5PK Plastic 6mm Barb Ball Cone Vent Spring Check Valve One Way Inline PP housing
When the fluid pressure at the inlet end is lower than the relief value, it is in a sealed state; when the product is stationary, it is in a sealed state. When the fluid pressure at the inlet end is higher than the relief value, it pushes the steel ball forward, and the fluid flows out around the steel ball, thereby achieving safe pressure relief.
