Pneumatic Pulverized Coal Ball Valve
【Product Overview】
The Q647F-16C Pneumatic Trunnion Mounted Ball Valve is a high-performance automated valve designed for medium to high pressure pipelines carrying oil, gas, steam, and solid-particle media. Constructed with a WCB carbon steel body and SS304 internal components, it ensures both strength and corrosion resistance.
The trunnion-mounted structure provides stable sealing even under high pressure by reducing seat deformation. Operated by a pneumatic actuator, this valve is ideal for remote control and high-frequency on/off operations in industrial automation systems.
