Why choose manual worm gear flanged butterfly valves
Recently, a batch of DN100 manual flanged butterfly valves from Jinbin Valve Factory have completed the production and testing process, successfully packed and shipped, and will be shipped to the destination, providing key support for the construction and operation of industrial pipeline systems.
The following describes the differences and advantages of manual worm gear 4 Inch butterfly valve and other operating modes of butterfly valves.
A. Compared with electric butterfly valves
1. Operating cost: Manual worm gear butterfly valve does not need power supply and electric actuator and other equipment, low cost input, easy installation, especially suitable for no power supply or cost-sensitive places.
2. Maintenance: simple structure, fewer parts, low maintenance cost, low probability of failure, and no professional electrical knowledge is required during maintenance.
3. Control accuracy: Although it can not achieve accurate remote automatic control and flow regulation like the electric butterfly valve, it can meet basic needs in some occasions where the flow control accuracy is not high.
B. Compared with pneumatic butterfly valves
1. Power source: Manual worm wheel butterfly valve does not rely on compressed air, no need to equip air compressor and other air source equipment, can be used in a place without air source, and is not affected by air source pressure, gas volume and other factors.
2. Use environment: pneumatic butterfly valve in low temperature, high humidity and other harsh environment, improper air source is easy to lead to failure, and manual worm gear butterfly valve is less affected by environmental factors, a wider range of application.
3. Maintenance requirements: The pneumatic actuator of the pneumatic butterfly valve needs to regularly check and maintain seals, filters, etc., in contrast, the maintenance workload of the manual worm gear butterfly valve is less and the maintenance difficulty is low.
C. Compared with handle butterfly valves
1. Operating torque: The handle butterfly valve is operated directly by the handle, for large caliber or high pressure pipeline valves, the operation is laborious, and the manual worm gear butterfly valve is driven by worm gear and worm, saving labor, and can easily open and close large caliber and high pressure valves.
2. Flow control: worm gear drive can make the butterfly plate rotate more smoothly and slowly, which is conducive to accurate control of flow, and the handle butterfly valve is difficult to do this.
3. Positioning ability: The worm gear reducer of the manual worm gear butterfly valve can make the butterfly plate stop at any position to achieve flexible positioning, and the handle butterfly valve can usually only be fully opened or fully closed, which is difficult to accurately locate in the middle position.
