Gauge Valves | Features and Benefits

AS-Schneider Gauge Valves are designed, manufactured and tested according to DIN 16270, DIN 16271 and DIN 16272. According to these standards the valves are applicable for a max. allowable (Working) Pressure (PS) of 250 bar (brass) respectively 400 bar (carbon steel and stainless steel) and a max. allowable Temperature (TS) of 120°C for liquids, gas or vapors.

The max. allowable Temperature (TS) of 120°C is considering the requirement that valves and measuring instruments need to be protected against heating by hot media. This can be achieved by syphons or by instrument impulse lines with sufficient length. However the AS-Schneider valves can be used for temperatures up to 300°C - PTFE up to 232°C, Graphite up to 300°C.

Standard Features
