N Series
This small flare brass valve series is ideally suited where space is at a
premium. Its stainless steel power element and compact body has always
made it the first choice for installation in commercial refrigeration systems.
External equalized models are provided with a 30" capillary and 1/4" SAE
flare nut, eliminating the need to run a separate equalizer line. Medium,
low & MOP (X) charges are available as noted below.
