Description
These valves are direct operated 3-way normally closed solenoid models. The valves mount directly to a piston or
diaphragm actuator enclosure including process control valves and angle seat valves.
The 3-way valves are offered in anodized aluminum body construction. Valves may be ordered with either DIN or
Conduit integrated coils for ordinary locations. DIN coils with cable gland or conduit connector meet NEMA 4, 4X.
Product Features
The valves comprise a standard locking manual override providing operation without electrical supply.
The valves are offered with the following standard features:
-Direct mounting to valve actuator enclosure without extra fittings.
-AC and DC voltage compatibility for easy coil interchange.
-Small size for a low profile.
-22mm DIN coil for direct mounting in non-explosive environments.
-DIN coils UL Recognized, CSA Approved.
-Standard Fluid temperature 14°F (-10°C) to 122°F (50°C).
-Standard Class F DIN or Conduit coils to meet application needs.
Principles of Operation
3-Way Normally Closed Valves
Solenoid de-energized: Pressure is connected to inlet port (#1) and is blocked by the plunger seal pressing against
the body orifice allowing the actuator to exhaust through the valve exhaust port (#3).
Solenoid Energized: The plunger is lifted off the orifice allowing flow though the valve for actuator functioning.
NOTE: No minimum operating pressure is required. Energizing the coil creates a magnetic force sufficient to move
the plunger within the sleeve assembly allowing flow from the inlet port to the outlet port.
MANUAL OVERRIDE
Manual override - The unit is shipped with a standard latching manual override. To engage the manual stem, turn the
slotted stem clockwise 1/4 turn for continuous flow through the valve (to the #1 position stamped on valve). The valve
will remain in the position as when the solenoid is energized. To disengage the manual stem and return the valve to
the de-energized position, turn the stem counterclockwise 1/4 turn (to the #0 position) allowing the override stem to
disengage and return to its original position thereby stopping flow through the valve. The manual override operator
allows manual operation when desired or during an electrical power outage.
WARNING: For valve to operate electrically, the manual override stem must be fully disengaged.
Fluid Codes
Listed below are the common fluid codes The codes for the approved fluids for use with each valve are printed on
the outside of the individual packaging.
CODE FLUID
A - Air or non-toxic, nonflammable gases
For the maximum fluid temperatures, as well as valve ambient temperature limitations, check the valve part number
on the nameplate and refer to the Banjo Valve bulletin.
Installation Instructions
Prior to installing the solenoid valve, depressurize the pipes and clean them internally to avoid particles entering
the system (tape sealant, thread compound). The valves may be mounted in any position.
Mounting position and pressure limits:
Valve with DIN or Conduit Coil:
The valve is mounted directly to the actuator by screwing the banjo bolt directly into actuator inlet port and is designed
to operate in any position. Torque banjo bolt to 35 to 45 in-lbs (4 to 5 Nm). Do not use the sleeve or enclosure as
a lever when applying torque.
Line pressure, voltage and frequency must conform to nameplate rating. Allow adequate clearance above valve for
removal of coil.
Valve Piping: Correctly support and align pipes to prevent mechanical strain on the valve. Connect line pressure to
the inlet port (see dimensional drawing, port 1). Use of tape sealant, thread compound or sealants is permissible, but
should be applied sparingly to male pipe threads only. To avoid damage to the equipment, DO NOT OVERTIGHTEN
pipe connections.
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. If filtration is used, install the filter on the inlet side as close to
the valve as possible. Clean the filter periodically depending on service conditions.
Lubrication: Lubrication is not required although line lubrication will increase valve life.
ELECTRICAL CONNECTIONS
General Recommendations and Safety Precautions
-Electrical connection must be made by qualified personnel using standard electrical practices in
compliance with local authorities and the National Electrical Code.
-Depending on the voltage, electrical components must be grounded according to local standards and
regulations
-The valves are designed for continuous duty operation. To prevent the risk of personal injury, do not
touch the solenoid operator which can become hot under normal operating conditions.
-The solenoid coil must be assembled to the valve sleeve operator for proper valve operation. Failure to
assemble the coil to the valve before applying system voltage will permanently damage the coil
within a short period of time.
-The electrical supply must conform to the nameplate rating.

ELECTRICAL CONNECTIONS (continued)
WARNING:Turn off electrical power before connecting the valve to the power source.
If the coil assembly is located in an inconvenient orientation, it may be reoriented to facilitate installation. Loosen coil
assembly nut, rotate coil assembly to the desired position, and then retighten the nut with an input torque of 4.0 to 5.0
in-lbs. [0,5 Nm].
DIN Coil (ND1) and various cable option terminations: Electrical connection is made with detachable DIN 43650
B plug connector for cable diameters of 6-8mm (Pg9), rotatable by 180° increments (3 pins: 2 + earth ground pin).
Loosen connector screw and remove plastic connector from DIN coil. Do not remove the gasket from the DIN spades
on the coil. Separate the plastic block from the connector housing with a small screwdriver to expose the electrical
terminations. Feed the lead wires through the plastic connector and attach them to the appropriate screw terminal.
Snap the plastic block back into place inside the connector housing. Place the gasket over the DIN spades on the
coil and press the DIN connetor and coil together. Secure the DIN connector to the coil using the mounting screw
provided.
Slide o-ring over and down the sleeve assembly until the o-ring rests on the valve body. Slide the DIN coil over the
valve sleeve. Affix nut to sleeve and tighten between 4.0 to 5.0 in-lbs. [0,5 Nm] torque.
Conduit Coil (NC1) with 1/2” NPT connection: Integrated conduit coils for ordinary locations. Use suitable
electrical cabling and conduit materials and components meeting applicable NEMA recommendations.
Coil / 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 Banjo Valve bulletin to determine the maximum temperatures.
MAINTENANCE
Prior to any maintenance work, switch off power supply and de-pressurize system to prevent the risk of personal
injury or damage to equipment.
•Preventive maintenance
Avoid obstruction of exhaust port when it is not connected or protect it with a cap.
•Cleaning
Maintenance of the valve depends on the operating conditions. Depending on service conditions, filtration may be
required to prevent or minimize dirt or foreign material in the media that could cause excessive leakage, wear, or in
exceptional cases, malfunction.
The valve operator assembly (valve tube) is staked into the valve body and cannot be removed without damaging the
valve. Therefore, valve disassembly should not be attempted.

TROUBLE SHOOTING
Symptom Procedure
1. Valve fails to operate or is sluggish. 1. Check electrical supply with voltmeter. Voltage must agree
with coil rating.
2. If supply voltage too low, locate and correct cause of low
voltage. Should exceed 85% of rated voltage.
3. Check coil with ohmmeter for shorted or open coil. Replace
coil if defective.
4. Clean out extraneous matter in valve ports.
5. Replace valve if steps 1 to 4 do not solve faulty condition.
2. Valve coil burn-out. 1. Continuous high voltage greater than 10% of rated voltage
could result in coil failure. Locate and correct cause of high
voltage.
2. Check electrical wiring installation.
3. Valve located in high ambient temperature. Ventilate or isolate
area from high temperatures. May require valve relocation to
lower temperature area.
4. Replace coil if defective.
3. Valve fails to close (normally closed valve) or
internal fluid leakage occurs when valve should
be closed.
1. Make sure manual override stem is not engaged by turning
counter clockwise direction ¼ turn to the #0 position.
2. Apply air to ports to clean out potential extraneous matter.
3. With coil de-energized, check power at coil wires. Power
should be off. If power is present, correct faulty contacts or
wiring.
4. Replace valve if steps 1 to 3 do not solve faulty condition.
4. External leakage at sleeve flange to body
joint.
1. Through repeated high cycling use, if the valve develops an
external leakage point at the sleeve flange to body interface,
replace valve.
