The SVM-21E smart valves are battery-powered open/close valves designed for remote flow disconnection and operate using the M-Bus protocol. They feature a manual override isolation function, integrated software for monitoring, control, and error reporting, and are encased in an IP68rated protective housing for durability.
The upgraded SVM version is specifically tailored for chilled water applications, where high levels of condensation and moisture are common. It is equipped with an IP68-rated motor and additional sealing mechanisms to ensure reliable performance even in high-condensation environments or when submerged.
These valves are available in sizes ranging from DN15 to DN40 and are fully compatible with all M-Bus master systems.
