 

    Pneumatic actuators are the maximum substantially used approach of actuation. They can deliver crucial forces with an adequate journey speed for optimum programs. They provide fail-steady responses to pressure electricity loss by including spring devices in the design. They are inherently stable towards explosion hazards, and widespread strategies include a piston, diaphragm, or rotary vane types.


    • High pressure and pace of motion.
    • High durability.
    • Reliability
    • Safe technology.
    • Inexpensive.


    Electric actuator

    The electric actuator uses a motorized electric motor and a gears reduction power to transport the valve into linear or rotary excursions. They may be used for on-off applications for huge isolating valves. They additionally offer non-stop positioning control with the aid of using providing position feedback to a controller imparting variable pace reversible power action. They are broadly carried out in the energy generation industry, water supply/treatment plants, pharmaceutical, etc.


    • Accurate control and positioning.
    • Able to prevent at any point of the stroke.
    • Easy to set acceleration and deceleration.
    • No outside sensors.
    • Low working costs.
    • Excellent performance at a high speed.
    • Maintenance friendly.
    • Low hazard of contamination.

    Hydraulic actuators

    Hydraulic actuators use liquid pressure to transport the valve mechanism. Almost all hydraulics actuators use a piston in preference to a diaphragm to transform fluid pressure into mechanical pressure. Hydraulic actuators generate significant mechanical power because they’re utilized in huge isolating valves on gas pipelines. In addition, they showcase very strong positioning because of the non-compressibility of hydraulic oil. Some actuator designs integrate hydraulic and electric powered strength.  


    • Infinitely variable control of equipment ratio in a huge variety and a possibility to create the big reduction ratio.
    • Small precise weight.
    • Simple and reliable protection of the engines from overloads.
    • Slight sluggishness of the rotating parts.
    • The simplicity of transformation of rotary motion into reciprocating one.
    • The possibility of positioning a hydraulic device on removal from a power source.
