Lawler Series 4000 Model 4220 Washdown Shower Mixing Valve

The Lawler Series 4000 Model 4220 Type T Shower Mixing Valve uses a sensitive thermostatic element that automatically responds to temperature and pressure variations by proportioning hot and cold water flow to help maintain a consistent outlet temperature.

This washdown configuration includes two tempered water outlets. The filler supply is equipped with a shutoff valve and vacuum breaker, while the washout outlet includes a shutoff valve, vacuum breaker, washout hose, and hose hook.

The valve uses a liquid-filled thermostatic motor, lead-free brass body construction, replaceable corrosion-resistant components, and a sliding piston control mechanism with stainless steel piston and liner components. Assemblies with downstream shutoff devices include union-end stop and check valves with removable strainers on each inlet.
