ASCO 327 SOLENOID VALVES
- The 327 solenoid valves are certified according to IEC 61508 Functional Safety data and have SIL-3 capability (Exida certification)
- These ASCO 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
- 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
