TESCOM 44-4700 Series: Precision Gas Control For Low-Pressure And Vacuum Environments

Product introduction:

The TESCOM 44-4700 series pressure regulator is engineered to handle special, flammable, and industrial gases in low-pressure and vacuum systems with unmatched safety and precision. Its diffusion-proof metal diaphragm seal ensures gas purity and zero leakage, making it ideal for analytical instruments, sampling processes, and pilot plant operations where contamination risks are critical.

Key Features:

Metal Diaphragm Sealing: Eliminates diffusion and ensures hermetic containment of hazardous or valuable gases.
Low-Pressure/Vacuum Performance: Maintains stable regulation in challenging environments down to 0.1 psig (0.007 bar) for vacuum applications.
Corrosion Resistance: 316 stainless steel construction with Hastelloy®/Vespel® seals for compatibility with aggressive gases.
Compact Design: Lightweight (2.5 lb/1.1 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).
Leakage Standards: UL-rated low leakage (<10⁻⁷ mbar·L/s helium) for toxic or flammable gases.
Temperature Range: -40°C to 71°C (-40°F to 160°F) with optional PFA seats for extreme media.

Applications:

Analytical Systems: Gas chromatography, mass spectrometry, and environmental monitoring.
Chemical Processing: Handling hydrogen, ammonia, and other pyrophoric gases.
Energy Research: Fuel cell testing, CO₂ capture, and cryogenic systems.
Semiconductor Manufacturing: Ultra-pure gas supply for wafer fabrication.

Why Choose 44-4700?

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