Slide copper pipe into the solder-connect fittings on these valves and weld for a strong, permanent connection. They’re often used for remote on/off control in heating and cooling systems. All operate on electricity to automatically start and stop flow. Valves do not require a minimum pressure drop between the inlet and the outlet for operation. They are normally closed unless actuated. All are standard port, so they slightly restrict flow.

The actuator is directly mounted to the valve body to minimize movement and reduce wear. The manual override allows you to operate the valve during power outages.

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.

A threaded union on these valves makes them easy to install and remove without disrupting your line. They thread together or apart with only a turn to the union fitting, unlike other threaded on/off valves that require repositioning your pipe or valve. The union fitting slides over your pipe, and the threaded fitting sits inside. They’re often connected to tanks in control rooms and to radiators. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops. With a nonrising stem, the handle stays in the same place whether these valves are open or closed.

Brass valves have good corrosion resistance. They also have a more polished look than bronze valves.

Bronze valves resist corrosion better than brass valves, including from salt water. They’re also stronger.

Monitor and maintain flow quality from a single valve—these valves have a gauge port, strainer, and drain built in. A gauge port gives you a spot to add a gauge to monitor pressure without stopping flow. The strainer traps debris to prevent blockages, while the drain releases excess liquid and debris. They’re a good choice for lines that require frequent maintenance or cleaning. A threaded union makes these valves easy to install and remove without disrupting your line. They thread together or apart with only a turn to the union fitting, unlike other threaded on/off valves that require repositioning your pipe or valve. The union fitting slides over your pipe, and the threaded fitting sits inside. These valves are full port, so they do not restrict flow.

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.
