ASCO 310 Solenoid Valves – SIL 3 Explosion Proof & Watertight Manual Reset Valve

ASCO 310 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 310 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 310 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO 310 solenoid valves feature high flow and high pressure bodies with manual reset in order to prevent inadvertent valve start-up.

Once tripped, the ASCO 310 solenoid valve can only be manually reset making it ideal for controlling critical processes.

The ASCO 310 solenoid valves are available for latched open or latched closed operation and some constructions can be used for the control of aggressive fluids including steam.

ASCO 310 Solenoid Valves – Product Benefits

Further benefits of the ASCO 310 solenoid valves include:

  • Electrically Tripped (trips when energized), No Voltage Release (trips when de-energized), or Free Handle constructions
  • Intrinsically Safe constructions are available

ASCO 310 Solenoid Valves – Operation Alternatives

Electrically tripped – The valves move to the latched position when the solenoid is de-energised and trips when receiving a continuous or momentary (at least 0.3 seconds) electrical signal. When tripped, the ASCO 310 valve can be manually cycled open/closed, however they must be reset when the solenoid has been de-energised again.

No voltage release – Valves moved to the latched position when the solenoid has been energised trips when de-energised. When the valve has been tripped they can be manually cycled open/closed, however must be reset once the solenoid has been energised again.

Free handle – The valve is moved to the latch position when the solenoid is energised and trips when it becomes de-energised. They can not be manually cycled open/closed when de-energised. The valves can be manually cycled open/closed or reset only when energised.

HAZARDOUS AREA LOCATIONS CERTIFICATION

ASCO 310 valves are CSA certified solenoid valves. T&D distribute the complete range of hazardous area solenoid valves manufactured by ASCO.

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 – 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.
