ASCO 291 Series High-Pressure 5000 psi CNG Solenoid Valve

Brand: ASCO

The ASCO Series 291 line of high-pressure solenoid valves is designed specifically for compressed natural gas dispensing equipment.

The rugged stainless steel piston type valve is built to withstand pressure ratings of over 5,000 psi.

The 291 Series high-flow design allows fast CNG dispensing and reduced vehicle fill times.

Features
  • Standard explosion-proof and watertight coil permits use in Class I, Division 1 hazardous locations
  • Wide ambient temperature range of -40° F to 158° F (-40° C to 70° C) is suitable for extreme conditions
  • PEEK piston provides tight sealing and durable operation
  • Available in 3/8, 1/2 and 1 -inch pipe sizes and ISO, NPT or SAE threaded ports
  • High flow design with Cv up to 8.8 (Kv 7.6) for rapid vehicle filling
  • Mountable in any position for convenient installation
  • Optional three- and six-station manifolds save space, reduce leakage paths, and cut
