A91 Series 2/2-way cryogenic solenoid valve G1/4 – G2 0–40 bar

The Type 91 is a force-pilot operated piston valve for cryogenic liquids and neutral media, designed for temperatures down to -196°C. The valve closes upon de-energization and requires no pressure differential for operation. The housing is available in brass (2.0402) or stainless steel (1.4581 for PN16, 1.4404 for PN50), with PTFE seals for compatibility with aggressive media. Available with weld-on sleeve connections from G1/4 to G2, with pressure ranges up to 16 bar (PN16) or 40 bar (PN50).
