DOROT S300 CV, is a Diaphragm-actuated, Rigid Seal, Hydraulic Non-return Globe Valve, activated by the pressure of the pipeline. The valve opens when upstream pressure is higher than the downstream pressure, and closes, drip-tight in cases where upstream pressure is equal to, or lower than the downstream pressure. Opening and closing speeds are slow and controllable, preventing risk of water hammer or surge.
