AAA Products International, Inc. Datasheets for Industrial Valves
Valves are mechanical devices that control the flow and pressure of liquids, gases, and slurries within a system. They are also known as regulators and are used in a wide variety of applications. Valves vary greatly in size, design, function, and operation.

| 2-position, spring returned spool. Spool returns to position "C" when the pedal is released. | |
| 2-position, spring returned spool. Spool returns to position "C" when the treadle is released. | |
| 3-position, double differential pilot, spring centered, closed center spool. Spool centers when buttons are both closed or opened. See other spools on page 50. | |
| 3-position, double pilot, spring centered, closed center spool. Spool centers when pilot pressure is removed from both ports. See other spools on page 50. | |
| 3-position, friction position, positive detent in all positions. Spool stays in position when knob is released. | |
| 3-position, friction position, positive detent in all positions. Spool stays in position when lever is released. | |
| 3-position, spring centered, closed center spool. Double acting piston actuator on one end. Spool centers when pilot pressure is removed from both ports. See other spools on page 50. | |
| 3-position, spring centered. Spool returns to position "B" when handle is released. | |
| 3-position, spring centered. Spool returns to position "B" when treadle is released. | |
| 3-position, spring centered. When knob is released, spool shifts to center (position "B"). | |
| Cam roller models are operated with a cam that shifts the spool. To fully shift the valve, the cam is pushed toward the valve. Normally the cam is contacted by... | |
| Designed for operation on compressed air; not suitable for liquid service. May be used to handle inert gases, although a source of compressed air may be required for spool shifting... | |
| Differential Pilot models are operated with a button bleeder that shifts the spool. | |
| Double solenoid, 2-position, friction position. Spool shifts and remains shifted when one solenoid or the other is momentarily or continuously energized. | |
| Double solenoid, 2-position, no springs. Spool shifts and remains shifted when one solenoid or the other is momentarily or continuously energized. | |
| Double solenoid, 3-position, spring centered, closed center spool. All ports are blocked when both solenoids are de-energized. See for other spools. | |
| Double solenoid, 3-position, spring centered. Spool returns to center, position "B", when both coils are de-energized. | |
| Foot pedal/treadle models are operated with a foot pedal/treadle that shifts the spool. The standard treadle position for a 3-position valve is the center of the valve (Position "B"). To... | |
| Manual lever models are operated with a handle that shifts the spool. The standard handle position of the knob for a 3-position valve is the center of the valve (Position... | |
| Pilot models are operated with a remote pressure source that shifts the spool. To shift the valve, remote pressure source is sent to the valve. Refer to the section on... | |
| Piston models are operated with a larger piston that shifts the spool. This allows you to use lower pilot pressures to shift the valve. Because of the large piston area... | |
| Single solenoid, 2-position, pilot pressure returned spool. Pilot pressure from an external 3-way valve returns spool to its original position. | |
| Single solenoid, 2-position, pilot returned spool. Spool returns to position "C" from auxiliary control valve furnished by the user. | |
| Single solenoid, 2-position, pilot returned spool. Spool returns to position "C" from auxiliary control valve furnished by the user | |
| Single solenoid, 2-position, spring return. Spool returns to original position when solenoid is de-energized. | |
| Single solenoid, 2-position, spring return. Spool returns to position "C" when solenoid is de-energized. | |
| Standard solenoid models are assembled for "Internal Pilot" operation; that is, the valves derive shifting pressure for the spool from the valve inlet port. The required pressure to shift the... | |
| The "B-Series" stack valve consists of individual sections sandwiched between two end plates, the stack being held together with three tie bolts. Sections, listed on page 122 through page 139,... | |
| This option is only available on models KE and KO with body styles 2 and 3. This option allows the valve to be used in harsh, wash down environments. Entire... | |
