Netafim - Iron and Bronze Valves

• Unique design allows a straight flow pattern with the 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.

3-Way Control Valves

The 3-Way control valve only ports water (or air) into the control chamber to close the valve or releases it from the control chamber to open the valve. This non-continuous porting technique allows for full opening of the main valve when operating conditions require the valve to be fully open.

Manual Valve Operation With A 3-Way Selector

• CLOSED (C): 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.
• OPEN (O): Relieving the water or air pressure to the atmosphere from the control chamber causes the valve to open.
• AUTOMATIC (A): 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.
