4-in-1 Drip Irrigation
Valve Instructions

Key Features

1″ Threaded Inlet—Connects to water source
Bleed Lever—Manually turns valve on and off
200 Mesh Filter—Ideal filtering for drip systems
Flush Port—Flushes debris from filter
1/2″ Drip Tubing Adapter—Fits 1/2″ (.630-.710) Drip Tubing
Jar-Top Lids—Easy to service valve and filter
30 PSI Internal Pressure Regulator

Important Guidelines

For outdoor use with cold water only.
Check local codes for installation requirements.
If static water pressure exceeds 80 PSI, a pressure regulator
should be installed on the main sprinkler line.
Warning: DO NOT use pipe dope on threads, use thread seal tape.
Pressure test all water lines and electrically test all timer connections before covering pipe and timer control wire.
Place the manifold so that water drains away from the house.
Protect the 4-in-1 Valve with an valve box and place gravel under the valves for drainage.

Installation Instructions

Attaching the Valves
Apply thread seal tape generously on both male threaded ends and hand tighten the Drip Tubing Adapter on the male threaded outlet (note the arrow for water flow direction). The use of a union at the inlet of each valve will allow for easy valve maintenance. Install a 1″ female threaded PVC adapter on the inlet side and connect it to the water source (see fig. 1).
Important: Do not over-tighten or use pipe joint compound.
Attaching Drip Tubing
Slide tubing into adapter until 1” of the tubing is inserted in the fitting (see figure 2).
Note: The drip tubing adapter fits 1/2” distribution tubing from .630 OD to .710 OD.
Running the Wire
With the power off, connect the valves to an Orbit® sprinkler timer or a residential standard 24-volt sprinkler timer. Use a multicolored, multistrand jacketed sprinkler wire. Be sure the wire has at least one more strand than the number of valves in the manifold. Trench and run the wire to the valves. It is recommended, in areas that you will be frequently digging, that you use a section of PVC pipe as a protective covering.
Wiring the Valve(s)
Attach a colored wire to one valve wire on the solenoid and a common wire to the other wire on the solenoid. It doesn’t matter which solenoid wire you use as the common. Attach the colored wires to the corresponding zone terminal in the timer and the common wire to the common connection in the timer. Use standard sprinkler wire (20 gauge) for distances less than 800 feet and 18 gauge wire for over 800 feet. Use an Orbit® Grease Cap and Wire Nut at each valve connection (see figure 3). Also waterproof any splices made along the run.| Orbit®

Close the Sprinkler Valves
Make sure the bleed lever is rotated clockwise to OFF.
Test the System
After all pipe and fittings have been installed (allowing sufficient time for PVC glued joints to dry—24 hours), turn the water supply on and check for leaks with the valves closed. The valves may come on momentarily while initially pressurizing the line, but will shut off in a few moments.
Open Valves
Turn the manual bleed lever counter-clockwise to manually open the valve. Check the downstream pipe and fittings for leaks. Now close the bleed lever. The valve will shut off in a few moments. The system is now ready to be controlled electrically from the timer or manually by opening the internal manual bleed lever. (Caution: Frequent manual operation of the valve using the internal manual bleed lever is not recommended. This type of manual operation is for trouble-shooting and occasional use.)

Parts Listing 8. Draining
In freezing areas, the valves and lines will need to be drained. Refer to the Orbit® Layout Guide or your local dealer to recommend proper drain points. To ensure the electric valves are completely drained in the fall, turn off the main sprinkler shut-off valve and electrically run each valve dry for a few minutes. Turn the timer to the OFF position until next spring.
9. Filter Cleaning Service
Your 4-in-1 Drip valve filter will require routine servicing.
Monthly
Use the flush port to clean large debris from the filter (adjust frequency based on your water condition). Before flushing ensure that the timer is in the OFF position. Next, remove the flush cap and attach a garden hose to the filter housing. Rotate the bleed lever counter-clockwise to manually open the valve and let the water run for 30 seconds. Turn the bleed lever clockwise to close the valve and replace the flush cap.
Annually
Removing fine debris from the filter. With your timer in the OFF position, remove the filter housing by unscrewing the housing ring. Gently remove the filter and flush with clean water. Ensuring that all four o-rings are in place. (see figure 3). Replace housing and hand tighten the housing ring.

Troubleshooting

It is rare that your Orbit® low voltage electric valve will not operate as it should. If you do have any problems, try the following solutions.
The valve will not open electrically
First, run the valve manually by opening the manual bleed lever (turn counterclockwise).
Close the manual bleed lever when manual test is complete.
The valve is installed incorrectly Make sure that the arrows are in the direction of water flow.
Wiring is incorrect
Make sure that the arrows are in the direction of water flow. Check wiring at the valve and at the timer with the instructions. Check to see that timer is working properly.
There is debris in the port hole
Turn off water. Remove the solenoid. Push a wire or large paper clip down through the round port hole working it up and down to free any debris. Be sure the plunger and o-ring are in place when reassembling.
Defective solenoid
Turn off water. Unscrew the solenoid and replace with one from a working valve. If the valve works, replace the solenoid. Be sure the plunger and o-ring are in place when reassembling.
Solenoid plunger is stuck
Turn off water. Remove the solenoid and clean out sand and debris. Be sure the plunger and o-ring are in place when reassembling.
The valve will not close
The valve is installed incorrectly Make sure that the arrows are in the direction of water flow
Solenoid plunger is stuck
Turn off water. Remove the solenoid and clean out sand and debris. Be sure the plunger and o-ring are in place when reassembling.
Rock or debris is between the washer and the valve seat
Turn off water. Remove valve lid and diaphragm assembly and clean the interior of the valve.
Diaphragm has ruptured
Turn off water. Remove the lid and inspect the diaphragm for tears. Replace the diaphragm assembly if torn.
External valve leaks
PVC fittings going to valve installed incorrectly
Use thread seal tape generously on threads and tighten firmly. Do not over tighten.
Pressure is too high
Install a pressure regulator upstream of the valve and set at about 80 PSI (5.5 bars).
Leaking below solenoid
Turn off water. Tighten solenoid.
