Pressure Reducing Valves

Pressure reducing valves, also called pressure regulating valves, are mechanical devices designed to control and maintain a lower, more stable pressure in a system. Often abbreviated as PRVs or PRDs (Pressure Reducing Devices), pressure reducing valves are crucial components in many industries–protecting water systems from damage resulting from excessive pressures of water supply. A pressure reducing valve ensures a consistent flow and features a gauge–displaying a real-time monitoring of current pressure levels. These PRVs help minimise water consumption and minimise noise, maintaining and stabilising constant liquid flow in multiple domestic, commercial, and industrial installations. In addition, pressure regulating valves come in male and female PRVs with different connection sizes, ensuring long-lasting regulation in various systems.

Why Buy Pressure Reducing Valves?

The primary purpose of a pressure reducing valve is to reduce the high-pressure fluid or gas entering a system to a lower, manageable pressure level. This ensures the downstream equipment and components are not subjected to excessive pressure–leading to damage or inefficient operation. Using a pressure reducing valve saves water and energy, prevents leaks, and helps save money by protecting pipes and seals from bursting.

Materials of Pressure Reducing Valves:

The materials for pressure reducing valves can vary that rely on the specific requirements of the application and the controlled fluid type. However, common materials for pressure-limiting valve bodies include various metals or alloys, such as brass, stainless steel, cast iron, or bronze. The internal components of pressure reducing valves, such as the seat, diaphragm, and springs, are often crafted from materials that can withstand the corrosive or abrasive properties of the fluid, such as stainless steel, rubber, or elastomers.

Popular Types of Pressure Reducing Valves:

Pressure-reducing valves come in the following types:

  • Direct-acting PRVs – These valves operate directly in response to changes in downstream pressure.
  • Pilot-operated PRVs – They use a pilot valve to control the main valve, allowing more precise and stable pressure control.
  • Hydraulic PRVs – These valves use hydraulic pressure to control the main valve's position.

Maintenance and Considerations of Pressure Reducing Valves:

Regular inspection and maintenance are among the critical considerations to ensure the proper functioning of pressure reducing valves. Ensure to consider the primary considerations, including:

  • Correct sizing and selection of the valve based on the application's requirements.
  • Monitoring and adjusting the valve as needed to maintain the desired outlet pressure.

Typical Applications of Pressure Reducing Valves:

Pressure reducing valves find multiple typical applications in various facilities, including:

  • Water Supply Systems
  • Industrial Processes
  • Gas Distribution
  • HVAC Systems
  • Steam Boilers
  • Oil and Gas Production
  • Fire Protection Systems
  • Food and Beverage Industry
  • Pharmaceuticals
  • Laboratory Equipment
  • Irrigation Systems
  • Aerospace
  • Shipbuilding and Maritime Applications.
