Plunger Valve Manufacturer in USA – SVR Global
SVR Global is a specialized Plunger Valve Manufacturer in USA, delivering precision-engineered solutions for waterworks, power plants, dams, and industrial process systems. Our plunger valves are designed for accurate flow regulation, pressure control, and energy dissipation even under extreme operating conditions. With advanced engineering, robust construction, and customizable options, SVR Global ensures reliable performance across diverse industries.
Function & Working
Plunger valves, also known as flow control valves, regulate pressure and flow by moving a plunger axially inside the body. The annular flow passage design provides stable control with minimal cavitation and reduced turbulence. These valves are ideal for applications where fine throttling and energy dissipation are required, ensuring long service life even under fluctuating loads.
Advantages
- Precise linear flow control with wide throttling range 
- Low operating torque with smooth actuation 
- Cavitation- and vibration-resistant design 
- Long-lasting sealing performance with replaceable rings 
- Compact design suitable for retrofitting with hydraulic or electric actuators
