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.

Belimo BTU Meter / Thermal Energy Meters (TEM)
Applications
Belimo thermal energy meters meet the requirements of EN1434 and have type approval according to MID 2014/32/EU. Types without approval are equipped with glycol compensation, who reliably measure the energy even if there is glycol in the water.
Energy billing made easier than ever
Belimo's certified Thermal Energy Meters meet the requirements of EN 1434 and have type approval in accordance with the European Measuring Instruments Directive 2014/32/EU (MID). They provide validated data for invoicing purposes, which can be used for direct tenant billing. Our Thermal Energy Meters are also available as variant without MID / EN 1434 approval. They can reliably measure energy, even when there is glycol in the water. They automatically and continuously measure the glycol content in the fluid, compensate for it and, in doing so, ensure reliable ultrasonic volumetric flow measurement. This results in precise determination of the thermal energy. Belimo Thermal Energy Meters™ are designed to be multi-application devices, i.e. they can be used as heat application, cold application, or combined heat/cold application. They can also be installed either in the return pipe or in the supply pipe of the system. The application and installation position are provided to the valve during setup using a smartphone and the Belimo Assistant App or using a laptop and the built in web-server.
