ASCO 256 Solenoid Valves – Oil/Gas Subminiature Shut-Off Valve (2 Way)

ASCO 256 solenoid valves

ASCO 256 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 256 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO 256 solenoid valves are manufactured with compact a design in order to fit in tight spaces and are mountable in any position.

With brass and 316 stainless steel body constructions, typical applications for the ASCO 256 solenoid valves include commercial kitchen and laundry equipment, heating and bottling equipment.

In addition, there is an NSF 61 Annex G and 169 version available for potable water and food service 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 – 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.
