Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a PTFE seal and a PVDF body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Threads and a hex nut below the handle allow you to install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.

With seats that can stand up to aggressive and corrosive solutions, these valves are often used in chemical-processing applications. They bolt to flanges for adjusting and regulating flow in flanged pipelines.

Wafer valves must be sandwiched between two flanges; they have tabs or unthreaded holes to help align the valve between the flanges.

Lug valves can be sandwiched between two flanges or bolted directly to a single flange for servicing one end of the pipeline without depressurizing the other side. They have threaded flange holes with a hole pattern that matches ANSI flanges of the same pipe size.

Lockable lever handles have 10 flow-adjustment positions. The handle can be fixed in place with a padlock (not included).

Wheel handles open and close with multiple turns, providing fully adjustable 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.

Made of alumina ceramic components that resist most chemicals for a long time, use these valves to manually adjust the flow of extremely corrosive fluids—they connect to pipe flanges with bolts. Their ceramic components are harder than stainless steel and withstand abrasion from particles in waste acids and other chemical slurries, which are common in power plants, paper mills, and refineries. They also handle vapor bubbles in systems that have big pressure changes. To protect the ceramic from impact, while also resisting corrosion, their housing is stainless steel. These valves are also known as ball valves.

Adjust the flow of fluids by hand using the lever, which opens and closes the valves in 10% increments. If you want to replace the lever with an actuator, use the mounting holes, which meet ISO 5211 dimensional standards. These valves meet ANSI Class IV for tight shutoff and have a leakage rate of less than 0.01%.

Full-port valves do not restrict flow when fully open, so they have minimal impact on pressure in that position.

Standard-port valves slightly restrict flow when fully open, which reduces abrasion to downstream components. However, they create a larger pressure drop than full-port valves.

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.
