ASCO 284 Solenoid Valves – 2 Way Pinch Valve (Highly Corrosive Fluids)

ASCO 284 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 284 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 284 solenoid valves are part of the ASCO Red Hat range of valves.

  • Manufacturer : ASCO
  • Product : Solenoid Valve
  • Type : Pinch
  • Series : ASCO 284
  • Valve Body : Anodized Aluminum
  • Valve Voltage : 12, 24 VDC +10%, -5%
  • Flow Control Media : Air:Inert Gas, Water, Oil, Liquids – corrosively aggressive media
  • Valve Function : Normally Closed, Normally Opened  –  2 Way: 2/2

NC = Normally Closed Valve

NO = Normally Opened Valve


  • Large open gap for high flow and handling of particulate media
  • Zero dead volume prevents cross-contamination
  • Electrical connections can be kept separate from fluid area via built-in panel mount bracket
  • Built-in manual operator for easy tubing change out and testing
  • Removable/Rotatable coil for easy service and installation

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 – 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.
