DOROT S80 QR (2W) is a Diaphragm-actuated, Rigid Seal, 2-way quick pressure relief globe valve, activated by the pressure of the pipeline. The valve opens instantly once pressure in the pipeline exceeds a safe preset level; relieving excessive pressure in the system. When the pressure returns to normal, the valve closes slowly, at an adjustable pace.
