ASCO 040 Solenoid Valves – Gas Shutoff Valve 2 Way NC Brass (1/8″ NPT)

ASCO 040 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 040 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 040 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO 040 solenoid valves are 2-way, normally closed valves for gas pilot or main control of commercial and industrial gas burners.

The valves are provided with 1/8″ NPT upstream and downstream pipe taps with plugs for routine testing and are mountable in any position.

The ASCO 040 solenoid valves are ideal for low pressure applications as well as air and vacuum service.

Typical applications include combustion and heating equipment for use in industries such as oil and gas.

ASCO solenoid valves (2-way, 3-way and 4-way type including NAMUR interfaces) control the critical flow of air, gas, water, oil and steam across all industries – hazardousSIL IEC 61508 - Solenoid Valves area solenoid valves are available for Division and Zone classifications.

Class I, Division 2 and Zone 1/Zone 2 approved solenoid valves according to ATEX, IECEx, FM, CSA and UL are available. Flameproof and explosion-proof valves can be specified for potentially explosive atmospheres where there is a presence of flammable liquids, gases or vapours.

ASCO valves improve reliability and performance of safety systems according to IEC 61508, IEC 61511 and Safety Integrity Levels (SIL) – ASCO spool valves with SIL 4 capability are SAEL listed as assessed by Exida and TÜV.
