Installation & Operation of 2V025-08:
To Connect the Valve Inlet & Outlet:
Connect the inlet & outlet to the valve ports according to the flow
direction arrow marked on the valve
To Install the Coil:
Put the coils on to the armature tube of the valve. Place the lock
washer & nut on to the armature tube. Hand tighten the nut, then
use a wrench to tighten the nut another quarter-turn.
Do not over-tighten the nut, as it may cause the armature tube to
fail prematurely.
To Connect a DIN Coil:
1. Remove the screw from the plastic DIN housing & unplug it from
the DIN coil
2. From the screw opening, push the terminal block out from the
plastic DIN housing.
3. Note the “1”, “2”, and ground “⏚” symbols on the underside of
the DIN enclosure.
4. For DC DIN Coils, connect “1” to your Positive Lead & “2” to
your Negative lead.
5. For AC DIN Coils, connect “1” to your HOT lead, “2” to your
Neutral lead, & “⏚” to your ground if required.
Do not energize the coil without installing it onto the valve or
connect the coil to a different voltage than specified. This will
burn the coil and could create fire hazards.
Safety Note: Standard valves are supplied with continuous duty coils. The
proper class of insulation for the service is indicated on the coil
body. The coil temperature may rise significantly if energized for
extended periods—this is normal. Although the coil is made of
flame-retardant material, misuse of the coil could create fire
hazards & generate smoke and/or a burning odor. If these conditions
are encountered, the coil temperature has risen above safe levels
and the power should be disconnected immediately.
Operation: This valve is a two-way, normally closed, direct-acting valve &
does not require a minimum differential pressure to operate. As
shown in the diagrams below, when the coil is de-energized (left
diagram), the plunger rests on the main orifice & is held in place
by the plunger spring force, sealing the valve. When the coil is
energized (right diagram), the solenoid lifts the plunger & allows
the working medium to flow through the orifice. The working medium
& flow direction are indicated in purple in the diagrams
