SAFETY CRITICAL PART — always ensure the correct replacement is fitted and tested by a qualified engineer before returning the fryer to service.
Replacement steam pressure safety relief valve for part number 59742, 1/2in, 15 PSI. It automatically releases excess pressure from the frying vat if pressure exceeds the safe operating limit, protecting both the equipment and kitchen staff. If your fryer is venting steam unexpectedly, leaking from the relief valve, or failing to hold pressure at the correct set point, the valve should be inspected and replaced. Purely mechanical with no electrical components, so it suits all markets — there is no country or voltage variant. Supplied from UK stock by LaunchCatering.

Always verify the part number against your equipment data plate before ordering. Installation must be carried out by a suitably qualified engineer.
How do I know my relief valve has failed?
Common signs are steam venting unexpectedly during the cook cycle, a persistent leak from the valve body, or the fryer failing to reach or hold its correct working pressure. A faulty relief valve is a safety hazard — do not operate the fryer until it has been replaced.
Is there a UK or 50Hz version?
No. Unlike the solenoid valve, this is a purely mechanical part with no electrical components, so there is a single version suitable for all markets.
Will it fit my fryer?
Check the part number on your existing valve or your equipment data plate against 59742, or send us your model and serial number and we will confirm before you order.
