ASCO 290 Solenoid Valves – Direct Acting Valve 2 Way NC NO

ASCO 290 Solenoid Valves Direct Acting
ASCO 290 solenoid valves are part of the ASCO Red Hat range of valves.
ASCO 290 solenoid valves consist of 2 way direct acting valves available in normally closed or normally open configurations.
Manufactured for demanding applications, the ASCO 290 solenoid valve can be supplied in straight-through body design made from bronze or stainless steel.
There are many optional features including visual an electrical position indicators or a stroke limiter.
NC = Normally Closed Valve
NO = Normally Open Valve

ASCO SOLENOID VALVES – HAZARDOUS AREA LOCATIONS, safety & standards
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 – hazardous 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.
