Threaded Temperature-Regulating Valves for Water

For Use With: Water
Max. Inlet Temperature: 180° F for Brass, 200° F for Copper
Max. Inlet Pressure: 150 psi

These valves blend hot and cold water to automatically maintain a set outlet temperature. Adjust the outlet temperature within the range.

Valves with safety shut-off restrict flow down to a drip if your cold water supply shuts off.

Internal check valves prevent backflow. Strainers trap debris.

Temperature-Regulating Valves with Compression Fittings for Water

For Use With: Water
Max. Inlet Temperature: 110° F
Max. Inlet Pressure: 70 psi

Designed for use on tubing lines with a constant inlet temperature and pressure, this valve has compression fittings that bite down on hard metal and plastic tubing for a secure seal. Manually turn the lever to blend hot and cold water to maintain the set outlet temperature. Tighten the adjustment screw on the lever to prevent unintentional temperature changes. Valve has an internal check valve to prevent backflow. Body is chrome-plated brass for good corrosion resistance and a decorative finish.

Temperature-Regulating Valve Systems for Water and Steam

For Use With: Water, Steam
Max. Inlet Pressure for Water: 125 psi
Max. Inlet Pressure for Steam: 80 psi

Commonly used in washdown applications, these systems include a temperature-regulating valve with an internal check valve and vacuum breaker to prevent backflow, two ball valves for manual control of the water supply, a dial thermometer that displays the outlet temperature, and a hose rack for storage.

Valve with safety shut-off restricts flow down to a drip if your cold water supply shuts off.

Manually activated valves give you independent control of hot and cold water supply.

Temperature-driven valve maintains your set temperature by adjusting flow in response to the water supply temperature.

Valve with a chrome-plated bronze body is more corrosion resistant than valves with a plain bronze body.

Valve with a 316 stainless steel body is has the best corrosion resistance.

Optional hose (sold separately) has a trigger spray nozzle.

303 stainless steel nozzle is more corrosion resistant than a bronze nozzle.
