Engineered for reliable pneumatic transfer.
The function of the RULA clamshell gate valves are suited for the unrestricted bulk discharge of bulk materials out of silos and bunkers. The clamshell gates are fitted with meshing gears and are laser cut to suit the size of the gate. Clamshell gates 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 reducing wear and improving the life of the clamshell gate valve. 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.
