JTV/JTVF male x male (MM) and male x barb (MB) are not recommended for flows exceeding 30 GPM (6,8 m

/h or 1,9 I/s).

For flows below 3 GPM (0,75 m
3
/h or 0,21 I/s), or any Landscape Drip application, use RBY-100-200MX filter installed
upstream.
Loosen solendoid

turn and then tighten the solenoid completely (
1
⁄

turn beyond hand
tight). Use the solenoid handle, which is specifically designed to shut the valve off completely
and keep it from “weeping.” Also tighten the bleed screw and bonnet.
Use the external bleed screw to flush the valve. If performance does not improve,
turn off water. Unscrew bonnet and remove. Remove diaphragm and clean it in clear water.
Reinstall diaphragm and bonnet. If necessary, replace the diaphragm with kit number
231771.
Check water source, controller power, and flow control to make sure they are open.
Turn off water. Unscrew bonnet and remove. Inspect body for debris. If filter is missing from
diaphragm, replace diaphragm with kit number 231771.
Turn off water. Remove solenoid and replace with a known working solenoid. If the valve still
won’t open, replace the solenoid.
Check system water pressure. If pressure is greater than 80 psi (5,5 bars), install a
pressure regulator on the line before the valve to reduce water pressure.
Check to ensure the yellow o-ring inside the union connector is in place. If lost, replace with
part #231771. If necessary, tighten connectors further.
Check for blocked dump port (especially slip
x slip). Remove bonnet. Remove diaphragm.
Insert a probe (flag marker wire or paper
clip) as shown.
NOTE
: During winter shutdown, drain the system to protect JTV valves
from freezing. Failure to properly drain lines may damage the
valves. Be sure to comply with all local guidelines.

(Threaded non-union models only)
To make a watertight seal, wrap 1

⁄

to 2 turns of
Teflon tape around the threads on two male x slip
adapters (A) or on the male threads of the valve
(B; MM and MB models)
(Threaded union models only)
To make a watertight seal, use male threaded adapters
with a smooth, flat face for the o-ring to seal against.
CAUTION
: Do not use teflon tape for union valve
models.
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 lrrigation Design Guide
. Refer to
local building codes for additional requirements.
3. Flush the system thoroughly until the water from the
submain runs clear.
Connect Adapters to Valve
5. Screw the adapters into the valve water ports and hand
tighten.
Carefully tighten the adapters one to two additional
turns past hand-tight.
CAUTION
: Do not over-tighten the adapters. You may
damage the valve or block the exit ports.
Connect Valve to Pipes
7. Carefully apply a small amount of solvent cement to the
inside of the adapter (A, threaded connector) or valve
inlet port (B, slip connector). Apply a small amount of
cement to the outside of the water supply pipe. Then
attach the valve to the pipe. The valve solenoid
MUST
be on the downstream side (C).
CAUTION
: Use only a small amount of solvent
cement. Excess cement can damage the valve
internally.
8. Cement the lateral pipe to the adapter (A, threaded
connector) or valve outlet port (B, slip connector), as
described in step 7.
9. To attach an MB model valve to low-density
polyethylene pipe, cut the pipe square and clean. Slip
one or two clamps over the poly pipe.
If necessary, carefully heat the poly pipe for easier
installation. Slip the poly pipe completely over the barb
(A). Then clamp (B) the pipe securely to the barb for a
leak-proof seal.
Connect Valve Wires
10. Select a wire gauge that meets electrical specifications.
Multi-strand, direct-burial wire is recommended. Refer
to local building codes for additional requirements.
11. 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.
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.
12. 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.
Operate Valve Manually
13 To open the internal bleed, turn the solenoid handle (A)
counterclockwise
1
⁄
4
to
1
⁄
2
turn. Be 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.”
To reduce flow (JTVF models only), turn the flow
control stem (B) clockwise. Use your fingers or a slot-
head screwdriver. To increase flow, turn the stem
counterclockwise.
To open the external bleed, turn the bleed screw (C)
counterclockwise two turns.
Use the external bleed to
flush the valve when you first start the system
. Turn the
screw clockwise to close it.
