Design Feature

AFFCO valve, High Performance butterfly valves are engineered to meet the standard requirements of most project specifications, and a range of additional features and options make our valves suitable for even the most severe conditions. Low torque enables the most cost-effective actuation operations, all AFFCO High Performance valve models have been cycle tested to ensure good seating performance even after 100,000–200,000 times open and close.

Accordance with industrial standard API/EN/ANSI/JIS/GB

Ultra high machining accuracy and elastic seat design ensures lower torque value

Wafer, Lug and flange versions

Blow-out proof stem design

Bidirectional sealing design

Double eccentric design reduces wearing on the seat and ensures bidirectional sealing under rated pressure range

Top flange according to ISO5211, directly for mouting actuators
