Netafim Series 80 3-Way Globe Valve 1-1/2 in, Hydraulic Pressure Reducing

Netafim 3-Way Globe Valve for Inline Pressure Reduction

Inline runs do not always have room for an angle valve, and that is where this straight-through body comes in. This is the 1-1/2 in Series 80 globe body in 3-way form, fitted with a hydraulic pressure reducing pilot, item 71610-014306. The pilot senses outlet pressure and adjusts the main diaphragm so the downstream side holds its set point while the supply moves around. Pilot and controls sit on the bonnet, so nothing is plumbed into the side of the body. Rated flow is 0.25 to 110 GPM with 7 to 150 psi on the inlet and water up to 140°F. Fully open, the globe body loses roughly 1.3 psi at 40 GPM and 5.0 psi at 90 GPM. Glass-reinforced polyamide makes up the body, bonnet and seat, with 304 stainless hardware and a 302 stainless spring. The valve is about 6-9/16 in long, 6-1/2 in wide and 6-3/8 in tall, and weighs 2 lb. Pilot springs come colour coded by range: yellow 7-30 psi, green 14-65 psi and red 30-90 psi. There is no solenoid on this model.

Running a Netafim Pressure Reducing Valve Inline

Drop it into the mainline ahead of a drip or micro-sprinkler block whose emitters want less pressure than the pump or city main delivers. The straight body suits manifold rows and wall-mounted headers where every valve sits in line. After plumbing, bring water up slowly so the valve fills without a pressure spike. Then set the pilot against a gauge just downstream until the block reads its target. Give each adjustment a moment to settle before the next one. This Netafim pressure reducing valve can mount vertically or horizontally, which helps when the header runs along a wall. Being hydraulic, it regulates whenever water is present and cannot be switched off by a controller. Zones that also need scheduling pair it with an electric valve upstream or downstream. Its main limit is that it only lowers pressure; it cannot raise a weak supply. Recheck the set point at the start of each season and whenever the supply side changes.

Key Features

• Hydraulic reducing pilot: Holds a steady outlet pressure regardless of swings in the supply.
• Straight globe body: Fits inline on headers and manifolds without changing the pipe direction.
• Bonnet-mounted controls: Pilot and controls sit on top, keeping the body sides clear for tight manifolds.
• 0.25-110 GPM range: Regulates anything from one drip block to a large multi-lateral zone.
• Three pilot spring ranges: Colour-coded springs cover set points from 7 to 90 psi.
• Vertical or horizontal mounting: Works upright or on its side along a wall-mounted header.
