 LIMITING & QUICK

RELEASE VALVE

The Bendix

®

 LQ-2

™

 limiting and quick release valve is a dual

function valve; the valve serves to limit brake applications
and is generally used on the front or steering axle of a vehicle.

The LQ-2

™

 valve is controlled by a TW-1

™

 control valve, (see

Figure 2) which is mounted in the vehicle cab within reach of
the driver. Placing the control valve in the “Slippery Road”
position will reduce front axle service application pressure
by 50%. With the control valve in the “Dry Road” position,
there is no reduction of service application pressure. In
addition, the LQ-2

™

 valve serves a quick release function,

releasing air directly from the front axle chambers.
