Explosion proof electric motorized control valve

Explosion proof electric motorized control valve Product introduction

　Explosion proof electric motorized control valve manufacturer, factory and supplier. Explosion proof electric motorized control valve is used for explosive environment such as explosive gas,coal and others, which is excellent in performance, and is a high-quality base type electric control valve product. Explosion proof electric motorized control valve is suitable for production process control systems for explosive media process conditions,which has reliable operating characteristics, small seat leakage, coarse flow characteristics, wide adjustable range, compact structure and smooth flow path. Explosion proof electric motorized control valve has good performance and stable operation , and can meet the user’s control needs in a wide range of applications.

Explosion proof electric motorized control valve features:

Explosion proof electric motorized control valve consists of 3810L or PSL series explosive proof electronic electric actuator and asingle-seat ( sleeve ) regulating valve. The actuator has an integrated structure with built-in electronic controller modules, eliminating the need for additional servo amplifiers . It has high precision and is easy to install The characteristics of Electric motorized water control valve is as follows:

Adopting balanced valve core, the unbalanced force is small, the pressure difference is allowed to be large, and the operation is stable
The large guide surface of the spool improves the oscillation caused by eddy currents and shocks and reduces damage
The noise of the ordinary single and double seat Electric motorized water control valve valve is reduced by about 10dB
Simple structure, convenient assembly, and disassembly
