Plunger valves are used mainly for water flow control and regulation in the pipeline, as well as discharge valves in dams. The axial movement of the piston allows flow regulation. Plunger needle valves perform very well, with silent movement, avoiding noises, water hammer effect and cavitation. Low pressure drops for opening more than 50%, while higher pressure loss happens whenever opening is lower than 40%.

Executions: gear box, electric actuator, hydraulic cylinder,hydraulic cylinder with counterweight lever.
