Threaded On/Off Valves
Use these valves in general purpose applications such as those with water, oil, air, and inert gas.
Plated brass valves are more corrosion resistant than plain brass or bronze valves.
316 stainless steel valves have the best corrosion resistance.
Lockable handles can be fixed in place using a padlock (not included).
Short lever handles, lockable oval handles, and T-handles resist accidental movement when snagged or bumped.
Full-port valves do not 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.

Easy-to-Install Plastic Threaded On/Off Valves
A threaded union on these valves makes them easy to install and remove without disrupting your line. They’re a good choice for lines that require frequent maintenance or cleaning. 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. With a full port, these valves won’t restrict flow.
Made of plastic, they last longer than metal valves since the inside won’t corrode or pit. They’re also lighter in weight. PVC valves are commonly used in water lines. CPVC valves handle higher temperatures than PVC or polypropylene valves. They’re the best choice if your system connects to a heater.
Valves with a T-handle have a larger gripping surface than valves with a short lever handle, so they’re easier to turn when your hands are slippery.

Flanged On/Off Valves

Bolt these valves to ANSI flanges. Their lockable lever handle can be fixed in place using a padlock (not included). All have four mounting holes to install an actuator, so you can convert them from manual to automatic valves.
Steel valves stand up to corrosion better than cast iron valves. 316 stainless steel valves are more corrosion resistant than cast iron and steel valves.
Full-port valves do not restrict flow.Pressure class 150 valves are standard and work for most low-pressure applications.
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-to-Install Socket-Connect On/Off Valves for Chemicals

Streamline your installation and removal process. These valves give you the leak-tight permanent connection of a socket connect with the ease of fittings that come apart. Before you install the valve, slide the union fitting over your pipe, then insert the pipe into the socket fittings and bond with primer and cement. The union fittings allow the valve to be quickly removed where other socket-connect valves would require you to cut your pipe. A fluoroelastomer seal and plastic body withstand aggressive and corrosive solutions in chemical-processing applications. All valves have a T-handle that resists accidental movement when snagged or bumped. They are full port, so they do not restrict flow.
PVC valves are often used in mild chemical processing systems. CPVC valves resist heat better than PVC valves, so they’re a good choice for systems that connect to a heater. Lockable T-handles can be fixed in place using a padlock (not included).

Threaded Gradual On/Off Valves
Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.
Valves with a pull handle open and close faster than valves with a wheel handle. Also known as slide valves, they’re often used to control flow in air conditioning and ventilation systems. Valves with a wheel handle open and close with multiple turns, providing more controlled, shock-resistant flow than valves with a pull handle.
Valves with a rising stem lift the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem. Valves with a nonrising stem keep the stem in the same position whether they’re open or closed. They’re often used underground and in low-clearance locations.
Valves with threaded union stem allow you to maintain and repair these valves while they’re still inline—you can disassemble the stem so there's no need to unthread the pipe connections. Bronze valves resist corrosion better than brass valves. They’re also stronger.
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 Threaded Gradual On/Off Valves
Maintain and repair these valves while they’re still inline—you can disassemble the stem so there's no need to unthread the pipe connections. Also known as gate valves, they open and close gradually to prevent sudden starts and stops. Control the flow by turning the wheel handle multiple times. This gives you more control than a pull handle. Made of bronze, these valves have good corrosion resistance.
Valves with a rising stem lift the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem.

Flanged Gradual On/Off Valves

Nonrising Stem, and
Four Bolt Holes

Rising Stem, and
Four Bolt Holes
Bolt these valves to flanges. They gradually open and close to prevent system damage from suddenly starting and stopping flow.
Epoxy-coated cast iron valves are more corrosion resistant than plain cast iron or steel valves.
Wheel handles open and close with multiple turns, providing more controlled, shock-resistant flow than pull handles.
Nonrising stems stay in the same position whether the valve is open or closed. Valves with nonrising stems are often used underground and in other low-clearance locations.
Rising stems lift as the valve opens and lower as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a longer service life than valves with a nonrising stem.
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.
