  •  Pneumatic Y-type three way ball valve

Product features

Q942f / h pneumatic Y-type three-way ball valve, as the name implies, adopts the form of Y-type flow channel. The valve seat is a three-sided valve seat, which has two valve body structure forms of 120 ° and 135 ° to each other. According to the needs, it can realize the switching of medium flow direction. The installation forms of pneumatic Y-type three-way ball valve are various, and different shapes can be selected according to the pipeline layout. The flow channel is flat, the fluid resistance is small, and the flow capacity is strong. The medium will not stay in the flow channel. The pipeline can be switched smoothly and well without secondary pollution.

Application of pneumatic Y-type three-way ball valve:
 
According to the different working conditions, the pneumatic Y-type three-way ball valve and valve seat can be sealed with soft sealing, spray welding nickel base alloy (hardness greater than HRC60), supersonic tungsten cobalt alloy coating (hardness greater than HRC70) and special hard materials. It is suitable for various harsh working conditions. The soft sealing is applicable to the working conditions below 200 ℃, the hard sealing carbon steel is not more than 425 ℃, and the stainless steel is not more than 450 ℃.
