The valves are similar in design to Procol PC Diverter Valves. To ensure consistent weighments the vanes are operated by twin pneumatic actuators which operate simultaneously to affect a snap action cut-off.
Various material options are available and the valves can be supplied with flanged connections if required.
Operating Method
The valves are initially set with both vanes in the lower position. this isolates the weigh hopper from the conveying system and allows product to pass over the hopper.
When the valve is operated the vanes move to the raised position which allows product and air to enter the weigh hopper. The product and air separate in the hopper and the air is returned to the conveying line via the return port in the valve base.
When the correct weight is reached the vanes snap to the lower position which again isolates the hopper from the conveying line and allows excess product to be returned to the main store silo via the conveying system.
