To install on the discharge outlet of a silo and at the inlet of pressure blowers.
These valves perform a double function: They help discharge the product and they also isolate the conveyor bucket keeping it hermetically sealed.
The disc resembles a bell (a cone with a circular base) and it achieves a perfect hermeticity against the body even when working with very abrasive solid particles.
These valves are mainly used on the pneumatic transport of powder-type fluids, mounted in between the discharging silo and the propelling bucket.
Bell valves are used as an isolating element.
Sizes range from DN100
