 Pressure Control Valve
Pressure Regulating Valve(Precision Regulator for Analytical Equipment)

This is a compact,lightweight precision pressure regulator with superior repeatability to provide reliable and speedy regulations. Since all the components are perfectly cleaned before assembly,this model is ideal for high-sensitivity instruments for analysis required for R&D activities.



  • High-precision control characteristic
    High control performance with repeatability within a range of±1% against fluctuations in pressure on the primary side and load resistance variations on the secondary side
  • Perfect for panel mounting
    Flow inlet and outlet are located on the back of the product to facilitate easy pipe connection. Additionally,it is compact in size and light in weight,ideal for panel instrumentation systems.
  • Bleed-free
    All units are subjected to a rigorous leak test before shipping though the product is bleed-free.
  • Gas chromatographs
  • Scientific instruments
  • Gax mixing systems in various fields
