About Backflow-Prevention Valves

About Flanged Flow-Adjustment Valves

Flanged Flow-Adjustment Valves

Also known as butterfly valves, these 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 can be fixed in place with a padlock (not included).

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.

Specifications Met: ANSI B16.10, MSS-SP-25, MSS-SP-67

Upgrade industry standard flanged gate and globe valves for quicker flow-adjustment capabilities—these have the same end-to-end length as valves of the same pipe size to swap out easily. Bolt them to flanges for adjusting and regulating flow in flanged pipelines. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 5/16”. These valves are lug style, so they 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.

Flanged Flow-Adjustment Valves for Chemicals

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.

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.
