Product Introduction:
The TESCOM 44-4600 series single-stage pressure regulator is engineered to deliver uncompromising precision and safety in handling special, flammable, and industrial gases within low-pressure and vacuum environments. Its integrated anti-diffusion metal diaphragm sealing system ensures gas purity and eliminates leakage risks, making it ideal for analytical systems, sampling operations, process control, test facilities, and calibration tasks.
Key Features:
- Metal Diaphragm Sealing: Hermetically seals gas to prevent diffusion, ensuring purity in critical applications.
- Low-Pressure/Vacuum Performance: Maintains stable regulation in challenging environments, including vacuum conditions.
- Corrosion Resistance: Constructed with 316 stainless steel and Hastelloy® components for durability in aggressive media.
- Compact Design: Lightweight (2.5 lb/1.1 kg) and space-efficient 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: Hydrogen, ammonia, and other pyrophoric gas management.
- Energy Research: Fuel cell testing, CO₂ capture, and cryogenic systems.
- Semiconductor Manufacturing: Ultra-pure gas supply for wafer fabrication.
Why Choose 44-4600?
- 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.
