Cast Steel Pilot Operated Piston Type Pressure Reducing Valve For Steam Use

This series of pressure reducing valves belongs to the pilot piston type pressure reducing valve. It consists of two parts: the main valve and the pilot valve. The main valve is composed of parts such as valve seat, main valve disc, piston, spring, etc. The pilot valve is mainly composed of parts such as valve seat, valve disc, diaphragm, spring, and regulating spring. By adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the change in outlet pressure, and driving the piston to adjust the size of the flow area at the throttle position of the main valve through the opening and closing of the pilot valve, the pressure reducing and stabilizing function is achieved. The presure reducing valve product is mainly used for steam pipelines, playing a role in reducing pressure and stabilizing pressure.

Product applications:

• PRVs are utilized in water supply systems to lower the high incoming water pressure to a safe and dependable level for residential and commercial use.
• To control the pressure of fluids and gases including steam, compressed air, and natural gas, PRVs are utilised in a variety of industrial operations.
• In order to maintain the necessary water pressure and flow rate for sprinklers and fire hydrants, PRVs are utilised in fire protection systems.
• To control fluid and gas pressure and uphold secure working conditions, PRVs are employed in oil and gas production systems.
• In chemical processing plants, PRVs are used to control the pressure of corrosive and dangerous fluids and gases.

Product advantages:

• Pipes, fittings, valves, and other equipment may get harmed by excessive pressure in fluid systems. By lowering and managing the pressure to a safe and constant level, PRVs aid in the protection of machinery and plumbing systems.
• Increased energy use and waste can also be caused by high pressure in fluid systems. By lowering the pressure and flow rate to the bare minimum necessary for the particular application, it increases energy efficiency.
• Contributes to the maintenance of safe working conditions by avoiding overpressure, lowering the possibility of mishaps, and preventing equipment failures & Contributes to the reduction of water waste by avoiding leaks and wasteful water use brought on by high pressure.
• PRVs aid in maintaining the proper pressure and flow rate in industrial operations, which is essential for assuring constant product quality.
• Easy and swift operation
