CRISPIN KK0642 CI 150B 6IN 504A NBR 150F Butterfly Valve

The CRISPIN K-FLO KK0642 butterfly valve is a 6-inch valve with a cast-iron (CI) body, designed for precise throttling and reliable inline isolation in mid-size piping systems. This model carries the 150B designation and is part of the KK0642 family, aligned with the 504A specification, and it uses NBR as the sealing material in its assembly. The 150F flange reference defines the standard connection footprint for this unit, ensuring compatibility with matching flanges and gaskets in process lines that require a proven, fixed-geometry butterfly valve. With a 6-inch diameter, CI construction, and the documented identifiers KK0642, 150B, 504A, NBR, and 150F, this valve presents a clearly defined option for buyers seeking a traceable Crispin component built for solid performance in flow control.
