The V4073A 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 V4073A Mid-position Diverter Valve 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 Sundial Plan Wiring Centre which has dedicated terminations and there is no need for a wiring diagram
• 22mm compression, 6.0 KV
• Maximum close-off differential pressure 0.69 bar
