Brass Drop Arm

Brass Drop Arm

The Masefield Beta brass drop arm is designed to ensure the correct air gap between the water level and the valve outlet, reducing the risk of back siphonage into the mains water supply. Manufactured from high quality brass, this durable component is suitable for all float operated piston type valves, including piston operated ball valves.

Available in a choice of lengths and sizes, the drop arm can be matched to individual installations. Care should be taken to select the correct length to ensure the float does not swing beneath the valve body.
