4 Zone 1” Manifold Assembly with 3/4" Control Valve (18 VDC) and Flow Control

4 Zone 1” Manifold Assembly with 3/4 in.  Control Valve (18 VDC) and Flow Control

The 4 zone valve manifold is assembled with 4, 3/4" DC in-line valves with flow control. The four 3/4" in line valves include flow control and 18-VDC solenoid with manual bleed. This DC valve manifold has a 1” FNPT swivel inlet with 3/4" outlet and is used with our model C035 and C038 six-station battery operated controllers. The manifold has quick connection swivel fittings with "O" rings for easy and quick installation. The unit features include easy maintenance of the unit and no tools or glue required in the installation. Large swivel cap allows for easy assembly of the swivel fitting inlet into a 1” MNPT male pipe thread, and provides the ability to maintain, repair and add additional valves for above or below grade installation.

Part #: VA031

The 4 zone valve manifold can be used as a building block for a four zones irrigation system that can be operated by our six station battery operated controller model C035 or C038 with rain sensor connection. The valve manifold configuration includes a 1” swivel female thread with O-ring on the inlet side, a 1” cap ending the manifold, 1” x 3/4” nipples connected into each of the 1” swivel manifolds, a 3/4" inline valve with FNPT connected into each nipple assembled together. The valve manifold can be expanded to any number of valves required for an irrigation system within the space inside the valve box.

The 1” manifold features include 18 VDC high flow 3/4" control valves with flow control and manual lever used for on/off and automatic operation, a swivel fitting with a large swivel cap for quick connection and a 1” cap, allowing the user to maintain, repair or add additional valves with no tools or glue.

To make this manifold suitable for a drip irrigation system, add into the 3/4" outlet of each valve a 3/4" filter with 155-mesh, model F303. To the filter connect a 25-PSI pressure regulator model A014, and to the pressure regulator connect a 3/4" swivel adapter model LF011. Into the swivel adapter connect the drip tubing with .700 OD.

If used for a drip system the 3 valve assembly can have up to 12 GPM (720 GPH) per each valve. If each valve is used only with one lateral of 1/2" drip tubing, the maximum flow per a lateral is 220 GPH and if used with a tee, the total flow rate is up to 440 GPH

Installation for Valve Manifolds

Example: A valve manifold starting from a 1” PVC pipe:

1.      Glue to the PVC pipe a PVC adapter with 1” MPT

2.      Connect a swivel manifold with 1, 2, 3 or 4 outlets depending on the number of valves in the manifold.

3.      To the outlet side of the valve with the swivel connect a PVC male adapter

4.      Glue the PVC pipe to the male adapter

5.      Turn the water on and flush the line

6.      Close the end of the manifold using the end cap (model SWF006, sold separately)

7.      Pressurize the system and make sure that water is not leaking from the unit or any part along the line. Test the assembly manually and then automatically via the controller, and then program the controller.

Note: Make sure that the water flow direction matches for each component, if any is in line with the water flow. Use Teflon Tape only with the PVC male adapter and make sure to remove all Teflon tape excess.
