Iron and Bronze Valves are available in a wide range of sizes and flow rates to cover most applications. The unique design allows a straight flow pattern with low friction loss. A direct sealing diaphragm, the valves only moving part, operates by pipeline or external pressure. Sizes range from 1" to 24" with a variety of control functions and connection options.
- Unique design allows a straight flow pattern with lowest friction loss in the industry.
- Superb hydraulic performance with low operating pressure.
- Direct sealing diaphragm for positive opening and closing.
- Simple inline installation with minimal parts provides low maintenance requirements.
- Iron valves have protective polyester coating for resistance to corrosive elements and UV protection.
- Bronze valves are designed to resist cavitation where extreme flow velocities exist.
- Excellent for high pressure applications
- For drip and sprinkler irrigation systems
- Center pivot control
- Permanent systems

Netafim Basic Valve Manual Operation
The basic valve can be operated manually through the use of a 3-way selector. Selector options and their functions include:
(C) CLOSED Upstream pressure or pressure from an external source is applied to the control chamber. Initiated by the spring, the diaphragm is pressed down to close the valve drip-tight.
(O) OPEN Relieving the water or air pressure to the atmosphere from the control chamber causes the valve to open.
(A) AUTOMATIC The automatic port of the 3-way selector is connected to a solenoid, hydraulic relay or pilot, which controls the valve. The common port of the 3-way selector connects the control chamber to either A, O, or C, depending on the direction the selector is pointed.
