The VPD110A-135 straight radiator valve is a pressure-independent control valve (PICV) from the Siemens ACVATIX™ range, designed for two-pipe heating systems (radiators). Thanks to the integrated differential pressure controller, it provides automatic dynamic balancing of the system without the need for external balancing valves on the branches. The valve maintains the set volume flow rate constant regardless of differential pressure fluctuations within the range of 0.1 to 0.6 bar.

Features:

• Automatic dynamic balancing – no need for balancing valves on the branches
• Integrated volume flow rate presetting (6 positions)
• Constant flow rate at a differential pressure of 0.1–0.6 bar
• Normally open valve (NO) – the stem protrudes when no actuator is fitted
• No disruptive noise
• Manual setting for temporary system operation during construction
• Maintenance-free operation
• Suitable for new builds as well as refurbishment of systems with hydraulic problems
