FAQ
1. What is a pneumatic butterfly valve used for?
It is commonly used for automatic shut-off and flow control in water treatment, HVAC, chemical service, utility pipelines and industrial automation systems.
2. What is the difference between a pneumatic butterfly valve and a manual butterfly valve?
A pneumatic butterfly valve uses compressed air to drive the actuator for automatic operation, while a manual butterfly valve is operated by a lever or gear. Pneumatic valves are more suitable for automation and remote control applications.
3. What actuator types are available?
Common actuator options include double acting and spring return pneumatic actuators. The suitable type depends on the control logic and fail-safe requirement of the system.
4. What accessories can be supplied with this valve?
Optional accessories include solenoid valves, limit switch boxes, positioners, air filter regulators and other control components according to project requirements.
5. What media is this valve suitable for?
It is generally suitable for water, air, gas and other general industrial service media. Final material selection should be confirmed according to the actual working condition.
6. Can you provide customized valve body types, materials or control configurations?
Yes. We can provide customized body type, material selection, seat type, actuator specification and accessory configuration according to project requirements.
