HCB High Temperature Globe Control Valve, WCB, WC6, WC9

Pneumatic high temperature control valve consists of multi-spring pneumatic diaphragm actuator and low flow resistance high temperature control valve body. The body flow channel of pneumatic high temperature globe control valve  is S streamline type. It has the advantages of compact structure,light weight,sensitive action,small pressure drop loss,large valve capacity,accurate flow characteristics and convenient maintenance.The pneumatic high-temperature control valve is especially suitable for occasions where the leakage is small, the pressure difference between the valve is small and the temperature is high.

 The Features of High Temperature Globe Control Valve:

1. The body flow funnel is S streamline type. Her benefits of compact structure, lightweight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics and convenient maintenance.

2. Balanced and unbalanced valve plugs have high cut-off sealing performance within the entire flow and characteristics range

3. Metal seals and soft seals have a similar flow coefficient

4. Special surface management of the valve inner parts--polishing, nitriding and Stellite resurfacing welding to increase the service existence from the controlling valve, the work surface is much more reliable

5. Adjustable ratio would be to 50:1,and 100:1 may also be customized

6. Use high quality non-asbestos seal or bellows seal

7. Multi-spring pneumatic actuator can realize direct acting and reverse acting. The spring range could be adjusted without adding other areas. The direct acting actuator can realize the environment-to-close operation, and also the reverse acting actuator can realize the environment-to-open operation.
