Valves

Part No. Structure:

AAA valves use a simplified model code which calls out the most important characteristics with a minimum of coding. In the example, model ESY3G is a double solenoid valve, 3/8" size, spring centered spool, float center type.

The first three letters in the code (ESY) designate the type of operator on the left and right ends respectively when viewing toward the side with the "A" and "B" ports. The numeral (3) gives valve size in 8ths of an inch. This completes the model code for many valves. If, however, additional features are desired, one or more suffix letters can be added.

TYPICAL OPTIONS
C = Cam
E = Friction Position
F = Foot Pedal
G* = Direct Pilot
H = Manual Lever
K = Palm Button
O = Spring Offset		 P = Piston
R = Pilot

*Special prefix for 1-1/2" and 2" air valves to designate valve body only, without a piggy back operator.

All Solenoid Valves:We have changed our standard solenoid assembly to a new PLC friendly solenoid. To differentiate this style from our previous valves, please use a prefix of "E" to all new solenoid valves. For additional information please see our printed catalog or a PDF version available in our catalogs section.

Stack Series Valves:B-Series valves are similar in construction to the 1/4" & 3/8" side ported valves. B-Series are only available in 1/4" & 3/8" NPTF port sizes. To order a 1/4" manual lever valve, spring return in a stack valve you would add the prefix "B" to the part number (i.e. BH02). For additional help in ordering stack valves contact your local distributor or the factory.

Namur Series Valves:N-Series valves are similar in construction to the 1/4" & 3/8" side ported valves. N-Series are only available in 1/4" NPTF port sizes. To order a 1/4" solenoid valve, spring return in a Namur valve you would add the prefix "N" to the part number (i.e. NS02). For additional help in ordering Namur valves contact your local distributor or the factory.
