The Prefect Irus PRE2000ASOV automatic shut off water valve, when used in conjunction with the PRE2000WSO control, removes the risk of severe water damage by cutting off the water supply to the hot water cylinder.

This simple and robust actuator offers a compact actuated valve solution with on off and failsafe functionality.

Used in conjunction with the Prefect PRE2000WSO water shut off system, the valve allows quick and reliable cold-water shut off to protect the buildings infrastructure.

An operation indicator window, mounted on the top of the unit housing, allows quick visual status at a glance.

A manual override provides building personnel the ability to reinstate flow manually in case of fault or power failure.

The PRE2000ASOV is fitted with a two meter cable and multi-way connector for quick connection to the PRE2000WSO.

Other valve sizes are available please contact the office with you specific requirements.
