Easy-to-Install On/Off Valves with Solder-Connect Fittings
- Valve Type: Ball
- For Use With: Air, Oil, Steam, Water
- Seal Material: Fluoroelastomer Rubber
Install these valves in lines that require frequent maintenance or cleaning. They give you a leak-tight, permanent solder connection to your tubing with the ease of a union fitting to install them without disrupting your line. Before you install the valve, slide the union fitting over your tube, then solder the solder fittings to your tubing.
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.

Solder-Connect On/Off Valves with Gauge Port and Strainer
- Valve Type: Ball
- For Use With: Oil, Water
- Seal Material: PTFE Plastic
- Specifications Met: ASME B16.22
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.
