Automatic Load Sensing ValveTechnical DataPart number:475/714/500/0Operating PressureMediumOperating temperature rangeBraking PartControl partmax. 10 barmax. 12 barAir-40 0 C bis/to +80 0 CWABCO automatic load sensing valves replace fixed ratiovalves in trailers featuring conventional or ABS brakingsystems and air suspension. Full-trailer configurationsrequire an additional automatic load sensing valve tobe fitted between the first tee and front relay valve onthe control line (refer dwg). The valves must be installedvertically, using at least two of the four assemblingscrews provided.Brake imbalance is the primary contributor to premature brake wear andresulting running gear failures. WABCO automatic load sensing valves (LSVs)can now be used on trailers with air suspensions to reduce the risk of thishappening.Locked ratio valves maintain the same braking proportion at all times. Thesetting must be sufficient for when the vehicle is fully loaded, which meansit is effectively over-braking when the vehicle is not. In some instances truckand trailer units can have very different ratio levels, despite both beingwithin NZ brake code requirements.WABCO automatic load-sensing valves solve these problems. They adjustthe air pressure according to the load on the trailer (sensing pressure in theairbags), improving brake balance considerably. This helps to avoid brakelock-up, flat spots on tyres and shunting effects on the tow-coupling.From September 2004, all Transpecs air suspension brake kits includeWABCO LSVs in place of fixed ratio valves. Warranty conditions on axlesalso require that WABCO automatic load-sensing valves be fitted on unitsfeaturing air suspensions. Retro-fit options are also available. Please contactone of our brake specialists with the following details if you wish to discussoptions for your vehicle(s):1. Make and model of suspension2. Diameter of air spring3.
