Hydraulic Operated Plunger Valve

The Hydraulic Operated Plunger Valve ARL-HOPV is a straightway regulating and control valve which has an annular flow cross-section in any position. Inside the body of the Hydraulic Operated Plunger Valve ARL-HOPV, the open plunger (also referred to as piston) is moved axially in flow direction by a crank gear towards the sealing seat of the valve. These units function as regulating and control devices which, by continuous narrowing towards the seat, generate different pressure losses in pipeline systems to change the flow rate in dependence of the regulating distance. Built to handle robust performance demands, this valve features a sizing scope of DN200-1600 and a pressure class rating of PN6-25.
