The V4043C is a motorized two-port zone valve with 1/2" threaded connections. Suitable to control flow in domestic and light commercial central heating systems. The valve can be plumbed at any angle however the powerhead should not be below the horizontal level of the pipework. If fitted in a confined space, ventilation must be available to keep the valve within its ambient temperature range and access should be available for removing the powerhead if required
