Speciality Valve, one of the prominent Plunger Valve Manufacturers in India, presents to you technologically advanced valves designed to provide high-performance throttling and regulation. Flow control for big pipelines demands accuracy and ruggedness, particularly in water and hydropower applications. 


What is Plunger Valve? 


A plunger valve is a flow and pressure control valve that controls flow and pressure in a pipeline by operating a cylindrical plunger axially within a body. It gives very good control even on high-pressure systems and is best suited for modulating service. 


Why Required? 


Accurate control of flow is needed in water treatment plants, dams, and water supply systems. Plunger valves provide accurate modulation compared to traditional valves, which can experience cavitation or wear when throttling. These valves provide efficient operation and long service life. 


Major Components of Plunger Valve: 



  1. Valve body 

  2. Cylindrical piston or plunger Sealing rings 

  3. Actuator (manual, hydraulic, or electric) 

  4. Flow deflector

  5. Bonnet and guide mechanism  


Working of Plunger Valve: 


When it is actuated, the plunger shifts forward or backward inside the valve body, changing the flow area and therefore controlling pressure and flow rate. A flow deflector is implemented for preventing cavitation and for uniform discharge, which is crucial in high-pressure applications.  


Advantages of Plunger Valve: 



  • Improved throttling capacity Low noise and resistance to cavitation 

  • Longer service life even under stressing services 

  • Accurate control of pressure and flow 

  • Compatible for continuous operation  


Functions of Plunger Valve: 


Modulates water supply and hydropower system flow Regulates pressure reduction in pipes Reduces wear and turbulence in pipes
