Brief Introduction
The plunger valve is a straightway regulating and control valve which has an annular flow cross-section in any position.
Inside the body, 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.
Plunger valves are 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.
