OCV 108-2QR, is a diaphragm-actuated, rigid sealing, 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.
