Stainless Steel Flange Pressure Reducing Valve
The Stainless Steel Flange Pressure Reducing Valve is a pilot operated piston control device used to reduce and stabilise pressure in a system to ensure the safe operation of equipment and systems. It is designed for water, compressed air, neutral gases and non viscous liquids up to 95°C. The valve is mainly used on steam lines and is particularly suitable for environments with high and frequently changing flow rates and significant fluctuations in inlet pressure.
This pressure reducing valve has a pressure-balanced piston design with low start-up torque, enabling stable operation under fluctuating inlet pressures and flow rates, and regulating a higher inlet pressure to a constant lower outlet pressure. Its rotationally symmetrical guide design and annular cross-section ensure excellent operating performance. The valve body is made of micromachined bronze overlay, which is wear-resistant, corrosion-resistant and impermeable. Controlled operation is achieved by differential pressure of the medium itself, providing the required operating torque. Equipped with a double bearing weight lever to prevent the transfer of drop hammer forces to the valve bearings. The modular design of the drop hammer can be customised and adjusted to suit the operating conditions, making it suitable for a wide range of scenarios such as gas piping, steam piping and water supply piping.
Model: Pressure Reducing Valve
Pressure Range: 1.6～6.4MPa
Material: Stainless Steel 304/316
Features
- Pressure Regulation: Stainless steel pressure-reducing flange ball valves reduce the high inlet pressure to a stable outlet pressure by regulating the flow pressure of the medium to ensure the stable operation of the system within the safety range.
- Wide Range of Media: Suitable for water, compressed air, neutral gases and non-viscous liquids up to 95°C. Particularly suitable for handling steam lines with large variations in flow and pressure.
- Standard Flange Connections: The flange end design in accordance with EN 1092-2 facilitates installation and removal.
- Optimised design and control： The straight-through valve design is fitted with customised controls. The pressure-balanced valve piston design provides low start-up torque and ensures stable pressure regulation.
- High Sealing and Durability： Resilient seals provide high durability in flow-free areas; body piston guides are made of abrasion- and corrosion-resistant micromachined bronze over-welded to resist penetration.
- Self-Medium Regulating Capability: Self-media controlled pressure regulation, with a minimum of 2 bar differential pressure to generate the torque required for operation, maintains a stable outlet pressure, independent of inlet pressure and flow fluctuations.
