Butterfly Valve – double offset (soft seat)
Butterfly Valve – KKD-81L
Centric Butterfly valve is a cost-effect compact solution for general purpose applications. With multiple rubber seats to choose from.
In a center lined butterfly valve, the stem is centered in the middle of the disc and the disc is centered in the bore.
In this type of valve, the disk first interacts with the seat at about 85° for a 90° rotation.
Center lined butterfly valves are widely used in low-pressure applications.
The lug body type of the butterfly valve design is identical to the 3-piece ball valve, where one end of the pipeline can be replaced without affecting the other side of the valve.
This can be accomplished using threaded inserts, flanges, and two sets of lugs (bolts) that do not use nuts so that each flange has its bolts.
It is not necessary to shut down the entire plant to inspect, clean, repair or replace the butterfly valve.
