HIGH PURITY REGULATING VALVES

A line of high purity regulating valves for electronic grade and other high purity gases is also
available. This includes pressure reducing valves, back pressure valves and valves suitable for
differential service.
Valve bodies are investment cast 316L stainless steel, with internal trim 316L bar stock.
Interior (wetted) surface finish is 15 micro inch or better. The finish is electropolished. Also, all
maintenance may be carried out without removing the valve from the line.
Sizes are ½” to 1½”, butt weld ends, 0.065 wall (½” size, 0.049 wall). Spring ranges are typically up
to 400 psig (28.12 kg/cm2) control.
Temperature limits are 400°F [478K] to -425°F [19K]. All valves are cleaned for high purity gas
compatibility.
