TESCOM™ 44-2900 Series Back Pressure Regulators
TESCOM™ 44 – 2900 Series Back Pressure Regulators The 44 – 2900 Series is designed as a compact, extremely sensitive back pressure regulator, suitable for industrial gases with a flow rate of up to 20 SCFM / 566 SLPM. The sensitivity and repeatability of the rotating stainless steel diaphragm are extremely high; the metal – to – metal diaphragm seal reduces potential leakage to the greatest extent. It is very suitable for research and development laboratories, process systems and pilot plants. Specifications – Control Pressure Range: 0 – 12, 0 – 25, 0 – 50, 0 – 100, 0 – 150 psig; 0 – 0.83, 0 – 1.7, 0 – 3.4, 0 – 6.9, 0 – 10.3 bar – Materials: – Body: 316 stainless steel – Seat Positioner: PEEK – O – rings: Viton®, Kalrez® – Diaphragm, Spring: 316 stainless steel – Other Parts: 316 stainless steel – Operating Temperature: – 15°F to 140°F / – 26°C to 60°C – Port Size and Type: 1/4 NPTF – Flow Capacity: Cv = 0.30 – Load Type: Spring – Weight: 3 lb / 1.4 kg Features – 316 stainless steel diaphragm achieves a complete metal – to – metal seal and high sensitivity. – The large sensing orifice area ratio achieves a low seat pressure differential and good repeatability. – Maintains air – tight closure at all back pressures. – Flow capacity Cv = 0.30. – Panel mounting is standard. – Suitable for non – corrosive and corrosive gases. |
