Check valves

Non-return devices in pumping stations, water supply and sewage networks are of great importance in protecting
equipment and networks. In consequence, the criteria for selecting these devices must be based on quality, reliability and durability. Belgicast offers the widest range of check valves to guarantee the safety of your installations.
Use  the most suitable valves for your particular requirements, taking water type (clean or waste), working pressure and water hammer performance into account.

Y-STRAINER DN 50/300, PN 16.
Characteristics: · Simple strainer for network protection services.
· Easy maintenance and installation.
· Widely used in irrigation to protect hydrants.

DUAL PLATE CHECK VALVE DN 40/1200, PN 10...250.
Operation: · The dual plates open under the pressure exerted by the pumped flow and close immediately after the pump stops, due to the pressure applied by the water column and closing spring.
· When installing the check valve at pump outlet, take care to make the installation as far as possible from diffusing cone and elbows. Choose an area of stable flow. It is recommended to install the valve after a straigh length of pipe 5 times higher its DN.

AXIAL DISC CHECK VALVE DN 50/250 PN 10/16
Operation: When the pumping equipment is in operation, the disc is pushed back allowing the fluid to flow. When the pump stops, the disc is quickly closed by spring pressure before any overpressure occurs due to the return flow.
