Pneumatic Splint ball valve
详情介绍
product description:
One,Pneumatic ultra-thin overview of pinch ball valves
Pneumatic clamps the ball valve USES the bracket and the actuator connection, has the structure compact volume small, the weight light, the friction force small, the return difference small, the movement is stable and reliable and so on the merit.
Pneumatic double piston pinion and rack actuators and ultra-short flange distance from the combination of the ball valve, the body part with the "1" electric ball valve body.
Pneumatic piston actuators are divided into spring and non-spring type two. When the valve is required to be fully open or closed under fault, it is equipped with a spring type (depending on the spring to restore tension). When the valve is required to be kept in position under fault, it is equipped with a spring-free type. It is mainly composed of cylinder block, spring, piston, piston rod, front and rear cylinder head, rack, output shaft and other parts. For two - valve, solenoid valve and travel switch; For proportional control valve, need to be equipped with positioner.
