ASCO H118 Solenoid Valves – Hydramotor Gas Shutoff Valve (Explosion Proof FM Approved)

ASCO H118 Hydramotor Solenoid Valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO H118 Hydramotor Solenoid Valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO H118 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO H118 solenoid valves are normally closed, 2 way valves with a rugged construction and suitable for general purpose applications.

The ASCO H118 solenoid valves are combination hydramotor actuator and safety shutoff/control gas valves with typical installations including furnaces, dryers, dehydrators, conversion burners and heaters.

The cast iron, globe-type valve body features a soft synthetic seat and integral heavy-duty return spring for tight and certain closure in one second or less upon current interruption.

The self contained, hermetically sealed pull-type electro-hydraulic actuator consists of a motor/pump unit immersed in oil, reducing wear and provides highly reliable operation.

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.
