Irrigation Network Butterfly valve is a quarter-turn Valve with rotary motion which is used to stop, regulate, and start the water flow. Our Irrigation Network Butterfly valves can be quickly opened. You can do a 90° rotation of the handle to completely close or open the valve. Usually, they are used in irrigation systems where a positive shut-off is not needed.
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe; passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so a pressure drop is always induced in the flow, regardless of valve position.
Dutco Tennant LLC provides Large Irrigation Network Butterfly valves made by Wouter Witzel. These valves usually have gearbox type actuator, where the handwheel is linked to the stem via a gearbox. This reduces the force and at the same time reduces the operation’s speed. You can install this type of valve in the open position.
Our Valves are premium quality Butterfly valves which are a logical and consistent improvement of the Butterfly valves which have been tried and tested for many years and they stand for the highest quality in the nominal sizes. Perfect solutions as they are, you can expect outstanding product properties in terms of operating safety, strength and price.
These valves come with an inventive shaft-hub connection which has a shut disc eye, and it does not need any extra fixing elements, and hence there is no need for separation joints. These valves offer more torque reserves as they have a notch-free polygonal profile with the same shaft diameter.
