Scale Valve: Type Twin Scale Valve

Procol twin vane divertors (scale valves) are designed to transfer product directly from a pneumatic conveying system into a weigh hopper. They are also used in multi-silo installations, allowing a single conveying line and venting system to serve multiple silos, delivering significant cost savings.

The valves can be supplied in a range of materials and with optional flanged connections. In operation, both vanes are initially set in the lower position, isolating the weigh hopper from the conveying system while allowing product and air to enter the hopper.

As the product enters the hopper, air is separated and returned to the conveying line via a return port in the valve base. Once the target weight is reached, the vanes snap back to the lower position, isolating the hopper and allowing excess product to be returned to the main storage silo through the conveying system.
