Replacement PEL 22S/O Flame Failure Gas Control Valve – Horizontal Mount

The PEL 22S/O horizontal flame failure gas control valve is a replacement component for compatible commercial gas appliances. Designed for horizontal installation, it provides flame failure shut-off with a manual reset and an M9 thermocouple connection.

Replacing an existing PEL valve? Start by matching the model reference and mounting orientation, then have your engineer confirm the connections and operating requirements before ordering.

Flame failure protection for compatible equipment

This flame failure device (FFD), also known as a flame supervision device (FSD), works with a compatible thermocouple to shut off the gas supply following loss of flame. A manual reset is required after shut-off.

Check compatibility before ordering

This is not a universal-fit gas valve. Confirm the appliance manufacturer's specified replacement, the existing valve reference, gas type, operating pressure, inlet and outlet fittings, shaft dimensions and thermocouple connection before ordering.

This listing is for the horizontal model, not the vertical PEL 22S/V. Do not substitute one mounting version for the other without confirmation from the appliance manufacturer.

Installation and compatibility checks should be carried out by an appropriately qualified gas engineer in accordance with the appliance and valve manufacturer's instructions.

Frequently asked questions

Is this the horizontal or vertical valve?

This is the PEL 22S/O horizontal version. Match the mounting arrangement and model reference to the valve specified for your appliance.

Can it be used with Natural Gas and LPG?

The valve is listed for Natural Gas and LPG applications. Your engineer should confirm suitability for your appliance's gas type and operating conditions.

Will it fit any commercial gas appliance?

No. Matching the PEL model alone is not enough: the mounting orientation, fittings and operating specifications must also be suitable.

Need help identifying the right replacement?

Contact Under Control Instruments with your appliance make, model and existing valve reference before ordering. Clear photographs of the valve markings and connections can also help with identification.
