£97.00 (£80.83 ex. VAT)

Honeywell has been designing and producing products at the highest quality for over a hundred years and have been able to build up a substantial amount of reliability in this time. This vast amount of experience means Honeywell are recognised as one of the market leaders, and their high standards keep them at the forefront of the customers minds when purchasing heating products in the future.

You can be assured this product has been produced to provide maximum reliability and durability & perfect for use in domestic and light commercial central heating systems.

The Honeywell V4073A Mid Position 3 Port Valve has been designed to control the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. It is typically suited for small to medium sized installations.

The  valve features a manual lever, which should normally be in the ‘AUTO’ position. This can, however, be changed to ‘MAN OPEN’ position for system draining and filling purposes.

The V4073A should be used in conjunction with a room thermostat and cylinder thermostat to provide full temperature control of a conventional, fully pumped central heating installation. When used in this way, the control system is known as Sundial Y Plan and the components can be connected together using the Honeywell Sundial Plan Wiring Centre which has dedicated terminations and there is no need for a wiring diagram.
