Product introduction:
The TESCOM PS-3400 series two-stage regulator is engineered for precision and safety in handling toxic, flammable, and pyrophoric gases with low-flow requirements. Its compact, high-purity design and auxiliary-seal diaphragm ensure reliable performance in critical environments such as semiconductor manufacturing, chemical processing, and research laboratories.
Key Features:
- 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.
Technical Advantages:
- 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.
Applications:
- 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.
Why Choose PS-3400?
- 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.
