RULA design, manufacture and supply clam shell valves for a wide range of applications
Description
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. Types of actuation Actuation can be pneumatic or hand operated units Design Features Cost competitive if compared to other isolation solutions Material of construction specifications - Bodies: SANS 50025 Grade S 355 JR plate - Clams: SANS 50025 Grade S 355 JR plate - Gears: SANS 50025 Grade S 355 JR plate or wear resistant steel - OR as per client requirements and specifications.
