A pressure reducing valve (PRV) is an automatically controlled valve that decreases high inlet pressure or to reduce any excess pressure in a system to a constant lower outlet pressure irrespective of changes in upstream pressure or flow rate. It finds applications in liquid and gas systems, such as water, steam, air, and chemicals. Pressure Reducing Valve are self-acting and provide constant downstream pressure without the need for control systems or external power.

Basic Components of the PRV’s are Inlet and outlet ports, adjusting screw (sets desired pressure), Spring and diaphragm/piston assembly and Valve seat and disc (regulates flow)

Automatic Control Valves, Pressure Reducing Valves

Having the right pressure in a fluid system, it is crucial to have safety and efficiency. Industrial pipes, heating systems, or domestic water lines – all can be ruined by excess pressure and be energy-wasteful. That’s where the pressure reducing valve are preferred.

Purpose of PRV is to protect downstream equipment, pipelines, and instruments from excessive pressure receiving from upstream and to maintain a consistent and safe working pressure in a system. Also, PRV’s are used to improve efficiency by avoiding energy losses due to high pressure and to reduce water beats / hits and system stresses due to sudden pressure changes.

Working Principle

The operation of a PRV is one of forces balance: inlet pressure is opposed by a spring-loaded piston or diaphragm. When the outlet pressure decreases, the valve opens to provide greater flow. When the pressure equals the set value, the valve closes slightly to throttle the flow.

The valve contains a spring-loaded diaphragm or piston. When downstream pressure is lower than the set point, the spring allows the valve to open and allowing flow. As the downstream pressure rises to the set value, it pushes against the diaphragm /piston, compressing the spring, and slowly closing the valve.

The valve continuously modulates to maintain a constant outlet pressure. In short

  • High-pressure inlet fluid is supplied to the valve.
  • The spring is pre-set to a fixed downstream pressure.
  • With increasing downstream pressure, it displaces the diaphragm or piston.
  • Once the equilibrium is established, the valve modulates to keep the set pressure.
  • Manual intervention in providing constant pressure is prevented by automatic modulation.

Different Types of Pressure Reducing Valves.

PRVs come in many types, each appropriate for particular media and pressures.

Direct Acting Pressure Reducing Valve.

It utilizes spring and diaphragm to reduce the downstream pressure directly. It is pressure-sensing and suitable for small systems.

Applications: 

  • Domestic water supply – Domestic plumbing, Commercial buildings and Irrigation systems

Function is To lower incoming mains water pressure to a safe level for domestic or commercial use.

  • Small industrial plant equipment – Power generation plants, Sterilizers and Steam heaters

Purpose is to provide constant steam pressure for effective heat transfer and to avoid steam hammer.

  • Compressed Air Systems – Pneumatic tools, Industrial automation

Purpose is to provide steady air pressure to tools and actuators, without pressure spikes.

  • Chemical and Process Industries – Reactors, Tank pressure control and Mixing and dosing systems

Purpose is to provide precise pressure conditions for safety and product consistency.

Advantages: 

  • Avoids equipment over-pressurization
  • Saves energy
  • Enhances system performance and consistency
  • Reduces manual pressure adjustment requirement
  • Improves safety and minimizes risk of system failure
  • Simple design
  • Rapid action

    Pilot-Operated Pressure Reducing Valve

     

It uses pilot valve to sense the downstream pressure and actuates the main valve. It provides more precise control and greater flow capacity than direct-acting types.

Applications:

  • Steam piping
  • Large industrial and HVAC systems
  • Process plants

Advantages:

  • High precision
  • Can handle large pressure drops
  • Constant performance under varying flow

Limitations

  • Cannot act as a complete shut-off valve. It is not 100% Control valve
  • Performance may degrade over the period due to wear & Tear, scaling, or corrosion or some foreign materials intrusion.

Conclusion

Pressure reducing valves are an essential part of fluid systems today. From a household water system to a modern industrial steam facility, PRVs ensure safety, reliability, and efficiency through regulation of downstream pressure to a predetermined level.

By understanding the operation principle, models, and application, users can choose the best valve for his or her system requirement. Speciality Valve designs and provides precise PRVs to work efficiently in different industries, pressures, and forms of media. Our valve is precision-made, long-lasting, and non-clogging.
