Pneumatic Forged Steel Trunnion‑Mounted Ball Valve is a quarter‑turn ball valve driven by a pneumatic actuator with forged‑steel body and trunnion‑mounted ball construction. The pneumatic actuator rotates the valve stem by 90° to turn the ball for fast on‑off operation and reliable shut‑off of pipeline media.
Compared with floating ball valves, trunnion‑mounted ball valves adopt a ball supported by upper and lower trunnion bearings. The ball is carried by fixed bearings, which effectively reduces operating torque on the seats. They are particularly suitable for large‑bore, high‑pressure and frequent‑cycling working conditions.
The forged‑steel valve body delivers high mechanical strength and pressure‑withstanding capacity. Soft‑seat or metal hard‑seat can be configured for various service requirements. Optional features include anti‑static design, fire‑safe construction, double block and bleed (DBB), and emergency grease injection for seat sealing.
Working Principle of Pneumatic Forged Steel Trunnion‑Mounted Ball Valve:
Control signal → Solenoid Valve / Positioner → Compressed Air → Pneumatic Actuator → Valve Stem Rotation → Trunnion‑Mounted Ball Rotation → Valve Open / Close
Pneumatic Shut‑off Ball Valve are 0‑90° rotary valves. They utilize pneumatic actuators to convert compressed air into rotary motion, delivering fast and reliable valve opening and closing for industrial process control.
According to specific application requirements, pneumatic ball valves can be equipped with solenoid valves, limit switches, position feedback devices, air filter‑regulators, valve positioners and other pneumatic instrument accessories to realize automatic valve control and remote monitoring functions.
Many factors shall be considered when selecting a pneumatic ball valve, including valve size, pressure rating, operating temperature, process medium, flow rate, body material, seat material, actuator type and control mode.
If you are looking for a qualified manufacturer or supplier of pneumatic ball valves, please contact our technical team and provide your operating conditions. Our valve engineers will recommend suitable pneumatic ball valves, actuators and control accessories based on your specific application requirements. （Unit: mm）
