Flanged On/Off Valves
Bolt these valves to ANSI flanges. Their lockable lever handle can be fixed in place using a padlock (not included). These valves have four mounting holes for attaching an actuator.
316 stainless steel valves are more corrosion resistant than cast iron or steel valves.
Standard-port valves slightly 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.

Flanged Gradual On/Off Valves
Rising Stem, and
Eight 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.
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.

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.
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.
