Description
A Pressure Reducing Valve is a control valve designed to automatically reduce higher inlet pressure to a predetermined, lower and stable outlet pressure, regardless of fluctuations in upstream pressure. It ensures safe, efficient, and reliable operation of water and fluid systems by preventing excessive pressure from reaching downstream equipment.
Pressure Reducing Valves operate without external power and use internal diaphragm or piston mechanisms to regulate pressure accurately. They are widely used in fire protection systems, water supply networks, HVAC systems, and industrial piping applications. Manufactured from high-quality materials such as Ductile Iron, Brass, and Stainless Steel, PRVs offer excellent durability, corrosion resistance, and long service life while reducing maintenance and operational risks.
