ASCO 284 solenoid valves are part of the ASCO Red Hat range of valves.
ASCO 284 solenoid valves are part of the ASCO Red Hat range of valves.
NC = Normally Closed Valve
NO = Normally Opened Valve
Typical applications of the ASCO 284 solenoid valves include in medical equipment, analytical instruments, food and industrial applications.
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.
