INSTALLATION, OPERATING & MAINTENANGE INSTRUCTIONS
2-WAY N.C., N.O., AND D. P. SOLENOID VALVE
119,,, 1/4",AND 3lg" NPT
VALVE TYPES: 71215, 71216, 7121V, T1Z}S, 71235 C€
DESCRIPTION
These valves are 2-way, direct operated models. They are
available in normally closed (N.C.), normally open (N.O.), anO
dual purpose (D.p.) versions. The 11215, Z1Zj6, T121V,
71295, and 7123s are offered in stainless steer donstruction.
Valves may be ordered with either NEMA 2,4,4X integrated
coils for ordinary locations or NEMA 4, 4X, 7, and g for
hazardous locations: Divisions I and ll; Class l, Groups A, B,
C, and D; Class ll, Groups E, F, and G. Additional solenoid
coils and enclosures are offered as described in our catalog.
PRINCIPLES OF OPERATION
Normally closed type: 71215
De-energized: Pressure is connected to porl 2 and is
blocked by the plunger seal pressing on the body orifice.
Energized: The plunger is lifted off the orifice allowing flow
through the valvg (Port 2 to 1). On bodies withoul port
markings, the direction of frow is indicated by an arrow on the
body.
Normally closed type: 7121V.
De-energized: Pressure is connected to port 1 and is
blocked by the plunger seal pressing on the body orifice.
Energized: Plunger is lifted off the orifice allowing flow
through valve (Port 1 to 2). On bodies without port maikings,
the direction of flow is indicated by an arrow on the body.
Normally closed, high pressure type: 71216
De-energized: These valves are direct acting, but utilize an
armature, conically shaped pilot, and pilot guide in lieu of a
plunger. Pressure is connected to port 2 and flows up
through the pilot guide, surrounding the armature, where it is
blocked at the orifice by the pilot.
E nergized:. Thearmature -oeelerate-@e

flow to occur from Porl2 to Port 1.
Normally open type: 7129s
De-energized: Pressure is connected to port 2 and fluid is
free to flow out Port 3.
Energized: The plunger moves causing the seal to block the
normally open orifice. Flow between ports 2 and 3 is then
stopped.
Dual purpose type: 71235
De-energized: Pressure may be connected to either port 1
or Port 2, depending on the desired direction of flow.
Pressure is blocked in either direction by the prunger sear
pressing against the body orifice.
Energized: Plunger is lifted off the orifice allowing flow
through valve. Once again, flow is permitted in either
direction depending upon the supply pressure connection.
FLUID CODES
Listed below are the codes utirized by Underwriters
Laboratories (uL) and the canadian standards Association
(csA) for various common fluids. The codes for those fluids
that are approved or certified by the agencies for use with

I NSTALLATION INSTRUCTIONg
Mounting position and pressure limits: Valves can be
mounted directly on piping or by using the two (2) #10-32 NF
threaded holes in the bottom of thJ varve body. Mounting
brackets are avairabre for those varves having #10-32 NF
mounting holes and may be ordered separately.
The7121V,71215,11235, and712gS valves ire designed to
be multi-poised and so wiil perform properry when ,no..i.t"d in
any position. However, for optimum life and performance the
valves should be mounted verticaily upright so as to minimize
wear and reduce the possibility of foreign matter
accumulating inside the sleeve area. The 21216 vllves must

always be mounted vertically upright to ensure proper
operation.
Line pressure must conform to nameplate rating.
Piping: Remove protective closures from the ports. Connect
line pressure to the inlet port. Use of Teflon tape, thread
compound or sealants is permissible, but should be applied
sparingly to male pipe threads only. Loctite primer #764 and
pipe sealant #567 are recommended when using stainless
steel fittings with stainless steel valve bodies.
GAUTION: Do not allow foreign particles, Teflon tape, or
thread compound to enter valve. Tightening torque should
not exceed the following values for each port size: 1/8" NPT -
100 in-lbs., 1/4" NPT - 175 in-lbs., 3/8" NPT - 225 inJbs' Do
not use the sleeve or enclosure as a lever when applying
torque.
Media filtration: Normally filtration is not required, but dirt or
foreign material in the media may cause excessive leakage,
wear, or in exceptional cases, malfunction. lf filtration is
used, installthe filter on the inlet side as close to the valvp as
possible. clean periodically depending on service conditions.
Lubrication: Lubrication is not required although air line
lubrication will substantially increase valve. life.
GAUTION: Valves which have sea/s or other components
made trom ethylene propytene rubber must not be exposed to
petroleum based lubricants or other hydrocarbons.
Electrical connection: Electrical supply must conform to
nameplate rating. Connect coil leads or terminals to the
electrical circuit using standard electrical practices in
compliance with local authorities and the National Electrical
Code.
WARNING : Valves t6 be instdllecl in Hdzardous Locationi,
must be outfitted with Hazardous Location coils only. verify
nameplate data and coil part number before installing the
valve.
wARNING: Turn off electrical power before connecting the
valve to the Power source'
lf the coil assembly is located in an inconvenient orientation, it
may be reoriented to facilitate installation. Loosen coil
assembly nut, rotate coil assembly to desired position, then

Goil/enclosure temperature: standard valves are supplied
with coils designed for continuous duty service. Normal free
space must be provided for proper ventilation. when the coil
is energized continuously for long periods of time, the coil
assembly will become hot. The coil is designed to operate
permanently under these conditions. Any excessive heating
will be indicated by smoking and/or odor of burning coil
insulation.
For the maximum valve ambient conditions, as well as the
fluid temperatures, check the valve part number on the
nameplate and refer to the catalog'
MAINTENANCE
Note: Depending on service conditions, fluid being used,
filtration, and lubrication, it may be required to periodically
clean and/or replace worn components. See Disassembly
lnstructions.
CAUTION: Do not expose plastic or elastomeric materials to
mV tVW of commerciat cteaning fluid. Parts should be
cleaned with a mild soap and water solution.
DISASSEM BLY INSTRUCTIONS
WARWI]|O: Depressurize sysfem and turn off electrical
powe@ingrePair.
The N.C. and D.P. valves need not be removed from the line'
lf the pipe connection to N.O. valves is made to the sleeve
port, disconnect piping prior to commencing repair.
To remove the coil assemblY:
Normally Closed and Dual Purpose Valves I For both
ordinary and hazardous location constructions, unscrew the
nut on the top of the coil assembly. The wave washer and
coil assembly can now be removed'
Normally Open Valves - First unscrew the sleeve adapter
and remove. Then follow the same instructions as for
normally closed and dual purpose valves stated above'
To disassemble the pressure vessel:
CAUTION: tf the sleeve assembly does not have a hex style
flange, do not use a pipe wrench directly on the sleeve'
lnstead, use a Skinner LJ99-011 wrench nutto remove and
install the sleeve assemblY.
Normally Glosed, Normally Open, and Dual Purpose
Valves -
Slide the Skinner U99-011 wrench nut over the sleeve tube.
To unscrew the sleeve assembly, mate the wrench nut to the
sleeve flange and turn the wrench nut. The plunger, return
spring, and flange seal may now be removed. The 7121V
valves contain a hex style flange in the sleeve assembly' ln
this case, a wrench may be applied directly to the hex flange
in order to loosen the sleeve assembly.
Manual override removal (where applicable) - Extract the
override retention pin. Rotate override stem until it is free to

remove. Withdraw override lever, or the spring and roller in
the case of larger size valves (1/8" orifice diameter or
greater).
Replacement Parts: When ordering replacement parts kits,
specify valve number and voltage from nameplate. Parts kits
are available for each valve. Parts included in each kit are
marked with an asterask (.). See exploded views.
REASSEMBLY INSTRUCTIONS
WARNING= When replacing coils, valves equipped with
Hazardous Location coils must use Hazardous Location
replacement coils only. Verify nameplate data and coil pari
number before installing the replacement coil.
To reassemble the pressure vessel:
Refer to exploded view drawings. Parts must be replaced in
the order shown.
Assemble manual override (where available) prior to
assembly of sleeve to body. lnsert override lever into body.
