Description

Air valve for pre 1993 Hot Spring models, 1/2 bezel.

The air control valve, located on the bartop, allows the spa user to control/adjust the amount of air that is supplied to all the hydrotherapy jets in the spa. The amount of air is controlled/adjusted by turning of the air lever. The more air, the stronger the jet pressure feels. The air is drawn from the equipment compartment. Air check valves, mounted under the bartop in the equipment compartment, provide the air intake for the air control valves.

The force of the water pressure rushing through the individual jets in a venturi effect inducts the air through the air valve.

The air control valves consist of a lever, bezel, piston driver, o-rings, screw, and valve body. The valve body connects jet's air intake with the air check valve (located in the equipment compartment). The piston driver opens and closes to allow air to flow to the jets. The lever is used to turn the piston driver.
