QuickStop Valve from Mac3. Rapid action ball valve alternative

There isn’t much to say about one of these units. Unlike a brass ballcock, the QuickStop is either open or closed. With a QuickStop there isn’t an ever-decreasing orifice (that will close – eventually). The diaphragm design of the QuickStop uses the incoming water to lock the valve shut (incompressibility of fluids and all that).

Available in 0.5, 0.75, 1, 1.25 and 1.5” models, with both Standard and Adjustable float arms, there is a valve for every installation.

QuickStop Standard

The float arm on the Standard model has a preset deflection angle of 30^o with the float locked to the float arm itself. This allows for the water level to drop before the valve opens. The QuickStop Standard is ideal for those who only require a small quantity of water from a holding tank and prefer not to have the valve open every time water is drawn. It is also beneficial for those using a header tank or pump-fed holding tank as it reduces the number of pump restarts, thereby improving the pump’s longevity.

QuickStop Adjustable

The Adjustable model (as the name suggests) has full adjustment for both the deflection angle and float ball position. The angle can be modified to range from a fixed arm (with no deflection) to 150^o without any restrictions. During installation, the adjustment is made and securely locked in place. It can be easily readjusted if necessary.

In the Adjustable model, the float arm can be extended (by moving the float ball itself) up to 600mm from the body of the QuickStop.

The angle and float arm length variations make the QuickStop Adjustable suitable for different tank sizes and uses.

The QuickStop reminds me of my old Meccano set as a kid. So much fine-tuning available!

QuickStop Valve uses

The QuickStop can be deployed in any frost-free environment – from header tanks and analogue mains water top-up to agricultural uses like drinkers of gravity-fed irrigation systems (where power is unavailable).

The QuickStop is a quick and simple installation for a new project or retrofitted to an existing installation as a replacement or upgrade.
