Flanged On/Off Valves for Chemicals
Bolt these valves to ANSI flanges—they meet ASME dimensional standards. They have a plastic body and a seal that withstand aggressive and corrosive solutions in chemical-processing applications.
Glass-filled vinyl ester valves stand up to a wide variety of harsh acids and solvents. You can rely on them for repeated use, changes in pressure and flow rate, and hot and cold conditions.
Valves with a lockable lever handle can be fixed in place with a padlock (not included). They give you more leverage than short lever handles, so you can quickly open and close the valve with minimal effort.
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.
