Each brass piston check valve incorporates a piston with an embedded O-ring that seals on the seat. Pressure in the flow direction moves the piston and seals off the seat and exposes the cross holes in the piston. The flow arrow on the body will point from inlet to outlet. Check valves have a maximum operating pressure of 500 psi covers a wide range of air and fluid applications. They are a compact design and have a positive seal at very low back pressure or slight vacuum.
