Bolt these valves to pipe and pump flanges to start and stop flow before pump maintenance without draining your system. They attach to industry-standard two-bolt flanges on circulation pumps from manufacturers such as Bell and Gossett, Taco, Grundfos, and Armstrong. All are full port, so they do not restrict flow.

Valves with T-handles resist accidental movement when bumped or snagged.

Valves with 1/2" dia. bolt holes fit standard pumps. Valves with 5/8" lg. x 1/2" wd. bolt holes fit both standard and high-velocity pumps.

Monitor and maintain flow quality from a single valve. These valves have gauge ports, a strainer, and a drain built in. Gauge ports let you take pressure, temperature, and other measurements in your line. A strainer traps debris to keep it out of your system, and a drain lets you release fluid and debris. These valves are full port, so they do not restrict flow.

Thanks to their solder-connect union fitting, these valves are especially useful in lines that require frequent maintenance and cleaning. Slide the union nut on the tube and solder the solder-connect fittings to your line for a permanent, leak-tight connection. You can then connect and disconnect the line with a turn of the union fitting.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Crimp these valves to metal tubing for a permanent, leak-tight connection that doesn’t require heat or soldering. All are full port, so they do not restrict flow. Choose a crimping tool based on your valve's compatibility: Viega ProPress or Viega MegaPress.

Valves with EPDM rubber seals are often found in water-processing lines, fire sprinklers, and heating and cooling systems. Compared to valves with Buna-N rubber seals, these valves better handle soapy solutions and temperature fluctuations.

Double-tee valves isolate flow between two pipe ends—no additional fittings needed. Fewer fittings in your line mean fewer leak paths to worry about.

Valves with GHT threads are compatible with any garden hose and fittings. They come in one standard size. All include a cap to protect against dirt and debris. It's connected to the valve to keep it from getting lost when the valve is in use.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Certified to meet NSF/ANSI 61, these valves control the flow of drinking water. With universally compatible threads, they’ll connect to any garden hose or garden hose fittings. The included hose cap protects them from dirt and debris.

Full-port valves do not restrict flow.

Standard-port valves slightly restrict flow.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

For a permanent, leak-tight connection that doesn’t require heat or soldering, these valves have press-connect fittings that crimp to copper tubing. Install them with a press-connect crimping tool (sold separately). These valves meet NSF/ANSI 61 for use in drinking water systems. All are full port, so they do not restrict flow.

Valves with GHT threads are compatible with all standard garden hoses and fittings. They come with a hose cap to keep dirt from entering the valve; it’s attached with a chain to keep it from getting lost when not in use.

Install tee valves in your line to drain or fill your system without disassembling connections or adding fittings. They help minimize leak points.

Bronze valves are stronger and more durable than brass valves.

Solder these valves to metal tubing for a permanent, leak-tight connection. They meet NSF/ANSI 61 for use with drinking water. All are full port, so they do not restrict flow.

Tee valves can be installed in your line to drain or fill your system without disassembling connections or additional fittings. They help minimize leak points.

Bronze valves are stronger and more durable than brass valves for a longer life.

Valves with GHT threads are compatible with any garden hose and fittings. They come in one standard size. All include a cap to protect against dirt and debris. It’s connected to the valve to keep it from getting lost when the valve is in use.

Convert one faucet into two, four, or five outlets.

All valves have shut-off outlets, so you can start and stop the flow to outlets individually. You can also use the shut-off to release pressure or drain residual water after disconnecting hose. Some valves also have open-flow outlets in addition to shut-off outlets. Open-flow outlets don't give you any flow control—they work like standard outlets.

Plastic valves are lighter in weight than metal valves, but they’re not as durable. Zinc valves are stronger and more resistant to wear and tear than plastic valves. Brass valves are stronger than plastic, zinc, and aluminum valves. Aluminum valves resist the highest pressures.

Contoured lever handles give you a better grip—choose them if you’ll be wearing gloves often or if they’re in an area where they’ll get wet and slippery. Toggle-switch handles easily flick on and off like a light switch.

Valves with TPR coating protect your hands by keeping the valve’s surface from getting too hot or cold.

Valves with a support brace can be secured against a wall for extra stability.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
