Functional Description
The check valve serves the leak free closure in one
direction and allows flow in the opposite direction. The
poppet design provides leak free closure.
The seat is created directly in the valve housing (1) and
the small ball (2) is pushed by spring (3) through the
thumb ring (4)* onto the seat. The cracking pressure
depends on the spring selected, its preloading and the
pressurized poppet surface area. Four* cracking
pressures are available.
The surface of the valve housing is zinc coated.
