Description
The VSB.
T and VMB.
T valve family is designed for precise fluid control and mixing applications in industrial and residential air-conditioning, thermoventilation, and heating plants, as well as in machinery for thermal processes. Featuring a robust cast iron globe valve design with female threaded connections, these valves ensure stable linear regulation, reliable shut-off, and long-term performance in demanding HVAC and process environments.
The two-way VSB.
T versions are optimized for accurate flow modulation, while the three-way VMB.
T valves are intended exclusively for mixing applications. Their compact construction, reliable stem sealing, and direct compatibility with specific electric actuators make the VSB.
T & VMB.
T family a versatile and dependable solution for zone control, distribution loops, and machine-level thermal applications.
