Metering Servomotor Assembly

The Acorn 2563-020-001 is a metering servomotor assembly supplied without a seat. It functions as a drain component for use with lavatories, showers, and combination lavatory and toilet valves. The unit includes the metering servomotor less diaphragm, orifice plate, orifice plate spring and nylon seat.

Suited For Metering Valve Repairs

This assembly suits maintenance teams repairing or servicing metering valves in commercial plumbing systems. It is not for installers who require a complete valve kit with diaphragm, orifice plate, spring and nylon seat included. Buyers needing those additional components should source a full assembly.

Direct Replacement Installation

Installation involves fitting the servomotor into the existing valve body as a direct replacement part. Because the diaphragm, orifice plate, spring and nylon seat are not supplied, installers must reuse serviceable originals or procure them separately. Missing any of these items will prevent the valve from metering correctly.

Questions about this item

Which existing Acorn valve bodies accept the 2563-020-001 metering servomotor assembly?

The assembly is designed for use with Acorn lavatory, shower and combination lavatory-and-toilet valve bodies that accept a metering servomotor without a seat trap.

Can the 2563-020-001 servomotor replace the internals of an older Acorn metering cartridge that still has its seat trap in place?

No — this unit ships without the diaphragm, orifice plate, orifice-plate spring and nylon seat, so the original seat trap and related parts must be removed before installation.

After fitting the 2563-020-001, how can I confirm the metering cycle is operating correctly?

Activate the fixture; the valve should deliver a measured flow for the preset cycle duration then shut off cleanly without drips or continuous run-on.
