DOROT S300 NS

Diaphragm-actuated, Rigid Seal, Two-stage, Cushioned-closure, Globe-type Check Valve

DOROT S300 NS, is a Diaphragm-actuated, Rigid Seal, Two-stage Cushioned-closure, Globe-type Check Valve, activated by the pressure of the pipeline. The valve eliminates check valve pressure slam, frequently found in high-rise roof-tank filling pumps. The valve opens when the pump is activated, and closes slowly at a controlled pace when the pump stops.
