Plunger Valve Manufacturers in India

Speciality Valve is a trusted Plunger Valve Manufacturers in India, supplying precision-engineered valves designed for accurate flow control, pressure regulation, and energy dissipation. Our plunger valves are manufactured in compliance with international standards and are widely exported to the USA, Europe, GCC, and Africa.

Function & Working

Plunger valves operate by moving a cylindrical piston axially within the valve body. This annular flow design ensures smooth throttling, reduced turbulence, and minimal vibration even under high differential pressures. The controlled flow passage prevents cavitation, making these valves ideal for applications where precise regulation and durability are critical.
