Gas Proving Accessories & Spares

The ancillaries that complete a Merlin gas interlock installation. GoldSeal normally closed gas solenoid valves provide the isolation the panel controls, available screwed or flanged in sizes from 50mm to 100mm, all 230V. Merlin CS1 and CS2 current switches prove that extract fans are running, with the Air PD air pressure differential switch as the alternative fan-proving method, and the mushroom-type emergency stop gives remote gas knock-off at the panel. All are designed for use with our Gas Proving Systems range and are covered by S&S Northern's three year warranty.
