Pressure Reducing Valve

A pressure reducing valve is an automatic regulating valve that stabilizes the high-pressure medium on the inlet side within a set low-pressure range through the throttling effect of internal sensitive components. At the same time, with the help of the medium's own pressure feedback, it automatically compensates for pressure fluctuations and ensures constant outlet pressure.Widely used in industries such as petrochemicals, metallurgy, power, food and pharmaceuticals, and building HVAC, it is installed at the outlet end of high-pressure pipelines, storage tanks, and pressure vessels to provide a stable pressure medium for downstream equipment, prevent overpressure damage to equipment, and ensure safe and efficient system operation.

Common Types

  • Piston type pressure reducing valve: relying on piston sensing pressure changes, strong impact resistance, suitable for high-pressure working conditions
  • Thin film pressure reducing valve: using elastic thin film transmission, with high adjustment accuracy, suitable for low-pressure voltage stabilization scenarios
  • Bellows pressure reducing valve: excellent sealing performance, suitable for pipelines transporting corrosive or high-purity media
  • Pilot operated pressure reducing valve: precise control of the main valve through the pilot valve, wide voltage stabilization range, suitable for high flow systems

Structural Advantages & Corresponding Benefits

  1. Double membrane precise voltage stabilizing structure

  • Special point: Adopting a dual diaphragm linkage design, the diaphragm is made of corrosion-resistant fluororubber material, with high pressure sensing sensitivity.
  • Result:The fluctuation error of export pressure is ≤± 2%, and the stabilizing effect far exceeds that of a single diaphragm structure, making it suitable for pressure regulation in complex working conditions.

  1. Quick disassembly filter anti blocking structure

  • Special point: The imported end is equipped with a stainless steel detachable filter element, paired with a clamp quick installation design, and the filter aperture can be customized.
  • Result: Intercept impurities in the medium, avoid valve core blockage, quickly disassemble and maintain without tools, and extend the service life of the valve.
