2 Pcs Pneumatic cut off O type ball valve

Short Description:

Pneumatic stainless steel ball valve material is on base of different material for corrosive medium,Pneumatic stainless steel ball valve is one type of ball valve assembly which is mounted with pneumatic actuator, achieving in the purpose of automatic control and remote control on the ball valve action.

There are two types of pneumatic actuators mounted with the Pneumatic stainless steel ball valve, one type is single action pneumatic actuator (which is also called spring return pneumatic actuator); the other type is double action pneumatic actuator. Normally, the clients select the spring return pneumatic actuator, because this type of pneumatic actuator needs only one air supply.
