Baxi Thermostatic Control Valve 2 Way 7687147

The Baxi 2 way thermostatic control valve, part number 7687147, is a flow-control component used to regulate temperature within the appliance's water circuit. It is a two-port thermostatic valve, meaning it modulates flow between two paths in response to temperature rather than simply opening or shutting. Baxi supplies this valve as a service spare for the commercial appliance range covered by the compatibility data below.

• Temperature at the outlet drifts away from the set point, or the appliance cycles between hot and cold.
• The valve no longer modulates and behaves as fully open or fully closed.
• Flow through the controlled circuit stops or reduces noticeably with no other cause found.
• The valve body, spindle or actuator shows scale, corrosion or mechanical damage.
• Repeated lockout or temperature-related fault codes traced back to the control valve.

• Confirm the appliance model and serial number against the compatibility list, as Baxi uses different valves across ranges.
• Check the valve currently fitted for the alternative number 1134715, which may appear on older stock or documentation.
• Inspect the mating faces and any seals or gaskets at the same time, as these are often disturbed during removal.
