WABCO ABS Modulator Valve<\/span><\/h4>\n

Fast solenoid switching drives the\u00a0WABCO ABS Modulator Valve<\/strong>\u00a0through the rapid pressure changes a hard stop demands. It takes its command from the controller and adjusts brake pressure at the wheel it serves. The valve can drop and restore that pressure many times across a single stop. This unit fits off-highway machines that run their brakes on a pneumatic circuit away from public roads. Its place is at the modulation point where the anti-lock action reaches the brake. Acting on the controller’s signal, the\u00a0WABCO 4721950790<\/strong>\u00a0carries out the pressure changes each stop needs.<\/span><\/p>\n

Features & Benefits<\/span><\/h4>\n
    \n
  • Releases pressure at a locking wheel then reapplies it in a split second<\/span><\/li>\n
  • Sits close to the wheel end to shorten the path a pressure change travels<\/span><\/li>\n
  • Answers the controller within milliseconds as road grip changes under the machine<\/span><\/li>\n
  • Handles the dust and jarring of a quarry or site machine at the axle<\/span><\/li>\n
  • Holds full pressure when no correction is needed so normal braking feels unchanged.<\/span><\/li>\n<\/ul>\n
