Control Valves
Derwent Industries is a major supplier of automatic hydraulic control valves designed to suit a large range of pressure and flow control applications. As national distributor for well known and respected international manufacturing company DOROT, Derwent Industries can build to order; Solenoid controlled valves, pressure reducing valves, pressure sustaining and relief controlled valve, flow rate controlled valves, excessive flow shut off valves, level float controlled valves, level differential float controlled valves, attitude controlled valves, surge anticipating valves and pressure differential sustaining valves.
Available in fusion bonded epoxy coated ductile iron material, sizes range from DN 50 (50 mm) to DN 800 (800 mm) and pressure rating available in either PN 16 & PN 25. Derwent Industries also carries a range of direct acting control valves with adjustable setting allowing each valve to be set to suit the downstream pressure requirements. Direct acting control valve models are suitable for downstream pressure reduction, pressure relief or safety relief, available materials – brass, bronze and stainless steel. Direct acting control valves are available in sizes ranging from DN 15 (15 mm) to DN 100 (100 mm) depending on model, valve pressure rating ranges from PN 10 (10 bar) to PN 30 (30 bar).
Our trained staff can assemble, set and test control valves to suit your piping or pumping system pressure requirements and provide an Derwent Industries AVFI test certificate upon request.
