ASCO HV434 Series Gas Shut-Off Valves
Brand: ASCOThe ASCO Series HV434 is a family of low-temperature, stainless-steel shutoff valves with proof of closure for on-off or gas pilot control of commercial and industrial gas burners in harsh environments.
The valves combine a unique double-disc design with a rugged 303 SST GO™ Switch to provide electrical indication of "closed" position.
Their low-power DC peak-and-hold constructions reduce energy consumption to 0.85 W (hold).
The valves design with large pilot orifice provides consistent and reliable operation.
Suitable for applications such as tank heaters, line heaters, incinerators and flare stacks.
Features- Requires zero minimum pressure differential for robust operation in locations with low supply pressure
- Solenoid operator and proof-of-closure switch have Class I, Div. 1 enclosures for use in hazardous locations
- Wide ambient temperature range of -40° F to 125° F (-40° C to 52° C)
- Maximum operating pressure differential up to 50 psi (3.4 bar)
- Resilient soft seating for tight shutoff
- Complies with ANSI/ISA-12.27.01.2003 single-seal requirements
- Meets the metallurgical requirements of NACE MR0175-2003 (DC only)
- Offered in 1" pipe size
- Available in AC and DC voltages
