Two-way check valve with wafer type connection. This valve has a simple, reliable and compact design that prevents reverse flow in pipes and hydraulic equipment The discs are opened by the pressure of the circulating fluid, and let the fluid pass in the required direction. When the flow is stopped, the valve shuts off rapidly thanks to a closing spring, thus preventing reverse flow. The elastic closing guarantees perfect tightness and makes it suitable for a large variety of working fluids.
