Description
The valves type IRC are screw-in, direct-acting, poppet-type, in-line check valves. They have a
compact shape which makes them suitable for use in manifolds.
They allow oil passage from “1” to “2” and stop it in the opposite direction. The poppet and seat
are hardened and ground to guarantee seal and service life.
External surfaces are oxide burnished to increase the protection degree to corrosion. All the
valves parts are made in high strength alloy steel. Cavity is gas (Bsp).
Main use is as blocking or pressure holding device.
