TESCOM^™ 44-2900 Series backpressure regulator is designed to be compact, extremely sensitive and for industrial gases with flows up to 20 SCFM. Convoluted stainless steel diaphragm provides excellent sensitivity and repeatability; metal to metal diaphragm seal minimizes the potential for leakage. Ideal for use in R&D laboratories, process systems and pilot plants.

Features & Benefits

• 316 Stainless Steel diaphragm provides metal to metal sealing integrity and good sensitivity
• Large sensing seat area ratio provides a low crack to reseat pressure differential and excellent repeatability
• Bubble-tight shutoff at all reseating pressure
• Flow capacity Cv = .3
• Panel mounting standard
