Product Description
The WABCO 4721950830 is an ABS solenoid modulator valve designed to control air pressure at the wheel-end during anti-lock braking operation on heavy-duty commercial vehicles.
During an ABS event, the valve responds to commands from the ABS electronic control unit to increase, hold, or decrease brake-chamber pressure, helping prevent wheel lockup while maintaining braking control.
WABCO specifies the 4721950830 as a 12-volt valve with a bayonet electrical connector. It features a flange-style supply connection and dual 1/2"-14 Dry Seal NPTF delivery ports. Maximum operating pressure is approximately 159.5 PSI, with an operating temperature range of -40°F to 176°F.
