What it is

The Honeywell V1810Y0025 is a Kombi 4 shut-off and throttle valve with a 1" connection. It combines isolation and flow throttling in a single valve body, so a circuit can be shut off or balanced from one point on the pipework. It is intended for heating and plumbing installations where both duties are needed at the same location.

Before you order

  • Confirm the pipework takes a 1" connection before ordering.
  • Check the part number on the existing valve or the system documentation matches V1810Y0025.
  • Confirm that both shut-off and throttling duties are required at the same point in the circuit.
