Middleeast Valve is well-known for supplying high-quality Pressure Reducing Valve in UAE, with delivery across Dubai, Abu Dhabi, Sharjah, and Ajman. Our valves are engineered to provide reliable pressure regulation in diverse industrial and utility systems.

What is a Pressure Reducing Valve?

A pressure reducing valve (PRV) is a specialized mechanical device designed to lower and stabilize the incoming pressure of fluids or gases to a safe, controlled level downstream. This prevents equipment damage, ensures smooth system operation, and delivers consistent flow even when inlet pressure fluctuates.

Function and Working Principle of a Pressure Reducing Valve

Function:
The main purpose of a PRV is to reduce high inlet pressure and maintain it at a constant, lower outlet pressure. This helps protect pipelines and equipment, ensures operational safety, and enhances energy efficiency.

Working Principle:
A PRV balances the force of the incoming fluid against a spring mechanism:

  • High Pressure Inlet: The fluid enters the valve at elevated pressure.
  • Spring Adjustment: A spring-loaded diaphragm or piston reacts against the pressure to achieve the desired downstream level.
  • Pressure Control:The valve automatically adjusts its opening to maintain the pre-set outlet pressure, regardless of upstream fluctuations.

This mechanism guarantees steady downstream pressure, which is crucial for industries such as water supply, oil & gas, and process plants across the UAE.

How Does a Pressure Reducing Valve Work?

  • Sensing Pressure: The diaphragm continuously senses the outlet pressure.
  • Regulating Flow: If the outlet pressure increases beyond the setpoint, the valve closes slightly; if it drops, the valve opens further to allow more flow.
  • Pressure Adjustment: Operators can fine-tune the downstream pressure using a manual adjustment screw.

This constant feedback system ensures reliable performance, even under variable load conditions.

 

Components of a Pressure Reducing Valve

  1. Body – Constructed from durable materials like brass, stainless steel, or cast iron, built to handle high pressure and temperature changes.
  2. Diaphragm or Piston – A responsive element that senses downstream pressure and enables smooth modulation.
  3. Spring Mechanism – Governs valve operation and allows outlet pressure adjustment.
  4. Seat and Disc – Provide tight sealing to prevent leakage and maintain accuracy.
  5. Adjustment Screw – Enables manual control to set the desired outlet pressure.
  6. Inlet & Outlet Ports – Direct the flow of fluid through the valve.
  7. Strainer (Optional) – Protects the valve internals from debris and extends service life.
