HV & HVF VALVES
HV and HVF Series Valves Archives
Before Installation
- Make sure you have sufficient water supply, pressure, and flow. Connect pipes to primary water source.
- Install master valves, pressure regulators, filters, 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.
- Flush the system thoroughly until the water from the submain runs clear.
Connect Adapters to Valve
- To make a watertight seal, wrap 1½ 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)
- 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
-
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 downstreamside (C).
CAUTION: Use only a small amount of solvent cement. Excess cement can damage the valve internally. -
Cement the lateral pipe to the adapter (A, threaded connector) or valve outlet port (B, slip connector), as described in step 7.
-
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
-
Select a wire gauge that meets electrical specifications. Multi-strand, direct-burial wire is recommended. Refer to local building codes for additional requirements.
-
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. -
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 -
To open the internal bleed, turn the solenoid (A) counterclockwise ¼ to½ turn. Be sure to re-tighten the solenoid completely. Do not over-tighten solenoid or use tools to tighten. If valve weeps or does not shut off, look elsewhere for grit or another cause. Always use the solenoid, which is designed to shut the valve off completely and keep it from “weeping.”
To reduce flow (HVF 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.
Operating Ranges
| 100-HV, 100-HVF, 100-HVMM1,100-HVMB1, 100-HV-SS, 100-HVF-SS
---|---
Flow2| 0,2 – 30 GPM
(0,05 – 6,81 m3/h or
0,O1 – 1,90 I/s)
Pressure| 15 – 15O psi
(1 – 10 bar)
- HV/HVF male x male (MM) and male x barb (MB) are not recommended for flows exceeding 30 GPM (6,8 m3 /h or 1,9 I/s).
- For flows below 3 GPM (0,75 m3 /h or 0,21 I/s), or any Landscape Drip application, use 200 mesh filter installed upstream.
Troubleshooting
| Symptom | Solution |
|---|
Valve won’t shut off completely.
Sprinklers “weep.”| Tighten the solenoid completely (V4 turn beyond hand
tight). Use the solenoid, which is specifically designed to shut the valve off
completely and keep it from “weeping.” Also tighten the bleed screw and bonnet
screws.
a Use the external bleed screw to flush the valve. If performance does not
improve, turn off water. Unscrew bonnet screws and remove bonnet. Remove
diaphragm and clean it in dear water. Reinstall diaphragm and bonnet. If
necessary, replace the diaphragm with kit number 231900.
Turn off the water. Remove the solenoid. Clean any dirt or grit from the
solenoid bowl. Replace solenoid. Turn on water. Check for weeping.
Valve won’t open.| Check water source, controller power, and flow control to
make sure they are open.
Turn off water. Unscrew bonnet screws and remove bonnet. Inspect body for
debris. If filter is missing from diaphragm, replace diaphragm with kit number
231900.
Turn off water. Remove solenoid. Carefully insert a small stiff wire in the
hole in the center of the solenoid bowl and shove it into the outlet of the
valve. Do not damage the top lip of the hole in the center of the solenoid
bowl. Remove wire. Replace solenoid.
Turn off water. Remove the solenoid and replace with a known working solenoid.
If the valve still won’t open, replace the original solenoid.
Turn valve on using the External Manual Bleed Screw to remove any air that may
be trapped above the diaphragm. Turn valve off using the External Manual Bleed
Screw.
Valve slams on/off (water hammer).| Check system water pressure. If pressure
is greater than 80 psi (5,5 bar), install a pressure regulator on the line
before the valve to reduce water pressure.
On Flow Control models, turn zone on using the solenoid. Turn down the Flow
Control handle until a drop in system performance is noticed. Back off the
Flow Control only until system performance is restored..
NOTE: During winter shutdown, drain the system to protect HV valves from
freezing. Failure to properly drain lines may damage the valves. Be sure to
comply with all local guidelines.
