What it is

The Siemens VXP 45 is a three-port diverter valve with 25mm connections and a Kvs value of 6.3, supplied with a coupling. It forms part of the Siemens VXP 45 valve range and is used to divert flow between two circuits in heating and hot water systems. The Kvs figure indicates the flow rate through the valve port at a defined pressure drop, making the valve suitable for sizing against the system duty.

Before you order

  • Confirm the valve body part number VXP45.25-6.3/C against the existing valve or system documentation.
  • Check the pipework connection size on site is 25mm before ordering.
  • Verify the required Kvs value of 6.3 matches the flow and pressure drop requirements of the circuit.
  • Confirm whether the actuator is being retained or replaced separately; this item covers the valve body and coupling only.
