List of products
Gate valves with FF threaded connection (1", 5/4", 6/4", 2") serve as shut-off fittings on larger-diameter water pipework, where a direct passage of the medium with minimal pressure loss is required in the open position.
Replacement handles for ball valves are supplied in two colour versions – blue for cold water pipework, red for hot water or heating pipework – allowing the individual circuits to be visually distinguished at a glance. They are available in size ranges 1/2"-3/4", 1"-5/4" and 6/4"-2" according to the size of the valve body.
Frequently Asked Questions
- Why do the handles come in different colours? The colour coding (blue/red) helps to identify the cold water and hot water or heating circuit at a glance.
- Does a replacement handle fit any ball valve? No, the handle is selected according to the size range matching the size of the original valve body.
- What is the difference between a gate valve and a ball valve? A gate valve shuts off flow with a sliding plate perpendicular to the pipe axis, while a ball valve uses a rotating ball with a bore – both are used for shutting off flow but differ in construction and use for larger dimensions.
