Sloan Royal Flushometers

ProDryers supplies the full Sloan Royal family for water closets and urinals in commercial and institutional facilities. Royal is a diaphragm flushometer line known for durable construction, accurate low-consumption metering, and an ADA compliant non-hold-open handle. Closet models are commonly specified at 1.6 gpf or 1.28 gpf. Urinal models are available at 1.0 gpf, 0.5 gpf, and 0.125 gpf. Royal comes in manual, sensor, and concealed configurations to match new construction and retrofit projects.

Why facilities specify Royal

  • Diaphragm technology engineered for consistent, low-consumption performance
  • ADA compliant non-hold-open handle that prevents over-flushing
  • Non-adjustable metering design that supports water conservation targets
  • Chloramine-resistant diaphragm components for long service life
  • Rugged brass body with Bak-Chek control stop and free-spinning stop cap on standard packages
  • Adjustable tailpiece and vacuum breaker connection for install flexibility
  • Standard polished chrome with optional special finishes

Core Royal configurations

Water closet, exposed manual

Royal 110 and 111 families cover typical exposed closet applications. Options include 1.6 gpf and high-efficiency 1.28 gpf. XL packages include installation hardware such as a sweat-solder adapter.

Urinal, exposed manual

Royal 180 and 186 families are the common exposed urinal choices. Flush volumes include 1.0 gpf for low consumption, 0.5 gpf for WaterSense targets when paired with a matching fixture, and 0.125 gpf for ultra-low systems where the fixture is rated for it.

Touch-free and concealed options

Royal is available as factory sensor models in exposed or concealed layouts. Sensor variants are offered in hardwired and battery forms, with a True Mechanical Override available on select models for code and facility preferences.

Selection guidance from our team

  • Match the valve to the fixture. Use the bowl or urinal manufacturer’s rated flush volume to maintain rinse performance and avoid splash or bounce-back.
  • XL package details. XL variants include the sweat-solder adapter and related hardware to speed retrofit work on copper supplies.
  • Materials and internals. Royal bodies use high-copper brass with chloramine-resistant diaphragm components for reliability in tough water conditions.
  • Compliance. Use the ADA non-hold-open handle. For WaterSense claims, pair 1.28 closet valves or 0.5 urinal valves with WaterSense-rated fixtures. Follow local code for mounting height and vacuum breaker positioning.

How to order Royal correctly

  • Choose the valve family for the fixture type and spud location
  • Select the rated flush volume to match the bowl or urinal
  • Pick actuation style and exposed vs concealed layout
  • Confirm stop type, tailpiece length, and vacuum breaker tube length
  • If selecting a sensor configuration, match power method and any required override
  • Add installation accessories required by local code or facility standards

Common retrofit scenarios

  • Replacing exposed manual valves on copper supplies using an XL package with a sweat-solder adapter
  • Upgrading manual Royal bodies with exposed sensor models where hands-free operation is desired
  • Reducing urinal volume from 1.0 to 0.5 gpf only when the fixture is rated for the lower volume
  • Verifying vacuum breaker tube length, spud coupling size, and tailpiece adjustment during replacement to avoid fit issues

Popular model callouts

  • Royal 111 1.6 gpf or 1.28 gpf for exposed closet applications
  • Royal 180 1.0 gpf for standard low-consumption urinals
  • Royal 186 0.5 gpf for WaterSense urinal applications, with 0.125 gpf available for compatible fixtures
  • Royal exposed or concealed sensor configurations for hands-free operation, with optional True Mechanical Override

Maintenance and parts

Royal shares a broad ecosystem of service parts across Sloan diaphragm valves. Common items include diaphragm kits for specific flow rates, handle repair kits, vacuum breaker assemblies, angle stop components, and cover tubes with wall flanges. Most maintenance can be completed from the front of the valve with standard tools to minimize downtime.

Can I convert existing Royal manual valves to sensor operation
Yes. Select factory sensor Royal models or replace compatible manual bodies with exposed or concealed sensor versions that match your power method and code needs.

What are the most common Royal urinal flush volumes
1.0 gpf is common for low-consumption urinals. 0.5 gpf is used for WaterSense targets when matched to the right fixture. 0.125 gpf is available for ultra-low designs with compatible fixtures.

Do Royal XL packages include installation hardware
Yes. XL versions include a sweat-solder adapter kit and related hardware that simplify retrofit work on copper supplies.
