Electric Fixed Ball Valve
Design Features
Pneumatic fixed ball valve adopts a ball structure supported by upper and lower fixed shafts, with low operating torque and stable sealing performance; The valve seat adopts a dual sealing design of elastic pre tightening and medium pressure assistance, achieving bidirectional zero leakage; Equipped with high-performance pneumatic actuators (with integrated locators), supporting fast 90 ° stroke control, and featuring fire-resistant, anti-static, and anti valve stem blowing safety structures.
