Drip Zone Control Kit - Maintenance

Products: 
PGV

PCZ/ACZ Drip Control Zone Kits: These pre-assembled kits bring together the popular PGV valve with both a filter and a pressure regulator, providing you with a complete control zone. The PGV valve features high-grade material construction, including a bonnet made of reinforced glass-filled nylon. The kit also includes a stainless steel filter screen, flush cap, and pressure regulator to maintain a consistent 25 or 40 PSI. To save both time and labor, use the ACZ kit to meet your anti-siphon needs.

In this support section, we include the following topics:

  1. Installing the valve
  2. Electrical Connection
  3. Manual Operation
  4. Adjustment of Flow Control
  5. Filter Maintenance
Installing the Valve
  1. Flush the line thoroughly before installation to clean out any debris.
  2. Use only Teflon paste or tape on all threaded valves to pipe connections. Note: Do not use Pipe Dope or solvent cement on threaded connections. After applying the paste or tape around the male adapter or nipple threads, insert the male adapter or nipple into the valve. Tighten by hand, then using a wrench, turn the male adapter or nipple ½ turn to ensure a good seal. Over tightening of fittings may break the valve.
  3. If using male adapters or a slip version of the ASV, glue the male adapters or valve to the pipe (consult your local codes for type of glue to be used). If using a threaded nipple, use the same procedure as above for the threaded connections on the mainline and downstream piping.
  4. To test the connections for water leaks, turn on the main water supply. The valves may open when first pressurized and will close within 1 minute.
Electrical Connection

All Hunter Industries Valves are supplied with a 24 volt solenoid. Connect the solenoid only to a controller that uses an approved class 2, 24 VAC transformer as a power source via approved direct burial type wire. Valve wires can be buried. All wire splices should be joined using waterproof connectors. Run one common wire to each location to serve all the valves at that location. Note: Allow enough slack in the solenoid wires to enable the removal of the solenoid if future maintenance should be required.

Warning: Do not connect the solenoid leads to 110 VAC house current, serious injury or electrocution could result.

Manual Operation

The valves utilize two manual operation methods–an internal manual bleed and an external manual bleed. To operate the valve manually, choose from either of the following procedures. Turn the solenoid ¼ turn counterclockwise or open the bleed screw ¼ turn. To stop manual operation simply tighten either the solenoid or the bleed screw to its original position. The valve will close within 15 seconds.

Adjustment of Flow Control

Open the valve electrically or manually. With the valve open and the system fully pressurized, turn the flow control handle clockwise until the sprinklers are putting out droplets of water with minimal fogging. The flow is now set for that sprinkler system.

Filter Maintenance

Flushing Assembly:

  1. Remove flush cap on top of the wye filter assembly (fig.1).
  2. Turn zone on electrically or manually at valve for a few seconds to flush filter.

Cleaning Filter:

  1. Remove the WYE filter cap assembly by twisting counter clockwise to access the internal filter screen (fig. 2).
  2. Flush out filter with water and reassemble.
