DOROT S75 PS/M 3W, is a Weir-type diaphragm, 3-way, automatic pilot-controlled back-pressure sustaining/relief globe valve, with manual override. The valve maintains a steady, preset pressure in the network, upstream of its location. Should upstream pressure exceed preset values, the valve opens to minimize losses. Should upstream pressure fall below preset values, the valve closes drip-tight.
