Belimo Zone Valves
Applications
Belimo ZoneTight™ zone valves and actuators are designed for maximum efficiency in tight spaces.
Efficient in Every Way
Designed for maximum efficiency in tight spaces, Belimo’s ZoneTight zone valve offering sets new design and performance standards for both pressure dependent and pressure independent zoning applications. Unlike short stroke globe valves, the self-cleaning ball helps minimise energy losses caused by clogging and eliminates overflow from pump pressure seat lift. In addition, high close-off capabilities ensure shut-off and allow for true equal percentage flow characteristics.
Super Compact and Versatile
Unlike short stroke globe valves, the zone tight self-cleaning ball helps minimise energy losses caused by clogging and eliminates overflow from pump pressure seat lift. Also, high close-off capabilities ensure shut-off (0% A – AB leakage) and allow for true equal percentage flow characteristics. Belimo’s ZoneTight zone valves are designed for maximum efficiency in tight spaces.
