Details
ANSI/FCI 70-2-2021 establishes six classes of seat leakage for control valves. Also defined are specific test procedures to determine the appropriate class. Included are classes commonly associated with double-port, double-seat or balanced single-port control valves with a piston ring seal or metal-to-metal seats, commercial unbalanced single-port, single-seat and balanced single-port valves with extra tight piston rings or other sealing means and metal-to-metal seats, valves for critical applications where the control valve may be required to be closed, without a blocking valve, for long period of time, and resilient seating control valves with "O" rings or similar gapless seals, among others.
