Low Power valves minimize temperature rise and power draw allowing the user to reduce wiring and operate these DC valves

directly off of computer control. Intrinsically Safe valves are for use in an inherently safe system which will not ignite an

explosive atmosphere.

.

Three way （3/2） Normally Closed and Universal operations

.

Four way, four and five port （4/2 and 5/2） operation

.

Size range of 1/4" to 1/2"

Intrinsically Safe/Low Power

Valve and pilot need to be ordered as separate line items. Order one pilot, 19000006-120/60, per valve, 54202017.

Manual Reset valves use manual reset assemblies in conjunction with the solenoid in order to prevent inadvertent valve

startup in their designed failure modes.

No Voltage Release valves can be latched by moving the lever to the latched position when the solenoid is energized, the

valve trips when the solenoid is de-energized. When tripped the valve can be manually cycled open/closed but the solenoid

must be energized to re-latch.

Electrically Tripped valves can be latched when the lever is moved to the latched position and the solenoid is de-energized.

The valve trips when the solenoid is energized by a continuous or momentary

（0.3 seconds minimum） electrical signal.

Three way （3/2） Universal （can function as NC, NO, diverter of one fluid, or selector of 2 fluids） operation
