Iron Valves

Iron 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.

Why Iron Valves

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.

Iron Valves Operation

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.

Product Advantages

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.

Applications

Excellent for high pressure applications
For drip and sprinkler irrigation systems
Center pivot control
Permanent systems
