ITT Engineered Valves
Dia-Flo Solenoid Valve
Solenoid valves control valve activation by directing air to the pneumatic actuator. They are available in 3-way normally-closed or normally-open models as well as 4-way models for double-acting actuators; two 3-way (3/2) solenoids can be used in place of one 4-way (4/2) solenoid to lock the actuator in its last position on loss of pilot pressure.
Configurations
| 3-way (3/2) normally closed | Used with 3100 fail-open and 3200 fail-close actuators |
|---|---|
| 3-way (3/2) normally open | Available |
| 4-way (4/2) | Used with 3300 series double-acting actuators |
| Dual 3/2 in lieu of 4/2 | Locks actuator in last position on loss of pilot pressure (3300 series) |
| Representative model | Asco Solenoid Valve |
