Description
The FK Butterfly Valve with lever operation and EPDM seal is designed for reliable on/off isolation and controlled throttling in larger-diameter Corzan CPVC pipework systems. Its butterfly configuration provides efficient flow control with minimal pressure drop, making it particularly well suited to high-flow industrial applications.
The valve features a corrosion-resistant CPVC disc combined with a robust GR-PP body, delivering excellent chemical resistance and long-term durability in aggressive environments. An EPDM liner provides dependable sealing performance for a wide range of industrial liquids, including water, effluent, acids and alkalis.
Lever operation incorporates a locking mechanism with multiple ratchet positions, allowing the valve to be set securely for flow regulation as well as full open or closed service. The full flanged body design includes oval bolt holes and centring inserts, enabling compatibility with multiple flange standards and simplifying installation.
