About On/Off Valves

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 and strainers prevent backflow and trap debris.

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.

Gas Mixers

Threaded Inlet

Unthreaded Inlet

Supply the right amount of air and gas to burners. These mixers slip over the end of a burner pipe and attach with the included set screw. All have adjustable air openings. To choose your mixer and valve, determine the size of your burner pipe and gas input connection. Select about measuring pipe for more information.

Connect one end of a mixing valve to the mixer and thread the other end into your gas line.

Easy-Clean Threaded Diverting Valves for Chemicals

Valve Type: Ball
For Use With: Air, Ammonia, Butane, Carbon Dioxide, Citric Acid, Deionized Water, Diesel Fuel, Ethanol, Ethylene Glycol, Fuel Oil, Isopropyl Alcohol, Kerosene, Natural Gas, Nitric Acid, Oil, Oxygen, Phosphoric Acid, Propane, Salt Water, Soap Solutions, Sodium Hypochlorite, Sulfuric Acid, Toluene, Water
Ball Material: Polypropylene Plastic
Seal Material: Fluoroelastomer Rubber

There’s no need to unbolt these valves for cleaning—remove the handle and slide the valve apart for inline access to internal components. Also known as elliptical valves, they have a fluoroelastomer seal and a polypropylene body for diverting flow in chemical-processing applications. All are full port, so they do not restrict flow.

Valves with any port inlet can use any port as an inlet or outlet. Turn the handle to direct flow from the inlet port to one outlet port at full capacity, direct flow to both outlet ports simultaneously at reduced capacity, or shut off flow completely.
