Product introduction:

• Dual-Stage Precision: Reduces pressure in two stages for stable, consistent output, minimizing fluctuations in gas delivery.
• Ultra-High Purity: Metal valve film sealing technology prevents diffusion and contamination, maintaining gas integrity.
• Hazardous Gas Compliance: Auxiliary seal diaphragm and static-dissipative components mitigate risks in toxic or flammable gas applications.
• Compact Design: Lightweight (3.5 lb/1.6 kg) and space-saving for benchtop or inline installations.

• Pressure Handling: Inlet up to 3,000 psig (207 bar), outlet adjustable to 0–150 psig (0–10.3 bar).
• Materials: 316 stainless steel body with Hastelloy®/Vespel® seals for corrosion resistance.
• Leakage Resistance: UL-rated low leakage (<10⁻⁷ mbar·L/s helium) for safe containment.
• Temperature Range: -40°C to 71°C (-40°F to 160°F) with optional Teflon PFA seats.

• Semiconductor Fabrication: Ultra-pure gas supply for CVD and etching processes.
• Chemical Labs: Handling ammonia, chlorine, and other toxic gases.
• Medical & Biotechnology: Oxygen/CO₂ regulation in sterilization and cell culture systems.
• Energy Research: Hydrogen fuel cell testing and CO₂ capture.

• Safety: Compliant with USP Class VI, BPE, and SEMI F57 standards for biopharm and semiconductor industries.
• Reliability: No elastomer-to-gas contact in metal-sealed models for zero contamination.
• Ease of Use: Quick-connect fittings and tool-free maintenance reduce downtime.

Product highlights:
Inlet attenuation characteristics: Even in the face of inlet pressure fluctuations of 0.06, 100 psig (0.004, 6.9 bar), it can still maintain a stable output, showing the control ability.
Innovative seal design: Auxiliary seal and recovery bonnet port design, effectively prevent leakage.
High precision and sensitivity: Dual rotary valve membrane structure, significantly control accuracy and response speed, to meet the needs of fine pressure regulation.
Metal-to-metal valve film seal: strengthen the sealing performance of the valve body, reduce the risk of leakage, and ensure long-term stable operation.
Integrated valve film and valve connection: Enhanced seat sealing integrity to further protect product durability and reliability.
