AAP Wafer Butterfly Valve, 14"

This AAP NBR wafer butterfly valve has a cast iron body, a nickel plated ductile iron disc, an NBR seat and a gear operator. It is supplied in 5 sizes from 14" (350mm) to 24" (600mm).

A butterfly valve turns a disc on a central stem through a quarter turn: with the disc in line with the flow the valve is open, and turned across the flow it is closed. The resilient seat is the soft liner the disc seals against. The resilient seat butterfly valves are compact, give bubble tight shut-off and have good regulating capabilities. The wafer body suits most international flanges, including AS 2129, BS 10, ANSI, DIN and JIS, in sizes 50mm to 300mm. It is made for inline service and relies on a flange on each side of the valve to hold it in the pipeline. That flange match covers 50mm to 300mm only, so check the hole pattern of your 350mm to 600mm flanges against the bolt dimensions.

Key specifications

Choosing the right option

Choose the size to match your pipe, and choose wafer or lugged to suit how the valve will be mounted. Check the seat material against your fluid and temperature. These sizes come with a gear operator, so check the clearance around the operator and handwheel in your pipework.
