Worm gear reducer connection
This is the direct mounting of the gearbox to the rotor shaft of the valve. The drive system consists of the following; the gearbox, and the motor. The installation of the motor and the gear require less space.
Chain gear connection
This is also known as a chain driven connection. The rotor and the gearbox are mounted on the side, driving the rotor shaft through a chain sprocket. This rotary valve drive system consists of a gearbox, chain, motor, guard, and sprockets. The sprocket size contributed to the speed of the system.
Direct coupling connection
This is a type of motor in which the load is connected directly to the motor. It consists of a shaft connecting a motor to a rotary valve. If there exists a mechanical coupling between the motor and the rotary valve along the shaft, then the drive system is known as a direct coupled drive or simply direct coupling. The coupling mechanism can either be a rigid one or a flexible one. Since the system has less parts, the energy dissipation is minimal.
Wide range of rotary valve models and configurations are available for different process conditions and physical properties of transferred bulk solids. According to process (silo, cyclone, jet filter, conveyor, pneumatic conveying system etc.) ; according to bulk material (fine powder, granule, abrasive, elastic, high temperature etc.)
Throughout the industrial sector, the use of a rotary valve is undeniable. Since its inception, its use in industries has progressively grown. Its utilization can range from food and pharmaceutical to agricultural and milling industries – nearly every industry out there makes use of it to its full capacity.
