Product Details

Ideal for installation in tight spaces, this piston spring check valve can provide backflow protection for a variety of applications. Model has an embedded O-ring that seals on the seat. Pressure in the direction of flow moves the piston and seal off the seat and exposes the cross holes in the piston. Valve is designed to provide a positive seal at very low back pressure or slight vacuum.
