Brake Valve Plus Retract Valve
JMP's new Brake Valves plus 1-Circuit Retract Valve. The Proportional Brake Valve will activate most wheel brake designs in use today. To work best your Brake servo should have at least 100 in.oz. of torque. We use a JR 8711HV servo for this. The Brake Valve requires about .5 inches of stroke to operate from zero to full system pressure. Lesser servos will work but will buzz more when applying maximum braking. As you increase the system pressure, it requires progressively more servo torque to deliver this pressure to the wheel brakes.
