GENERAL INFORMATION

Theory of Operation

A.HV Series

HV Series valves are rotary action, linear travel gate valves. The gate carriage moves in the valvebody on a set of wheels, moved back and forth by a manual or pneumatically-actuated valve stem. To close the valve, the carriage moves forward on wheels until it reaches the end of the valve case.When the carriage stops, the sine waved rotary linkage continues to travel and extend. The gatedoes not move forward, only upward toward the port seal surface. There is no abrasion or damage to the O-ring. The gate moves up to the port into its sealing position. The O-ring is compressed, making a leak-tight seal. The sine waved rotary linkage continues to move forward until the link- age reach bottom dead end and locks, providing positive closure protection in the event controlpower, or air pressure, is lost.
