The DVS branded flush valves are an ideal choice for all high usage washrooms, providing reliable water saving benefits. The no touch wave operation reduces the risk of cross-contamination and the electronically operated drop valve is extremely accurate reducing the amount of excess water usage. The timer can be adjusted to any setting between 1 and 6 seconds, to deliver the optimum flush for your environment. It has been designed to be compatible with most WC cisterns on the market so it is ideal for retrofit to existing installations or new installs with the DVS cistern (sold separately).
