Plunger Valve Manufacturer in USA
A plunger valve is a critical control and energy-dissipation component used in high-pressure and high-head water systems to regulate flow while safely reducing pressure. These valves provide smooth throttling, excellent cavitation control, and vibration-free operation in demanding hydraulic and infrastructure applications.
SVR Global is a leading Plunger Valve Manufacturer and Supplier in USA, delivering engineered plunger valve solutions for water transmission, hydropower, irrigation, and municipal infrastructure projects. Our plunger valves are designed for precise flow control, controlled energy dissipation, and long service life in both standard and severe-service installations.
With extensive experience supporting EPC contractors, utilities, and infrastructure operators, SVR Global supplies plunger valves that meet stringent project specifications and international water industry standards.
What Is a Plunger Valve?
A plunger valve is a control valve used to regulate flow and reduce pressure in high-pressure pipelines. It operates using a cylindrical plunger that moves axially within the valve body, allowing controlled throttling while minimizing cavitation, noise, and vibration. Plunger valves are widely used in water transmission pipelines, dam outlet works, and hydropower systems where large pressure drops must be safely managed.
