Netafim Series 80 3-Way Globe Valve 2 in, Electric Pressure Reducing (61PRELTH2GH3)

Netafim Pressure Reducing Valve With Solenoid on a 2 in Globe

On a straight header, one valve body can both schedule a zone and keep its emitters at the right pressure. This Series 80 build does exactly that on the 2 in globe body, model 61PRELTH2GH3. The solenoid answers the controller, opening the zone at the start of a cycle and closing it at the end. Alongside it, a reducing pilot senses outlet pressure and trims the diaphragm to hold a set point while the zone runs. Both ride on the bonnet, and nothing is plumbed to the sides of the body. Rated flow is 0.25 to 176 GPM, with 7 to 150 psi on the inlet and water up to 140°F. Fully open, the globe body loses about 0.7 psi at 40 GPM and 12.0 psi at 170 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 6-5/8 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.

Setting Up an Electric Pressure Regulating Valve

Replacing a zone valve, a separate regulator and the fittings between them with one body frees space on a crowded header. That suits drip and micro zones fed from a main that runs well above what the emitters want. Check that the solenoid coil matches the controller output before connecting any wires. A mismatched coil will either overheat or never pull in. Plumb the valve inline with the flow arrow downstream and a gauge on the outlet side. Run the zone and turn the pilot until the gauge shows the target, then let the controller take over the schedule. This electric pressure regulating valve mounts vertically or horizontally to fit the header. The flow control stem allows manual control from full closure up to maximum capacity. Quick reaction and a drip-tight seal keep cycle timing accurate on short pulses. Revisit the pilot setting whenever pumps, filters or zone layouts change.

Key Features

• Solenoid plus reducing pilot: Switches the zone and regulates its outlet pressure in one 2 in body.
• Straight globe body: Inline inlet and outlet fit a straight header run.
• 0.25-176 GPM range: Handles a single block or a full greenhouse range.
• Bonnet-mounted controls: Solenoid and pilot sit on top, with no tubing on the body.
• Three pilot spring ranges: Colour-coded springs cover set points from 7 to 90 psi.
• Flow control stem: Manual control from full closure up to maximum capacity.
• Any-way mounting: Installs vertically or horizontally along the header.
