Flanged On/Off Valves
With Four Bolt Holes
With Eight Bolt Holes
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. Standard-port valves slightly 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.

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.
