Product Description
This manual override gearbox from the SD series is a vital component of the automation control system, and it works in conjunction with the pneumatic actuator to accomplish its functions. One of the primary goals of this device is to facilitate the smooth working of valves such as butterfly valves, ball valves, piston valves, and other valves that require a 90-degree angular movement in order to open and close. In spite of the fact that the SD series gearbox is intended for manual operation, it is also suitable for use in circumstances where manual drive is required for mechanical products and automatic control systems. There are many different industries that can make efficient use of the SD series manual override gearbox. Some of these industries include the petroleum industry, the chemical industry, the pharmaceutical industry, the water treatment industry, power plants, and nuclear power establishments. In addition to supporting the operation of plug valves, butterfly valves, and ball valves with a 90-degree open position, it is specifically intended to assist the operation of various types of valves.
