SERIES 80
Globe & Angle Irrigation Valves
Series 80, the most modern type of valve, was designed especially for greenhouse
irrigation systems- as well as turf and field crops irrigation.
The Mod.80 valves are equipped with the unique Labyrinth device that eliminates
clogging while low- quality water is used.
A built-in manual- activation unit allows override of the electric control at any control
mode (opening without electric signal, and closure while the valve is operated by the
electric controller).
An option of Angle-pattern valves is available.
Features and Benefits
• Simple, reliable and economical
• Angle or straight, globe- pattern valve, activated by a fully-supported diaphragm
• Durable, corrosion free materials
• Unique clog-free labyrinth inlet of the activation water on electric 2-way valves
• 3 Position Manual override on electric 2-way valves
• Operation at wide range of flow rates, from near zero to the maximal flow
• Electric 2-way or hydraulic / electric 3-way actuation
• All of the control system’s devices are assembled on the valve’s bonnet.
No tubes are connected to the body
• Removable flow control stem handle (optional)
• Integral stainless-steel EasyClean® filter

SERIES GAL
Gal Plastic Valves
Description
Series 75, “GAL” plastic valves are designed for the
control of irrigation systems of field crops, vineyards and
orchards.
The exceptional hydraulic characteristics of the mod.75
enable very high flow rates, at low head losses.
Wide range of control functions, allows the design of the
irrigation networks to optimal operation.
The uPVC valves, models 95 (threaded) and 96 (solvent
welded straight to the pipe) are made for high-flow
irrigation plots and flood tables.
The direct- attachment to the PVC pipelines, the optional
underground installation, save cost of valve configurations
and reduce head losses.
Unique diaphragm design generates surge- free closure
even at high velocities.

Locate the flow rate on the horizontal axis and draw a line upwards.
Locate the line pressure on the vertical axis and draw a line to the right.
The intersection point of the two lines marks the appropriate valve size.
Example: line pressure 28m (40 psi), flow rate 23 m3/h (100 gpm), appropriate valve = model 75-2”.
Principle of Operation
1) 3-Way Control
This control device admits pressure into the
control chamber, closing the valve, or relieves
pressure to the atmosphere, fully opens the valve.
2) 2-WAY ELECTRIC CONTROL

A solenoid operator plugs the control chamber
outlet. A permanent connection from the upstream
to the control chamber ensures line pressure in
the chamber and thus valve closure. Energizing
the solenoid operator causes the control chamber
to drain to downstream, opening the valve.

Typical Applications
plastic Control valves
Pressure Reducing Valve Model 80
Made to maintain a constant, preset pressure in
greenhouses, turf and open field irrigation
plots- regardless of pump pressure or demand
variations.
Pressure Sustaining / Relief Valve Model 75
The Sustaining valve maintains a constant, preset pressure
in the inlet side, to protect pumps in case of excessive
demand. It can also be used to prevent pressure drop in
supply pipelines, when the flow exceeds the designed
value.
Relief valve drains water from the main
3-way Electric valve
Valve model 75, 1.5”-3” sizes, three-way Electric control.
Made for high- flow greenhouse irrigation, especially
for control of Flood Tables, and of Field crops irrigation
networks that are activated by sophisticated controllers.

* Standard Diaphragm: Nylon Reinforced Natural Rubber. Optional Materials: Nitrile, EPDM, Neoprene Available Upon Request.
** HP = High Pressure
Pressure Rating
Pressure rating of series 100 valves is body strength, connection standard and diaphragm type.
Pressure rating of valve body of standard models: 16 Bar / 230 psi.
Pressure rating of valve body of high pressure models: 25 Bar / 360 psi.
Connection standard is marked on the identification plate, assembled on the valve body.
Diaphragms operation pressure range is presented at the above table.

PR Pressure Reducing Valve
Description
The valve maintains a preset downstream pressure,
regardless of upstream pressure or flow rate
fluctuation.
The main valve is controlled by either a 3-way
pilot valve (allowing full opening when upstream
pressure drops below the pressure set-point), or by
a 2-way pilot valve (creating a minimal differential in
open position).
