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