Pressure Reduce Valve

A pressure reducing valve (PRV) is a type of control valve designed to regulate and reduce the pressure of fluid or gas flowing through a pipeline or system. It works by automatically adjusting the valve's opening to maintain a set pressure downstream, regardless of changes in the upstream pressure or flow rate. PRVs are commonly used in various applications, including water distribution systems, oil and gas pipelines, and industrial processes, to prevent damage or failure of downstream equipment and ensure safe and efficient operation of the system. As a professional water pressure reducing valve supplier, we provide various types of pressure reducing valve applied in different scenario.

Pressure reduce valve detail: the basic components of a PRV include a valve body, a spring, an adjustable screw or knob, and a diaphragm or piston.

How Does A Pressure Reducing Valve Work

A pressure reducing valve (PRV) works by regulating and reducing the pressure of fluid or gas flowing through a pipeline or system. It typically consists of a spring-loaded diaphragm and a valve disc that moves up and down in response to changes in the upstream pressure.

When the upstream pressure exceeds the set point of the PRV, the diaphragm is pushed upward, which closes the valve disc and restricts the flow of fluid or gas. This, in turn, reduces the downstream pressure to the desired level. When the upstream pressure drops below the set point, the spring pushes the diaphragm downward, allowing the valve disc to open and increase the flow rate to maintain the set pressure.

Adjusting water pressure reducing valve may also include additional features such as pilot valves, sensing elements, and bypass valves to enhance their performance and control accuracy. These components work together to ensure that the downstream pressure remains constant and within the desired range, regardless of changes in the upstream pressure or flow rate.

Water Pressure Reduce Valve Applications

Pressure reducing valves are an essential component in various applications, including water, steam, air, and hydraulic systems. In the context of water systems, hot water pressure reducing valves and cold water pressure reducing valves are commonly used to regulate the water pressure in residential, commercial, and industrial buildings. Mains pressure reducing valves are also used in water distribution systems to ensure that the water pressure is within a safe and acceptable range for household or industrial use.


In addition to water systems, pressure reducing valves are used in steam and air systems to regulate the pressure and ensure safe and efficient operation of the equipment. Steam pressure reducing valves are commonly used in industrial processes to maintain a constant steam pressure in the system and prevent damage or failure of downstream equipment. Air pressure reducing valves are also used in various applications, such as pneumatic systems and HVAC systems, to regulate the air pressure and ensure optimal performance of the equipment.


Pressure reducing valves are also used in natural gas systems to regulate the pressure and ensure safe and efficient delivery of natural gas to homes and businesses. Home pressure reducing valves are installed at the point of entry of the water supply line to regulate the water pressure and protect the plumbing system from damage caused by excessive pressure.


Finally, pressure reducing valves are commonly used in hydraulic systems to regulate the pressure and ensure safe and efficient operation of the equipment. These types of pressure reducing valve are designed to withstand high pressure and flow rates, and are critical components in hydraulic systems for various industries such as construction, mining, and manufacturing.


Overall, pressure reducing valves have a wide range of applications in various industries and systems, and their proper selection, installation, and maintenance are essential for safe and efficient operation of the equipment and the system as a whole.


Pressure Reducing Valve Installation Guide

Installing a pressure reducing valve (PRV) is an important task that requires proper planning, preparation, and execution to ensure safe and efficient operation of the system. Here are the general steps involved in installing a pressure reducing valve:

  1. Determine the correct size and type of pressure reducing valve needed for the specific application based on the system's flow rate, pressure range, and other requirements.

  2. Locate the installation point for the pressure reducing valve, which should be downstream of any pressure-sensitive equipment and before any branch lines or fittings.

  3. Install a strainer or filter upstream of the PRV to prevent debris or contaminants from entering the valve.

  4. Cut the pipeline at the installation point, and install the PRV between the two sections of pipe. Use the appropriate fittings and connectors to ensure a secure and leak-free connection.

  5. Install a pressure gauge downstream of the high pressure reducing valve to monitor the outlet pressure.

  6. Adjust the set point of the PRV to the desired pressure level using the adjusting screw or knob, and check the pressure gauge to ensure that the downstream pressure is within the specified range.

  7. Start up the system and monitor the operation of the PRV and downstream equipment to ensure that everything is working properly.

It is important to follow the water pressure reducing valve manufacturer's instructions and applicable codes and standards when installing a PRV to ensure a safe and reliable installation. If in doubt, consult with a qualified professional or contact the manufacturer for assistance.
