Automatic AC Valve Assembly for Drip Systems

DIG’s 24VAC Drip Zone Assembly Kit is a complete drip zone unit composed of a 3/4”, 24VAC in-line valve, 3/4” heavy duty filter with a 155 mesh screen, 25 PSI preset pressure regulator and 3/4” FHT swivel adapter with .700 OD. The drip zone provides installation simplicity with reliable performance and an affordable price to start a drip irrigation installation. The assembly kit automates a drip irrigation zone, provides protection to the drip emitters and micro sprinklers from particles that may enter the system, and reduces or regulates the incoming pressure of the water entering the micro irrigation system to the appropriate operating pressure of 25 PSI, which is within the range of recommended operating pressures for a drip irrigation system.

Features

  • All-purpose complete unit includes a 3/4″, 24VAC in-line valve, 3/4” heavy duty filter with a 155 mesh screen, 25 PSI preset pressure regulator and 3/4” FHT swivel adapter with .700 OD.
  • Operates at very low flow from less than 1 gallon per minute up to 12 gallons per minute
  • Constructed of UV-resistant, durable plastic material to withstand the most adverse conditions
  • Can be connected to drip tubing or to pipe thread
  • Compact design to fit smaller valve box
  • The 24VAC high-flow-with-low-pressure-loss valve has internal bleed for manual ON/OFF
  • Compatible with all 24-volt controllers and timers
  • The 24VAC valve’s rugged, reinforced diaphragm provides reliable operation even with contaminated water
  • Includes heavy duty 155 mesh screen filters with large filtration area and low friction loss for long intervals between cleaning
  • The screen filter has excellent resistance to most common chemicals
  • Easy maintenance; the screen can be removed from the filter for easy cleaning
  • Color-coded replacement screens for easy identification are available
  • The 25 PSI preset pressure regulator reduces incoming water pressure to the ideal working pressure for a drip irrigation system

About:

The 24VAC Drip Zone Assembly Kit contains all the parts needed to start a drip irrigation system, including a 24VAC 3/4″ FNPT heavy duty in-line valve, 3/4″ “Y” filter with 155 mesh, and 3/4″ 25 PSI preset pressure regulator (completely assembled). The kit also includes a 3/4” swivel adapter with .700 OD to connect the drip zone kit into drip tubing. This assembly can be used to start a drip irrigation system from a 3/4″ PVC pipe, connecting the 24VAC valve to any AC controller via 18 to 22 AWG gauge electric wire. Use this drip zone kit for a drip irrigation system installation in residential or commercial applications.

Drip irrigation requires clean water and proper operating pressure. The cause of most drip irrigation system failures is either high pressure or clogged drip emitters, therefore, a screen filter and a pressure regulator are the most important components in the micro irrigation system. This drip zone kit provides the user with a complete kit that includes two extra parts to allow automation of the system and connection to the drip tubing.
The 24VAC in-line valve is a heavy duty, high flow 24-volt electric valve that operates with any AC controller on the market. The valve’s reinforced diaphragm provides reliable operation under a range of incoming pressures and operates even with contaminated water.

The screen filter is a simple and economical method for protecting a drip irrigation system. Periodically, the filter screen needs to be cleaned by opening the filter cover, removing the screen and rinsing the screen under water.
The preset pressure regulator is used to reduce and regulate the incoming pressure of the household’s water entering a drip irrigation or micro sprinkler system to the appropriate operating pressure range of 25 PSI, which is within the range of recommended operating pressures for a micro irrigation system.

Installation into pipe thread

  1. If the installation is into a PVC pipe, first shut off the main water supply.
  2. We recommend installing a 3/4” ball valve or gate valve before the drip zone kit. This ball valve can be very useful as an emergency backup to turn the system off. This type of arrangement is used by professional installers.
  3. Turn the water supply on to flush the line and then shut the water supply off using the new ball valve or gate valve.
  4. Install the 24VAC Drip Zone Assembly Kit, wrapping TEFLON tape on all the male thread fittings used.
  5. Turn the water supply on again to pressurize the system. The unit will open momentarily and then will shut off.
  6. Connect the 24VAC 3/4” in-line valve, then the 3/4” screen filter with 155-mesh (model D55), followed by the 25 PSI pressure regulator (model D46P), and ending with the 3/4” swivel adapter (model 5001) to connect the drip zone assembly into a drip tubing. If the system is continued with PVC pipe, then connect a 3/4” PVC female thread x slip adapter to the pressure regulator and glue it to the PVC pipe.
  7. Test the valve using the manual bleed. Check that the system is working and that there are no leaks.
