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.

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 Balancing Valves

- Valve Type: Ball
- For Use With: Water
- Seal Material: EPDM Rubber
- Specifications Met: CSA Certified
Thread these balancing valves onto pipe—they help you measure the pressure differential across the valve as well as change the flow rate to components in your system. Sometimes called circuit setters, they’re used in HVAC systems and other systems that require even flow distribution. To see what percentage they’re open, there’s an arrow on these valves that’s connected to their measuring plate. Readout ports on both sides let you attach flow measurement tools, such as pressure gauges and probes, which help you track how much the valves reduce flow. Open these valves to a saved percentage by using their memory shutoff function.
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.

Diverting Valves with Fire-Fighting Hose Fittings


- Valve Type: Ball
- For Use With: Water
- Seal Material: Buna-N Rubber
Control the flow of water in two directions from a single source—these diverting valves have two balls and handles for independent operation of each outlet. They can direct flow to one side outlet at full capacity while shutting off flow to the second side outlet, direct flow to both side outlets at reduced capacity, or shut off flow to both side outlets. Valves have a brass body for good corrosion resistance. They are for use with fire-fighting hose.
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.
Male NPSH (National Pipe Straight Hose) threads are compatible with female NPSH threads. Female NPSH threads are compatible with male NPSH, NPT, NPTF, and NPSM threads.
