Common questions on this part
In a butterfly valve, the center of the disc remains in the middle of the flow path, creating a shelf where bulk powders bridge, pack, and jam during closing. The spherical disc valve rotates entirely out of the flow stream into an offset cavity, leaving a 100% open chute. On closing, its spherical geometry cuts through the solids column without packing material against the seat.
Yes. The standard 4M-SDV is rated for pressure holding up to 10 kg/cm² (142 PSI), making it ideal for dense-phase and dilute-phase pneumatic conveying blow pots and receiver hoppers.
