Spectropur Purge- and connection block SBE/3-MV3
Product Features
- Minimized purge volume of only 1,4 cm³
- The capillary tube allows purging into the cylinder valve
- Metal-to-metal seal to atmosphere using metal diaphragms made of Hastelloy C276
- All gas-wetted parts made of stainless steel SS 316L, Hastelloy C276, and PCTFE or PVDF respectively
- Fully functional even when valves are evacuated
- Minimum particle generation, as no parts are exposed to friction and no spring is in the gas wetted area
- Embedded soft seat seal made of PCTFE or PVDF permits frequent operation without loss of tightness
- Modular design for easy replacement of internal parts
- Clearly legible position indication (on/off)
- High surface quality
- 100 % Helium-leak-tested
- Assembly in cleanroom class ISO 5.0
- Approved for the use with oxygen up to 250 bar
- 2 versions: Inlet (gas cylinder) on the right or on the left side (process gas valve is always behind)
