Series K37 Cryogenic 2/2-Way Solenoid Valve (NC), Pilot-Operated Flange DN15 – DN50, 0–40 bar

The Type K37 2/2-way force-pilot operated piston valve is designed for neutral gaseous and liquid media and operates at extreme temperatures from -60°C to +80°C. Normally closed (NC) as standard, optionally normally open (NO). The force-pilot design requires no pressure differential and closes by spring force when de-energized. The stainless steel housing (1.4581) and PTFE seals ensure durability and reliable sealing. Available with flange connections DN15 to DN50 (EN 1092-1 Form B1/B2) and a pressure range up to 40 bar. IP65 enclosure and ATEX certification make it suitable for industrial environments.
