Series 80 Pressure Reducing Electric Valve in One Body
Most zones need two things at the head: something to turn them on, and something to keep pressure in the emitters' comfort band. This Series 80 build does both, item 71610-014309. A solenoid and a reducing pilot ride on the bonnet of the 1-1/2 in globe body. The solenoid handles on and off from the controller. The reducing pilot trims the diaphragm to hold a set downstream pressure whenever the zone runs. Nothing is plumbed to the side of the body, so the assembly stays compact. Flow is rated at 0.25 to 110 GPM, with 7 to 150 psi on the inlet and water up to 140°F. Fully open, the body loses about 0.3 psi at 20 GPM and 5.0 psi at 90 GPM. Body, bonnet and seat are glass-reinforced polyamide, with 304 stainless fasteners and a 302 stainless spring. It measures about 6-9/16 x 6-1/2 x 6-3/8 in and weighs 2 lb. Pilot springs are colour coded for range: yellow 7-30 psi, green 14-65 psi and red 30-90 psi.
Where a 3-Way Irrigation Valve With a Pilot Pays Off
The obvious win is a cleaner valve box: one body replaces a zone valve plus a separate regulator and the fittings between them. That matters on greenhouse headers where every inch of manifold is spoken for. It suits drip and micro zones fed from a mainline that runs well above what the emitters want. Clog-free command water passages let it run on dirty water, and the drip-tight seal closes cleanly at the end of each cycle. Set it up by running the zone and turning the pilot until a downstream gauge reads the target. Once it holds, the controller takes over the schedule. The flow control stem allows manual control from full closure up to maximum capacity. This 3-way irrigation valve mounts vertically or horizontally to suit the header. Match the solenoid coil to the controller output before wiring, since a mismatched coil either burns out or never pulls in. Pressure only comes down through the pilot, so a supply that is already too low needs a pump, not a valve.
Key Features
- Solenoid plus reducing pilot: Switches the zone from the controller and regulates its downstream pressure in one body.
- Bonnet-mounted controls: Solenoid and pilot sit on top, with no tubing plumbed into the body sides.
- 0.25-110 GPM range: Covers a single drip block or a large multi-lateral zone on one valve.
- Three pilot spring ranges: Colour-coded springs cover set points from 7 to 90 psi.
- Flow control stem: Allows manual control from full closure up to maximum capacity.
- Vertical or horizontal mounting: Fits upright or flat along a greenhouse header.
