GESTRA RK41 Check Valve / Non-Return Valve / Backflow Preventer

GESTRA RK41 Check Valve/Non-Return Valve The RK41 series wafer-type lift check valve opens when the opening force exceeds the closing force. The opening force depends on pressure or flow rate, while the closing force is determined by the closing spring tension, closing weight, installation position, and the size of the check valve. The wafer design significantly reduces weight compared to traditional valves.
They have been widely used in the shipbuilding and marine industries, petrochemical industry, pharmaceutical industry, heating and cooling systems, ventilation, fire protection systems, water industry, and the beer and beverage industries.
