Belimo H7125S - 3-way globe valve DN 125

Belimo H7125S – 3-way globe valve

Flanged valve for closed water systems. It can operate as a mixing valve A+B to AB or a diverting valve AB to A+B. In diverting mode, the permissible pressure values are lower than in mixing mode.

Key features and specifications
