PV Compact, Spectrum-series

Differential Pressure Control Valve

Save pump energy and ensure trouble free commissioning of the system with the PV Compact, Spectrum-series.

Support energy-efficient pump operation and simplify system commissioning with the PV Compact, Spectrum-series.

By design, PV Compact, Spectrum-series has a high Kv value, resulting in low pressure loss compared with conventional differential pressure control valve designs. This upgraded version of our differential pressure control valve is equipped with a scale on the cap that makes presetting much easier.

Due to fluctuating differential pressures, heating and cooling systems often create noise because the thermostatic control valves are unable to close completely.

Despite the more regular use of variable speed pumps, in larger systems the differential pressure will increase when the system is in a partial load condition. This causes an increase in system noise and the control valves to regulate inefficiently.

The PV Compact, Spectrum-series valve is designed to maintain a constant differential pressure across the load or circuit, supporting accurate control valve regulation.

Due to the compact design of the valve it is easily installed in both domestic and commercial heating and cooling systems.

Benefits

• High Kv value supporting low pressure loss and efficient system operation.
• Positive close off to prevent rising differential pressure when control valves in the controlled circuit are fully closed
• Helps reduce noise associated with high differential pressure.
• Differential pressure can be set and adjusted on site
• Tamper-proof presetting device on top of the valve, meaning there is no need for the valve sealing after presetting
• Differential pressure can be set and adjusted on site
• Simple presetting using the scale on the cap
