Water control element used in the pump suction line to prevent the water in the suction pipe from draining into the reservoir and thus prevent the pump from running without water. With the filter (Crepine) connected in front of the clapper, it prevents the entry of coarse particles into the pump and the line. In this way, it is ensured that the pump works with clean water and wear of the pump is prevented. Prevents backflow of water in the suction line when the pump stops. In this way, it eliminates the risk of air in the pump and running without water. The spring-loaded check valve inside the body operates in the direction of the fluid indicated on the body. It operates in a vertical position with the flow upwards. When the pump stops, the spring pushes the flapper in the closing direction and ensures complete sealing. The pipework inside the reservoir is installed perpendicular to the suction ends. Suitable for use in clean water lines. It prevents the pump from running idle by keeping the suction line full. Saves energy. Sealing is provided with EPDM gasket. The spring valve system is designed to operate silently and with minimum pressure loss. The filter (Crepine) is made of AISI 420 stainless material with flange. The body is GGG 40 casting. Sealing gasket is EPDM. Connection bolts A2 70, nuts A4 80 stainless steel. The coating is thermoplastic powder epoxy and WRASS approved.
