Description
Pneumatic Quick-Open EQ Linear Cage Guided Globe Control Valve
Pneumatic Quick-Open EQ Linear Cage Guided Globe Control Valve is a high-performance regulating valve suitable for the flashing and cavitation occasions caused by high-pressure difference. The strong sleeve of the cage guided globe control valve protects the valve body from flashing and cavitation. The flow channel of cage guided control valve is an S-shaped streamline, the pressure drop loss is small, the flow rate is large, and the adjustable range is wide. The valve plug has a large guiding area and good shock resistance. The adjustment performance is fully compliant with IEC or GB standards. This cage guided globe control valve is equipped with a multi-spring diaphragm actuator, which has a compact structure and a large output force. Pneumatic Quick-Open EQ Linear Cage Guided Globe Control Valve is widely used in applications requiring high reliability and shut-off performance, low temperature, and high-pressure process line. Due to the wide range of materials and diverse design forms, these valves can be used in various industrial fields (such as chemical, gas, electricity,paper-making, food, metallurgy and mining, etc).
Feature of Pneumatic Quick-Open EQ Linear Cage Guided Globe Control Valve
- The various materials of valve castings and internal parts with various materials can suit special working conditions;
2. It can reduce the noise level, improve the anti-cavitation and anti-flashing performance, and eliminate the blocking flow;
3. The flow coefficient range of cage guided control valve is large, and the adjustable ratio range is large;
4. The optional metal bellows seal can prevent leakage of corrosive and highly toxic medium and pollute the environment;
5. Easy to disassemble and install the trim, and easy to inspect and maintain;
6. It adopts high-quality materials and surface treatment technology (polishing, Stellite alloy, heat treatment, chromium nitride coating), and the cage guided globe control valve has long service life and reliable operation;
7. The direct and reverse acting is realized by the cooperation of the pneumatic film multi-spring actuator, and the spring range (the number of springs is unchanged) can be changed without adding other parts;
8. The operation mode can be pneumatic, electric, and electro-hydraulic linkage;
9. A manual operating mechanism can be installed on the side or top of the actuator.
