2 Pieces Ball Valve
A two-piece forged ball valve consists of two main body sections that clamp together around the ball assembly. While offering a more compact design than three-piece valves, this construction presents maintenance challenges – servicing requires complete removal from the pipeline. The valve's sealing performance heavily depends on proper bolt torque at the central connection, where inadequate tightening can lead to leaks.
Due to its structural design, this valve type is not recommended for high-pressure applications (typically limited to <600 psi). The permanent body connection makes internal inspection and part replacement difficult compared to modular three-piece designs.
Best suited for
General industrial service
Low to medium-pressure systems
Applications where space constraints exist
Non-critical processes with infrequent maintenance needs
While cost-effective for basic applications, engineers should consider three-piece designs when anticipating regular maintenance or requiring higher pressure ratings.
