Catalog E-1, Thermostatic & Automatic Expansion Valves / Page 5 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.
Page 6 / Catalog E-1, Thermostatic & Automatic Expansion Valves C(E) Series The C(E) series incorporates an angle style brass body with SAE flare fittings using balanced port construction, allowing operation over varying load conditions. Designed for use on small refrigeration and or air conditioning systems, the external equalized models are provided with a 1/4" SAE male connection.
Catalog E-1, Thermostatic & Automatic Expansion Valves / Page 7 SC(E) Series The SC(E) series refrigeration right angle brass body expansion valve incorporates a removable inlet strainer that may be replaced or cleaned without removing the valve from the system, and is an ideal choice for commerical refrigeration and supermarket applications.
Page 8 / Catalog E-1, Thermostatic & Automatic Expansion Valves EC(E) Series The EC(E) series features extended ODF solder connections, brass body and balanced port design. It is suited for both refrigeration and air conditioning applications.
Catalog E-1, Thermostatic & Automatic Expansion Valves / Page 9 H Series and HC Series The H series balanced port valve is designed specifically for air conditioning and heat pumps used in both air or water source systems. It offers features such as bleed ports and a variety of connection styles for the inlet, outlet and external equalizer. The HC series adds a built-in 5 ton check valve for R-22, R-407C and R-410A heat pump applications with either factory set or field adjustable superheat.

Page 12 / Catalog E-1, Thermostatic & Automatic Expansion Valves EBS Series The EBS series valve is a brass bar body valve for R-22 and R-407C. The Type EBS features a balanced port construction and extended ODF connections. The thermostatic element is replaceable. The balanced port construction makes this valve ideally suited for air conditioning applications which operate over widely varying conditions.
Catalog E-1, Thermostatic & Automatic Expansion Valves / Page 13 OE Series The OE series valve utilizes balanced port construction to provide optimum operation on medium to large tonnage air conditioning systems. Two brass body styles with copper ODF connections and a removable thermostatic power element provide the stability and control required in a variety of applications, especially where there are wide changes in load conditions.
