The Mosites C30N Butterfly Valve was developed to fill an industry need for a high cycle, fully elastomer lined butterfly valve. If your processes involve chemicals, slurries, water, air or vapors, the C30N can solve your control problems. Incorporating the same unique features as the C30, the C30N meets API 609 and MSS-SP 67 laying length (face-to-face) dimensions for quick replacement of standard butterfly valves.
