Product features

The pneumatic cast steel ball valve is mainly composed of floating ball valve, pneumatic actuator and related accessories. The valve body is made of Silica Sol precision casting and high platform design. The ball valve can be opened and closed by compressed air as the power source. It can control the flow rate of all kinds of valves such as 20mA, pneumatic positioner and so on.
Features of pneumatic cast steel ball valve:
 
1. The pneumatic cast steel ball valve adopts floating through structure. The valve body channel and connecting pipe diameter are equal and form a diameter, and the medium can flow through almost without loss;
2. Q641f-16c pneumatic ball valve takes purified dry compressed air as power source, which can be used as switch cut-off function and flow regulation function. It has the characteristics of simple operation and good reliability.
3. The actuator of pneumatic carbon steel ball valve is connected with the ball valve without bracket and connecting shaft. By selecting different valve body and seat material, it can be used in different working conditions.
4. Pneumatic floating ball valve actuator can be equipped with live signal feedback indication and various accessories to realize automatic operation (explosion-proof optional).

Executive structure of pneumatic cast steel ball valve:
Double action: switch action should be driven by air source, ventilation on and off, air source failure to maintain the current position
Single action: only the on / off action is driven by air source, while the off / on action is reset by spring.
Single acting normally closed type: ventilation on and off, air source failure closing
Single acting normally open type: ventilation off, air cut on, air source fault on
Optional accessories: reversing solenoid valve, limit switch, air filter pressure reducing valve, electric positioner, hand wheel mechanism, and retaining valve
Additional functions: optional explosion-proof and manual device (open and close the valve manually in case of failure)
