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.
