Anti-Lock Braking System Modulator Valve
Bendix

High-performance modulator valve designed for anti-lock braking systems in heavy trucks, delivering controlled modulation of brake pressure through a 3-way valve arrangement. The unit features timed duty cycles (15/300 seconds) and a maximum solenoid-on time of 150 seconds, enabling rapid response while preventing solenoid overheating during extended braking events. Compact dimensions (61 mm width, 105 mm height, 110 mm length) and a mounting dimension of 0.34 in support straightforward installation in standard valve cavities. Electrical interface provides 12 V supply and 4.6 A draw, compatible with common vehicle harnesses, and uses 1/2-14 NPT in and delivery ports for plumbing. Maximum operating pressure is 150 psi, with an operating range from -40 to +185 Deg.F and an exhaust port with a dust shield for durability. Construction features a circular DIN connector and a three-way, SZ class core, with anti-compounding and four-port delivery. Category 41354 groups these into ABS modulator components, aligning with Bendix lineups and providing cross-references for compatible units during replacement. Technicians should verify connector type, port sizing, and solenoid operation under varying braking conditions.
