Before Installation
1 Make sure you have sufficient water supply,
pressure, and flow. Connect pipes to primary
water source.
2
Install master valves, pressure regulators, and
backflow preventers as needed. For system
design information, refer to the Rain Bird
Connect Adapters to Valve
4
To make a watertight seal, wrap 2 to 4 turns of
Teflon tape around the threads on two male x
slip adapters (A).
5
Screw the adapters into the valve water ports
and hand tighten.

3
Flush the system thoroughly until the water from
the main runs clear.
Carefully tighten the adapters one to two
additional turns past hand-tight.
CAUTION: Do not overtighten the adapters.
You may damage the valve or block
the exit ports.
Connect Valve to Pipes
6
Carefully apply a small amount of solvent
cement to the inside of the adapter (A). Apply a
small amount of cement to the outside of the
water supply pipe. Then attach the valve to the
pipe. The valve solenoid (B) MUST be on the
downstream side.
Connect Valve Wires
8
Select a wire gauge that meets electrical
specifications. Multi-strand, direct-burial wire is
recommended. Refer to local building codes for
additional requirements.
9
Use a watertight connector to connect one lead
on each valve to a common wire (A). Either lead
may be used. All valves on the same controller
can share the same common wire.
Operate Valve Manually
11
To open the internal bleed, turn the solenoid
handle (A) counterclockwise 1 ⁄ to 1 ⁄ turn. Be
4 2
sure to re-tighten the solenoid completely.
Always use the solenoid handle, which is
designed to shut the valve off completely and
keep it from "weeping."
Components
Illustration 12 shows the following components of
the JTV valve:
A. Solenoid E. Body
B. O-ring F. Bleed screw
C. Bonnet G. Spring
D. Diaphragm H. Filter
CAUTION: Use only a small amount of solvent
cement. Excess cement can
damage the valve internally.
7 Cement the lateral pipe to the adapter (A) as
described in step 6.
Use a watertight connector to connect the
second lead on each valve to a power wire (B).
Each power wire must be run separately to the
controller.
10
Connect the shared common wire (A) to the
common terminal on the controller. Connect one
power wire from each valve (B) to a station
terminal on the controller.
To open the external bleed, turn the bleed screw
(B) counterclockwise two turns. Use the external
bleed to flush the valve when you first start the
system. Turn the screw clockwise to close it.
