Multi-Valve Assembly, 1" Remote Control Valves, 6 valves. P/N 8106

The valve system shall consist of 3, 4, 5, or 6 remote control valves, of which 2 and/or 3 bodies and connecting conduit are manufactured as one piece. This assemblage is mounted on each side in a modified standard 12-inch valve box, separated and supported by a tee union ball valve.

The valve box shall be constructed of polyethylene with a bolt-down security lid, pre-drilled for valve outlets.

A wiring harness shall be pre-installed in the valve box, having a waterproof disconnect at each valve, and shall be connected to a pre-wired terminal block. The assembly shall include a snap-on cover containing silicone dielectric to waterproof the controller-to-terminal connections.

The ball valve shall have a manual open/close control. The body shall be constructed of heavy-duty, glass-filled, UV resistant nylon. The ball seals shall be constructed of Teflon with Buna-N backup rings. The connection shall be a union internal threaded coupler.

The control valves shall be normally closed, remote controlled, pilot operated, three-way, 24 VAC 50/60 cycle, solenoid-actuated with angle pattern. Valve pressure rating shall be not less than 200 psi. The valve shall have a fully encapsulated, one-piece 24 VAC 50/60 Hz electrically energized solenoid.

The valve bonnet and body/manifold shall be constructed of heavy-duty, glass-filled, UV- resistant nylon. The bonnet-to- body connectors shall consist of brass inserts and stainless steel hex-head washer-slotted machine screws. The one-piece diaphragm shall be nylon-reinforced Nitrile rubber.

The valve shall have a nylon-reinforced flow control stem for accurate manual regulation and/or shutoff of outlet flow.

The valve shall have a manual open/close control (internal bleed) for opening and closing valve without electrically energizing the solenoid, eliminating water entering the valve box.

The valve shall have a cross handle manual open/close control (external bleed) for opening and closing valve without electrically energizing the solenoid, used for flushing or when external porting is permissible.

The valve shall have a self-cleaning stainless steel metering pin.

The valve construction shall be such that, by partially loosening the bonnet screws and rotating the bonnet counter-clockwise 1/8 turn, all internal valve parts are accessible without removing the valve from the pipeline.

The valve shall be as manufactured by Olson Irrigation Systems, Santee, California.
