American Standard Solenoid Valve Assembly - AMS-A950503

It's the solenoid valve assembly for American Standard toilet flushing applications. The solenoid is the electrically operated valve inside a sensor-activated flush valve: when the sensor triggers, the solenoid opens and lets the flush cycle run. It's a genuine American Standard repair part, ordered under part number A950503-0070A.

The A950503 solenoid assembly is specified for toilet (water closet) applications. If you're repairing a sensor urinal flush valve, match the solenoid to that specific urinal valve model rather than assuming this one carries over, since flush volume and valve internals differ between closet and urinal valves.

That's the usual symptom of a failed solenoid. The sensor and control board are firing (that's the click) but the valve isn't opening water flow, which points at the solenoid assembly rather than the sensor eye or the battery pack. The A950503-0070A is the genuine American Standard solenoid assembly for toilet flush valves. If there's no click at all, work back to power and the sensor first.

One part number covers it: A950503-0070A. There is no finish choice because the solenoid sits inside the flush valve housing where nothing is visible, so it's supplied with no finish applied. If you need a matching cover plate or sensor escutcheon in a finish, that's a separate part.

Just the solenoid valve assembly, a repair component that goes into an existing American Standard flush valve. You're not getting a complete flushometer, supply, spud or sensor package with it. If the valve body itself is damaged, you need a complete valve, not this part.

It's the component that typically fails first in an electronic flush valve, and it's a genuine American Standard part rather than an aftermarket substitute, so a maintenance crew can swap it out in place instead of pulling the whole flushometer. Stock it against the American Standard sensor closet valves you actually have on the wall, and order by A950503-0070A.
