Tekno Valves introduces the SSWN-32/52 series of stainless steel diaphragm gland seal valves, designed for lecture bottles in laboratory, research, and analytical applications.
The valves feature SS 303 bodies and internal components, with seat material options including PCTFE, PEEK, or PVDF to accommodate a wide range of gases and operating conditions. An Inconel lower diaphragm ensures superior sealing performance, while four upper stainless steel diaphragms provide enhanced durability and long service life.
Rated for a maximum working pressure of 207 bar (3,000 psig), the valves are available with CGA 170 or CGA 180 outlets and inlet options of 3/8-18 NGT or 0.750-16 UNF.
The SSWN-32/52 series is certified to EN ISO 10297:2017 by BAM and complies with CGA V-9:2019 standards. Each valve undergoes production testing with helium to an internal and external leakage rate of 10⁻⁷ mbar·l/sec at valve tightness pressure, ensuring exceptional leak integrity for demanding laboratory and analytical environments.
