Request a quoteA packed type cylinder valve for high purity corrosive gases, rated 200 bar with a 3.3 mm orifice and Cv 0.3, where the gas never reaches the operating mechanism, so the valve is free from seizure with corrosive gases. The spindle is mechanically linked to the handwheel for positive operation at low closing torque, all internal parts are replaceable, and the gland packing is adjustable, so a leak past the spindle is corrected by retightening the gland nut. A low internal volume suits hygroscopic, corrosive and high purity gases where inert purging is needed before opening. Bodies in AISI 303 or 316L stainless steel, brass CW617N or ASB, marked to TPED.
