pneumatic fixed ball valve overview
q647f pneumatic fixed ball valve produced and sold by woci valve group, pneumatic ball valve, ball valve is a two-way valve, flow unlimited.the middle flange is connected by stud, and the upper and lower valve stem are provided with sliding bearings to reduce friction, and the operation is labor-saving and smooth.under normal circumstances, when the low pressure seating rely on spring pre-tightening force to seat close to the sphere seal, high pressure, the formation of piston effect on the seat, under the effect of upstream medium pressure, make the seat clamp sphere to seal fixed ball valve, pneumatic, pneumatic ball valve, ball valve is widely used in process control system implemented on or off.
