John Guest Drinks Grey Acetal Shut Off Valve

Designed to isolate supply to fixtures, appliances or dispense equipment within drinks dispense and water treatment systems. It incorporates a full bore 1/4 turn valve mechanism, allowing rapid and reliable shut-off without restricting internal flow when fully open. Engineered for brewing, soft drinks and potable water systems, the valve is also suitable for air and inert gases such as N2 and CO2, in accordance with the British Beer & Pub Association Code of Practice. This makes it ideal for isolating beer lines, gas feeds to regulators, secondary cooling circuits and individual bar dispense points.

The full bore design is critical in drinks dispense systems, as it maintains maximum internal diameter when open. This helps preserve flow characteristics and pressure stability, supporting consistent pour quality and minimising restriction in gas-assisted lines. Each end of the valve features John Guest push-fit technology, enabling tool-free installation and immediate leak-tight performance. The collet assembly with stainless steel teeth grips tubing securely without deformation, while nitrile O-rings ensure reliable sealing under pressure.

The short handle configuration provides compact isolation control in tight cellar or under-bar spaces. The optional mounting bracket version allows the valve to be securely fixed to panels or equipment frames, offering improved stability and easier access in permanent installations. Corrosion resistant and fully demountable, the valve supports efficient maintenance and rapid system modifications.
