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 systemdesign information,
Connect Adapters to Valve
4. To make a watertight seal, wrap 1½ to 2 turns of Teflon
4
tape around the threads on two male x slip adapters (A)
or on the male threads of the valve (B; MM and MB
models)
5. Screw the adapters into the valve water ports and hand

tighten.
Connect Valve to Pipes
7. Carefully apply a small amount of solvent cement to the
7
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). For DV-A and DVF-A
models, connect the supply pipe to the bottom
inlet (D).
CAUTION: Use only a small amount of solvent
cement. Excess cement can damage
the valve internally.
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
11
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
13 To open the internal bleed, turn the solenoid handle (A)
13
counterclockwise ¼ to ½ 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 (DVF models only), turn the flow control
stem (B) clockwise. Use your fingers or a slot-head

3. Flush the system thoroughly until the water from the

submain runs clear.

Carefully tighten the adapters one to two additional

CAUTION: Do not over-tighten the adapters. You may
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
9
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.
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
12
terminal on the controller. Connect one power wire
from each valve (B) to a station terminal on the
controller.
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.
damage the valve or block the exit ports.
