ELIPTIX R-20 QR (3W)

Weir-type, Elliptical-shaped Diaphragm, 3-way, Quick Pressure Relief Control Valve

ELIPTIX R-20 QR, is a Weir-type, Elliptical-shaped Diaphragm, 3-way, Quick Pressure Relief Control Valve, activated by the line pressure. The valve opens instantly once pressure in the pipeline exceeds a safe preset level; relieving excess pressure in the system. When the pressure returns to normal, the valve closes gradually, at an adjustable pace.
