Solenoid Valve Nomenclature
The numbering system allows every user an easy method to identify, select and understand the valve being
purchased. The following table describes the numbering system
Nomenclature for Complete Valve Assemblies:
For combined Valve and Coil Assemblies:
Step 1: Select the Valve catalog number based on the
application requirements as specified in the indi-
vidual catalog section based on the connection type,
port size, connection size and rating.
Step 2: Add the optional Manual Stem, if required.
Step 3: Select the appropriate coil type and wattage
per the valve specification chart based on the sys-
tem pressures. Either 10 watt or 22 watt coil.
Step 4: Use the Voltage Code to specify the correct
voltage.
Example:
Step 1 & 2: To order a 2-way normally closed valve, 1/2
ODF connection, manual bypass option, R22, 5 ton
liquid line rating, reference R20 valve catalog page.
Select R20E84M.
Step 3 & 4: To order a junction box coil assembly, 10W,
208-240VAC rating, reference coil assembly catalog
page. Select K1U3.
To order fully assembled valve with coil, simply add the
2 part numbers together.
Example: R20E84M + K1U3 = R20E84MK1U3
For Valves Only:
Valve assemblies can be ordered as separate items.
Simply select the catalog valve number in steps 1 & 2
above.
For Coil Assemblies:
Coil Assemblies can be ordered as separate items.
Simply begin the coil assembly part number using an
“R” and follow steps 3 & 4 above.
Example: To select a junction box coil assembly,
10W, 208-240VAC rating, reference coil assembly
catalog page. Specify RK1U3.
