Threaded On/Off Valves
Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.
Brass valves have good corrosion resistance to air, water, and oil. Full-port valves do not restrict flow. FM-approved valves are used in fire suppression systems. They help isolate parts of water supply systems in buildings and plants.
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.
- Valve Type: Ball
- For Use With: Air, Steam, Water
- Seal Material:
NPT Female × NPT Female: Fluorelastomer Rubber
NPT Female × NPT Male: PTFE Plastic - Specifications Met: See table
Lockable handles can be fixed in place using a padlock (not included).
Oval handles have the largest gripping surface of any handle type, so they’re the easiest to grip when slippery.

Threaded On/Off Valves with Gauge Port
- Valve Type: Ball
- For Use With: Air, Water
- Seal Material: Fluoroelastomer Rubber
- Specifications Met: C-UL Listed, CSA Certified, CSA-US Certified, UL Listed
Attach a gauge to the side port on these valves to monitor pressure, temperature, and other measurements in your line. The port can also be used to drain and divert liquid. These valves are full port, so they do not restrict flow.
Lockable handles can be fixed in place using a padlock (not included).
Oval handles have the largest gripping surface of any handle type, so they’re the easiest to grip when slippery.
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.

Easy-Maintenance Socket-Connect On/Off Valves
Clean and maintain these valves without removing welded connections. To create a permanent, leak-tight connection, insert unthreaded pipe into the socket and weld. These valves have a three-piece bolted body that disassembles inline, which makes it easy to access internal components. They also have lockable handles that can be fixed in place with a padlock (not included). All are full port, so they do not restrict flow.
316 stainless steel valves resist corrosion better than steel valves.
Oval handles are less likely to shift than lever handles if they’re bumped or snagged, so you won’t accidentally adjust the 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.
Maintenance kits (sold separately) include seats, seals, and stem packing to replace worn parts inside valves.
- Valve Type: Ball
- For Use With: Air, Argon, Helium, Neon, Oil, Water, Xenon
- Seal Material: PTFE Plastic
