Check Valves

Check valves (non-return valves) prevent the backflow of water or gas in a pipe, protecting pumps, boilers and metering equipment from damage or incorrect flow. They are used in heating, water and gas systems.

Our range includes horizontal floating check valves as well as angled ball valves with a non-return function (butterfly type) in sizes 1/2" and 1", suitable for both horizontal and angled pipework.

Frequently Asked Questions

• When is a check valve needed? Wherever backflow of the medium needs to be prevented, for example after a circulation pump or before a meter.
• Can a check valve be installed in any position? Horizontal floating valves are installed horizontally according to the directional arrow on the body, while angled versions depend on the type of installation.
• What is the difference between a check valve and a ball valve with a non-return function? A ball valve with a non-return function (butterfly type) combines shut-off and check valve functions in a single body, saving space in the pipework.
