ASCO HV426 Series Gas Shut-Off Valves

Brand: ASCO
The ASCO HV426 Series low temperature stainless steel gas shutoff valves are designed for the on-off control of fuel gas in commercial and industrial gas burners in harsh environments Its robust design provides consistent and reliable operation. The valves have resilient soft seating for tight shutoff and require zero minimum pressure differential. Suitable for applications such as tank heaters, line heaters, incinerators and flare stacks.
Features
  • Ambient temperature range of -40° F to 125° F (-40° C to 52° C) for a wide range of applications.
  • Explosion-proof Class I Div I enclosure standard.
  • Maximum operating pressure differential up to 50 psi (3.4 bar).
  • Meets Automatic Gas Valves Z21.21, CSA 6.5 C/I Safety Shutoff standard.
  • Complies with ANSI/ISA-12.27.01.2003 single-seal requirements.
  • Meets the metallurgical requirements of NACE MR-0175.
  • Offered in 1/4", 3/8", 1/2" and 3/4" pipe sizes.
  • Available in 12DC and 24DC voltages.
