Ductile Axial Check Valve with Flanges, PN25, Fig. 39N

Also known as a silent spring-loaded check valve. Our axial check valve is spring-loaded and is a type of valve used to prevent reverse flow of fluids in various industrial applications, as well as to eliminate water hammer and its associated problems. This valve operates based on pressure differential; that is, it opens when the inlet pressure is high and closes when the inlet pressure is lower than the outlet pressure. Water hammer causes mechanical stresses in the piping system that can compromise the structural integrity of pipes and plumbing systems. That is why our valve is designed to close slowly, thereby eliminating water hammer, vibrations, and preventing reverse flow of the fluid. The spring in this valve ensures that the disc slowly returns to its seated position once the fluid pressure begins to decrease. This valve is designed to ensure that the fluid flows in only one direction and cannot flow backward. This valve can also function as a suction valve (foot valve) when installed at the bottom of a piping line or on a pump, provided a steel strainer is attached to one of its flanges.
