ASCO 327 SOLENOID VALVES

  • ASCO 327 valves are certified according to IEC 61508 Functional Safety data and have SIL-3 capability (Exida certification)
  • The solenoid valves are recommended for pilot applications with high flow, wide pressure ranges and no minimum operating pressure
  • Coils used in metal enclosures have class H insulation materials
  • The core movement is guided to ensure optimal alignment. The special low friction seal accomplishes a balanced construction at the specified temperature and pressure range at minimum power levels
  • Special rider rings eliminate sticking and provide exceptional service life
  • No minimum operating pressure required
  • Pressure can be applied at any port
  • 316L stainless steel construction for highly corrosive atmospheres
  • The ASCO 327 solenoid valves satisfy all relevant EC Directives
  • Manual Operators are optional including an under pressure removable type
  • Environmental NACE compliant and certified vibration resistant in combination with WSCR solenoids

Differential Pressure : 0 – 10 bar (1 bar = 100 kPA)

Response Time : < 100 ms
