Safety valve (cryogen) 2480-tGFO-PTFE r/r 1.4404/CC499K (-200°C-+200°C) PN70
Safety valves made of red brass, angular shape with threaded connection
Along with the already proven safety valve of the 2400 model range made of stainless steel, our customers will receive a similar valve made of bronze. It is distinguished by an outlet hole increased by one or two nominal diameters, thus forming two performance options within the same nominal diameter. Stable operation and the highest performance are identical to those of the 2400 model range. All bronze valves, of course, are applicable for oxygen and comply with the requirements of international standards DIN EN, ASTM, EIGA, CGA and gas manufacturer specifications.
