Features
- High flow/high-pressure bodies with manual reset to prevent inadvertent valve start-up
- Once tripped, can only be manually reset
- Electrically Tripped (trips when energized), No Voltage Release (trips when de-energized), or Free Handle constructions
- Available for Latched Open or Latched Closed operation
- Ideal for controlling critical processes
- Some constructions can control aggressive fluids, including steam
- Intrinsically Safe constructions are available
Nominal Ambient Temp. Ranges
-20 ̊F to 104 ̊F (-29 ̊C to 40 ̊C)
Approvals
CSA certified. Some constructions meet shock and vibration ISA S71.03C2.
Operation Alternatives
Electrically Tripped – Valves move to latched position when the solenoid is de-energized, trips when they receive a continuous or momentary (at least 0.3 seconds) electrical signal. When tripped, they can be manually cycled open/closed, but must be reset when the solenoid has once again been de-energized.
No Voltage Release – Valves move to latched position when the solenoid is energized, trips when de-energized. When tripped, they can be manually cycled open/closed, but must be reset when the solenoid has once again been energized.
Free Handle – Valves move to latched position when
the solenoid is energized, trips when de-energized.
They cannot be manally cycled open/closed when
de-energized. They can be manually cycled open/
closed or reset only when energized.
