Design Feature

AFFCO valve, High Performance double eccentric 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

Over travel limits design for disc position

Wafer, Lug and flange versions

Bottom split ring positioning and blow-out proof design

Bidirectional sealing design

Elastic metal seat design, zero leak tightness testing more than 10000 times

Top flange according to ISO5211, directly for mouting actuators

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

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

Fire safe design of superior performance prolongs service life, conforms to the requirements of the fire test standards

Clamp backing pin design, reliability and easy maintenance

A wild range of applications from vaccum to ultra high pressure service, and from low to ultra high temperature service. Suitable for severe process
