220 Series Brass Valves Installation Instructions Introduction Built on proven technologies and components, the Toro 220 Series brass valves are tough, have excellent performance and are extremely reliable. A self-flushing, clog-resistant, stainless-steel filter for dirty water conditions assures years of trouble-free performance. In commercial installations, it is advantageous to install the valves in a valve box.

This enables the valve to be located, accessed and maintained easily. The use of clean aggregate in the the bottom of the box, and keeping valve box locations away from structures, potential hardscaping features (such as sidewalks) and large planting locations is recommended. Additionally, valve box locations generally should be in shrub beds and at right angles to structure locations. If the valves are installed below grade without a valve box, access to the top of the valve should be provided using a section of 4 ” PVC pipe and a Toro Valve Cover (Part No. 850-00) installed directly over each valve.

Follow the installation instructions provided with the connectors for optimum waterproof splice protection. · Leaving a wire expansion loop at each valve location on long-run wire lengths is recommended. Valve Operation and Adjustment Flow Control The flow control is used to reduce the flow and pressure to valve outlet. By turning the control handle clockwise, the flow will gradually be reduced zero. · For valve models without EZReg, adjust the flow control as necessary for optimum sprinkler performance. · For valve models with EZReg, the flow control should remain in the fully open position. Use only for emergency shut off. Manual Bleed Knob The manual bleed knob is used to manually operate the valve. Turning the knob counterclockwise 23 turns allows water to bleed downstream from the diaphragm chamber, relieving pressure from the top of the diaphragm which allows the valve to open. Turning the bleed knob clockwise until finger tight, shuts off the discharge enabling pressure to build within the diaphragm chamber, causing the valve to close. EZReg (pressure regulated models only) An accurate, adjustable dial coupled with a forward-flow valve design allows the 220 series valve with EZReg to regulate downstream water pressure with precision. It can regulate accurately down to 5 GPM flow (1 ” model) and only requires 10 PSI differential pressure to operate. The EZReg will operate during powered and manual valve operation. To adjust, remove the cover from the regulator dial. Turn the dial until the pointer is on the desired downstream pressure: 530 PSI (EZR-30) or 5100 PSI (EZR-100). Note: Due to the micro-adjustment feature of the EZReg, the dial requires several complete revolutions to move the pointer from the minimum to the maximum adjustment settings. Operate the valve (electrically or manually). Check the flow control to confirm that it is in the fully open position. Adjust the regulator dial if necessary for optimum sprinkler operation. To confirm the downstream pressure using a pressure gauge, remove the cap from the Schrader-type valve located directly below the EZReg. Attach a Toro pressure gauge (Model 995-51) to the Schrader-type valve for a direct reading. Adjust EZReg dial as necessary for the desired pressure. Note: The valve will remain operational if removal of the EZReg assembly is required. 1999 The Toro Company, Irrigation Division Form Number 373-0027 Rev A …
