• Manual adjuster included for commissioning and manual operation
• Compatible with Siemens SSB and SSC series electromotoric actuators
• G3/4" actuator connection for easy integration with building automation systems

Applications:

• Terminal unit control in ventilation and air-conditioning systems including fan coil units, induction units, and small heating/cooling coils
• Zone control in closed-circuit heating systems for individual rooms, apartments, or building floors
• Water-side control in 2-pipe and 4-pipe HVAC systems
• Chilled ceiling and radiant heating/cooling applications

This valve is designed exclusively for mixing or 2-port applications and should not be used as a diverting valve. Suitable for use with water (per VDI 2035 standard) and water-glycol mixtures. The valve body and actuator are supplied separately for flexible installation and can be easily assembled on-site. A strainer should be installed upstream to ensure optimal valve performance and longevity.
