ASCO 342 Solenoid Valves – Direct Mount Pilot Valve (4 Way Direct Acting)

ASCO 342 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel..

ASCO 342 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 342 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO 342 solenoid valves are direct acting, high flow slide-style valve with no minimum operating pressure differential required to shift valve.

Available with dual or single solenoid operation, the ASCO 342 solenoid valves have an optional flow control to regulate cylinder speed independently and in either direction.

Mechanical detent on dual solenoids holds the last position even after loss of power, pressure or pneumatics.

Typical applications for the ASCO 342 solenoid valves include biofuels, analytical and diagnostic equipment, dust collector systems, heating equipment and refining equipment.

Common industries include oil & gas, power and chemical.

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.
