Valve Type Comparisons

We like to offer our online readers some news, tips and advice concerning sprinkler irrigation here in the Central Florida area. Today we would like to explain the pros and cons of different valve types for sprinkler irrigation systems.

A gate valve is a general service valve used primarily for on/off, non-throttling service. The valve is closed by a flat face, vertical disc, or gate that slides down through the valve to block the flow.

A ball valve uses a rotating ball with a hole through it that allows straight-through flow in the open position and shuts off flow when the ball is rotated 90 degrees to block the flow passage. It is used for on-off and throttling services.

A butterfly valve controls flow by using a circular disc or vane with its pivot axis at right angles to the direction of flow in the pipe. The butterfly valve is used both for on-off and throttling services.

Latching solenoids do not have a constant source of power to them. These valves use an electric pulse, meaning it has the primary pulse to cut it on but a secondary pulse acting as a switch to cut it off. Sometimes these valves have a tendency to hang up so the zone would be stuck on or inoperational.

In addition to these standard valve products, many valve manufacturers produce custom-designed valves and actuators for specific applications. Valves are available in a broad spectrum of sizes and materials. Each design has its own advantages, and selection of the proper valve for particular application is critical.
