Application and Selection
Match the original inlet thread, pilot outlet connection, mounting and both pressure settings. This valve controls another device through a pilot signal; it is not a direct replacement for a discharge-unloader/check-valve combination or a certified safety relief valve. Keep the compressor’s separate pressure-protection devices in place.
