Product Detail

Based on different medium conditions, this pneumatic wafer ball valve is available with PTFE seal and PPL seal, applicable for working temperature below 250℃. When equipped with a valve positioner, it becomes a pneumatic regulating wafer ball valve to adjust the flow rate of pipeline medium. Matched with a solenoid valve, it can realize on-off control of pipeline medium.

Accessory Selection

Standard configuration: AT-type double-acting pneumatic actuator (single-acting type for optional selection). Optional accessories: Solenoid directional valve (AC220V, DC24V, explosion-proof type), limit switch (valve position feedback, explosion-proof type), air filter pressure reducing valve (air source three-piece unit).
