Product description

Highlights at a glance

  • Medium flow rate, high flow rate, and ultra-high flow rate are all available for selection. The connection form can adopt various interface methods: threaded connection, welded pipe, clamp, etc. The output pressure is stable and the flow rate variation rate is small.
  • SUS316L High Purity Single Stage Regulator, Precise Pressure Control for Semiconductor & Lab
  • Wide High Inlet Range, 0-25psi Low Stable Outlet Pressure, No Flow Fluctuation
  • Mirror Polished Dead-Space-Free Flow Path, Low Adsorption for Clean CIP Piping
  • Full 316L Body Corrosion Resistant, Ideal for High-Purity & Corrosive Special Gas
  • Standard Double Ferrule Ports, Zero Leakage Sealing, Easy Installation & Maintenance
  • Body, diaphragm and valve core all made of SUS316L stainless steel with sufficient molybdenum, resist corrosive special gas like HCl, silane, trichlorosilane, anti salt spray & acid alkali, no corrosion leakage for long-term corrosive medium delivery.
  • One-piece forged body without welds or pores, stable structure under 500psi high inlet pressure, high pressure resistance to avoid valve burst risk.
  • High precision balanced diaphragm & spool assembly with sensitive pressure response; outlet pressure stays constant 0-25psi even with inlet fluctuation, pulse-free flow to stabilize chip & chromatography process.
  • Mirror polished inner flow path with low roughness, no dead space or medium residue, free of impurity precipitation, fully compatible with CIP & SIP sterilization.
  • Full degreasing & dust-free nitrogen purge before delivery, no oil or metal dust inside, avoid contamination of UPW & electronic specialty gas, compliant with semiconductor GMP standards.Standard double ferrule inlet & outlet fit seamless stainless tubing, no welding or PTFE tape required for fast wrench assembly. Dual ferrule clamping prevents leakage under vibration & temperature cycling.Standard port sizes including 1/4, 3/8, 1/2 inch, fully interchangeable with all -Lok compression fittings, filters and valves.
    • Frequently asked questions

    Our standard lead time is 2 weeks, significantly faster than the industry average of12-20 weeks. We achieve this through modular design and a strategic inventory ofcore components (SS316L bodies, diaphragms). For urgent project needs, pleasecontact our engineering team for "Fast-Track" options.

    Every single product undergoes a rigorous Helium Leak Test using ahigh-sensitivity mass spectrometer. We guarantee a leak rate of less than 1x10-3mbar-l/s. A detailed test report with a unique serial number is provided with eachdelivery.

    Yes. We hold the CE-PED (Pressure Equipment Directive) certification (NB0036/0035 equivalent). This is not just a general CE mark, but a specific safetycertification for high-pressure equipment, which is a mandatory requirement for 90%of industrial projects in Europe (,, etc.).

    We strictly use SS316L (VIM/VAR grade) for ultra-high purity and hydrogenapplications to prevent hydrogen embrittlement. All raw materials come with EN10204 3.1 Mill Test Reports. For corrosive gases, we offer Hastelloy and Elgiloydiaphragm options.

    Absolutely. We specialize in "Lego-style" modular customization. Whether it's a70MPa hydrogen manifold or a semi-automatic changeover system for a lab, ourengineers can provide a professional 3D design and technical datasheet within 24-48nours.

    Yes, we welcome sample orders. We understand that in the semiconductor andenergy sectors, "seeing is believing." You can test our Ra < 0.25um surface finish andoressure stability before committing to a bulk purchase.
