Check compatibility before ordering

Match the full PEL 791911 reference, mounting arrangement, fitting threads, thermocouple connection and control shaft dimensions to the replacement specified by your appliance manufacturer. A similar appearance or the 22S series name alone does not confirm compatibility.

This is the horizontal 22S/O version. Do not assume it is interchangeable with a vertical 22S/V valve or a version with an M8 thermocouple connection.

Have an appropriately qualified gas engineer confirm suitability for the appliance, including gas type, operating pressure and installation requirements. Installation should follow the appliance and valve manufacturer's instructions.

Controls and connecting nuts

The valve is available with or without connecting nuts. Lever and knob controls are also available separately. Contact Under Control Instruments to confirm which supply option and control are suitable for your application.
