Plunger Valve

ValvesOnly is the leading Plunger Valve Manufacturer in USA. A plunger valve is one valve that controls the flow of fluids through a cylindrical moving plunger or piston inside a cylinder. It either passes or blocks fluid from passing through.

Function
Plunger valves can be adjusted to allow for varying flow rates, offering flexibility in operation.
Provides isolation in a system for maintenance or repair without draining the entire system.
Acts as a safety device to stop fluid flow in emergency situations, preventing leaks or spills.
Helps maintain or manage pressure levels within a system by controlling fluid flow.

Advantages
Plunger valves can operate without cavitation due to their optimal design.
The valve seal is in the no-flow zone, which helps extend the valve’s service life.
The sealing O-ring is located outside of the flow path, which reduces wear and tear.
Control systems can be used to precisely and efficiently control the plunger valve, which ensures optimal performance and process stability.
The open plunger design of the valve allows it to operate at an almost balanced pressure.
