Potterton CVI Honeywell Gas Valve 402550

This gas valve and associated O-rings and gasket provide reliable control of gas flow within compatible boilers, supporting correct operation and long-term durability. The components are designed to restore and maintain performance in heating and hot water systems, with genuine materials offered to suit Baxi and Potterton Suprima installations. The product line includes a VK4105E1007 valve and related sealing components, recognised for manufacturer-approved protection of the system.

The valve is operated by the boiler’s printed circuit board, acting as a controlled tap that opens and closes to regulate gas flow. It is designed to fit a number of Potterton Suprima boilers and is part of a genuine brand spare parts range, backed by a manufacturer guarantee.

In addition to the Baxi reference, this item is supplied as a Potterton CVI gas valve, covering the same role in controlling gas volume inside the appliance and contributing to reliable boiler operation.
