Description
The FK Butterfly Lever Operated Valve with FPM seal is engineered for demanding Corzan CPVC systems where aggressive chemicals, elevated temperatures or solvent-based media are present. Designed for both isolation and controlled throttling, the butterfly configuration provides efficient flow regulation with minimal pressure loss across larger bore pipework.
A corrosion-resistant CPVC disc is combined with a rigid GR-PP body to deliver long-term structural stability in industrial environments. The FPM liner offers superior resistance to oils, solvents and highly aggressive chemical fluids, making this valve particularly suitable for harsher process conditions where EPDM is not recommended.
The lever-operated handle incorporates a locking mechanism with multiple indexed positions, allowing the valve to be securely set for partial flow control or fully locked open or closed. A full flanged body with oval bolt holes and centring inserts ensures compatibility with multiple flange standards, simplifying installation and alignment.
