SD series Manual Declutchable Gearbox

Product Description

The SD series Manual Declutchable Gearbox is an essential component of the automation control system, working in concert with the pneumatic actuator. The main objective of this device is to enable the smooth operation of butterfly valves, ball valves, piston valves, and other valves that require a 90° angular movement for opening and shutting. The SD series Manual Declutchable Gearbox is designed for manual operation, but it can also be used in situations where manual drive is needed for automatic control systems and mechanical products. The SD series Manual Declutchable Gearbox is highly versatile and can be effectively utilised in various industries such as petroleum, chemical, pharmaceutical, water treatment, power plants, and nuclear power. It is specifically designed to support the operation of 90-degree open ball valves, butterfly valves, plug valves, and other types of valves.

Product Features

1.The SD series Manual Declutchable Gearbox has a small size, is light in weight, has a well-thought-out design, and features a contemporary style.

2.The SD series Manual Declutchable Gearbox provides a range of output torque options and pneumatic actuators that may be readily paired with different valves.

3.SD series Manual Declutchable Gearbox connection adheres to the ISO5211 standard, featuring a square tenon on the upper part and a square hole on the lower part. The high torque mechanism is equipped with connection ratios of 320:1 and 450:1. It features many key holes that enable users to choose the appropriate position of the product for the valve body according to their specific needs.

4.The upper boundary pin can be elevated to automatically spin the eccentric device either 180° or 90°, allowing for pneumatic or manual operation.

5.SD series Manual Declutchable Gearbox is equipped with a unique lubricating grease upon shipment from the factory. Once assembled with the valve and pneumatic actuator, it is securely sealed, offering protection against dust and water, and meeting the IP65 standard.

Product Advantages

 In comparison to other options, the JIMAI Declutchable gearboxn provides the following benefits:

1.Worm Material: JIMAI utilizes ASTM5140 as the worm material, significantly enhancing the shaft durability.

2.Input shaft material: JIMAI utilizes ASTM5140 for the input shaft, significantly enhancing its hardness.

3.Worm treatment: The worm gear of the gearbox undergoes nitriding treatment, which increases its hardness and improves wear resistance, thereby extending its service life.

4.Gear Treatment: The worm gear has been subjected to phosphate coating, enhancing its resistance to corrosion.

5.3D file: JIMAI is capable of providing 3D files of declutchable gearboxes in various capacities, allowing customers to verify whether the declutchable gearbox is compatible with their valve in terms of space.
