Mastering Tempered Water Delivery #
Lawler Manufacturing’s master controllers are designed exclusively to help you achieve safe, precise tempered water within domestic plumbing systems. Our premiere master controllers rely on our patented single valve technology, giving you maximum space, maintenance, performance, and cost benefits.
Lawler’s mastering of tempered water delivery offers more protection and more choices.
When you specify Lawler master controllers, you get Three-Way Protection™:
- Lawler Thermostat Protection – protects against runaway temperatures
- Lawler Hot Supply Protection – protects against thermal shock
- Lawler Cold Supply Protection – protects against scalding
Lawler’s Master Controllers Deliver More Choices.
When you specify Lawler Master Controllers, you get the choice of:
- Capacity and flow range
- Temperature range and set point
- Finish, cabinetry, and piping configuration
- Thermostatic (T) or T/P (Thermostatic/Pressure-Balancing)
800 SERIES® #
The 800 Series® High-Low Master Controllers
Delivering Tempered Water through a Single Valve – over a Wide Range of Flows
Lawler’s 800 Series® High-Low Master Controllers deliver precisely maintained tempered water (±3°) over a wide range of flows. Lawler’s patented single valve high-low technology does “the same work better” than two-valve systems with much larger footprints, more moving parts, and maintenance complexities.
Every Lawler 800 Series® Valve Features:
- ASSE 1017 Approval
- Three-Way Protection™
- Powerful Liquid Motor & Rugged Stainless Steel Piston and Liner
- Tamper-resistant Control Adjustment
- Full In-Line Maintenance
- Maximum Rough-in Flexibility
- Inlets fully rotatable
- Outlets fully rotatable in 90° increments

Lawler’s Model 61® #
Three-Way Protection™ at Low-to-Mid-Range Flows
Specifiers rely on Lawler’s Model 61® to deliver precisely-controlled tempered water while providing Three-Way Protection™. The valve’s patented design delivers the safety and performance of a Lawler master controller in a small valve.
Accurately regulating flows within ±3˚, Model 61® is effectively used for metered and hands off wash basins, barrier free facilities, industrial and/or laboratory processes, as well as individual or dual showers. With Lawler’s Model 61®, there’s no need to settle for over-sized master controllers, or under-performing small controllers that don’t deliver Three-Way Protection™.
Lawler’s Model 66® #
Dependable Tempered Water for Medium to Large Capacity Applications
Lawler’s Model 66® meets your specification for efficiently mixing large quantities of hot and cold water while delivering Three-Way Protection™. The largest 66® valve can flow up to 200 GPM and accurately maintain outlet temperature within ±3°. Specifiers use Lawler’s Model 66® for applications such as group showers, progressive or zone showers, and multiple wash bowl systems.
Lawler’s Model 67® #
Controlling temperatures to within ±1.5°
Thermostatic & Pressure Balance Performance at Low-Flow Rates
Like the Model 61®, Lawler’s Model 67® delivers tempered water with Three-Way Protection™ at low-flow rates. But the 67® gives you two additional features – temperature control to within ±1.5°, and an independent pressure balance section, which means the Model 67® is a true T/P valve. Lawler’s Model 67® helps you achieve the highest possible tolerances in temperature control at extremely low-flow rates.
