'''Clamshell Gates''' are typically used for cutting off material flow when loading hopper, bins and other containers and are suited for the unrestricted bulk discharge of bulk materials out of silos and bunkers. In an open position the clams are situated outside the area of material flow thus improving the life cycle of the clamshell due to reduced wear. | '''Clamshell Gates''' are typically used for cutting off material flow when loading hopper, bins and other containers and are suited for the unrestricted bulk discharge of bulk materials out of silos and bunkers.

The clamshell gate is designed so that most material tends not to push the gates open under normal operating conditions resulting in a fail safe gate should air pressure be lost to the pneumatic cylinder. Cylinder mounted limit switches can be fitted as optional extras. | The clamshell gate is designed so that most material tends not to push the gates open under normal operating conditions resulting in a fail safe gate should air pressure be lost to the pneumatic cylinder.

Valve options include stainless steel construction and fitting of gear covers, linear electric actuators and mechanical limit switches. | Valve options include stainless steel construction and fitting of gear covers, linear electric actuators and mechanical limit switches. | ||
