Chemical compatibility must be determined by the customer based on the conditions in which the product is being used, including the presence of other chemicals, temperature, and consistency.

Protect personnel and equipment in the presence of diesel fuel, fuel oil, gasoline, and kerosene. Fire-tested to meet American Petroleum Institute (API) 607, these valves are designed to securely isolate fluid and prevent the spread of fire. They have a lockable handle that can be fixed in place using a padlock (not included).

Standard Port — Standard-port valves slightly restrict flow.

Flow Coefficient (Cv)—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.
