Description
This 3-way L-port ball valve is designed for diverting flow between multiple lines within Corzan CPVC pipework systems. The L-port configuration allows directional control between two outlets, making it ideal for applications requiring flow changeover, isolation or simple distribution without complex pipe arrangements.
Manufactured from high-performance CPVC and fitted with FPM seals, the valve offers excellent resistance to aggressive chemicals, elevated temperatures and industrial process fluids. Its true union construction allows the valve body to be removed easily from the pipeline, simplifying inspection, seal replacement and routine maintenance without disturbing adjacent pipework.
The patented DualBlock system securely retains the union nuts, helping maintain joint integrity under vibration or thermal movement. Combined with the Seat Stop ball seat carrier, the valve allows fine seat adjustment and axial load compensation without draining the system, delivering reliable shut-off and long service life in demanding environments.
