Pneumatic Actuated Forged Steel Flanged Floating Ball Valves

JOEPAI Valve has been a manufacturer of Pneumatic Actuated Forged Steel Flanged Floating Ball Valves for many years. The ball valve is made of forged steel, which, compared to cast steel, has a finer grain, higher mechanical strength, and superior resistance to high pressure and impact, making it suitable for high-temperature and high-pressure conditions. The floating ball moves towards the valve seat under medium pressure, forming a self-tightening seal; the higher the pressure, the tighter the seal, making it particularly suitable for high-pressure pipelines. The pneumatic actuator is driven by compressed air, offering fast opening and closing speeds and enabling remote control and automated operation, suitable for frequent switching or emergency shut-off. It can be equipped with accessories such as solenoid valves, limit switches, and positioners to achieve precise control and signal feedback, and is easily integrated into DCS/PLC systems.

Design Advanges

Pneumatic actuators offer rapid opening and closing, facilitating remote control and automated integration, thus improving system efficiency. Pneumatic drives eliminate the risk of electrical sparks, making them suitable for hazardous environments such as flammable and explosive materials. In case of overload, the actuator typically only stops or vents, posing no risk of damage and ensuring system safety. They can be widely used to control air, water, steam, oil, corrosive media, slurry, and even radioactive media, meeting the needs of complex operating conditions. The two-piece ball valve, with its valve body bolted together in two parts, is easy to disassemble, facilitating thorough cleaning and maintenance of the valve chamber. It is particularly suitable for processes requiring constant pipeline cleanliness or frequent media switching.
