[Case Study] Labor-saving in Manual Steam Well Valve Operation and Reduction of Scale Adhesion

[Case Study] Labor-saving in Manual Steam Well Valve Operation and Reduction of Scale Adhesion

Reduction of opening and closing time, and labor saving! Introducing case studies of Uni-Handlers.

We would like to introduce a case study of the valve actuator "Uni-Handler" that we handle. At a certain power and geothermal power plant, the opening and closing of the steam well valve (manual type) was extremely difficult due to scale buildup inside the piping, and while it was performed during regular maintenance, it required significant labor. By introducing the "Uni-Handler" in the modified mechanism, we were able to reduce the opening and closing time and achieve a reduction in labor. Additionally, the conventional drive body, flexible shaft, and attachments were transported separately, but by newly fabricating a transport cart for the equipment, simultaneous transportation of the necessary equipment became possible, improving work efficiency. [Case Study] ■ Delivery Location: Power and Geothermal Power Plant ■ Delivered Product: Uni-Handler ■ Issues Before Modification: - The opening and closing operations took a considerable amount of time, leading to a decrease in opening and closing frequency and promoting scale growth. ■ Benefits After Modification: - Reduction in opening and closing time (reduction in labor) *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Remote operation of manual valves at safety work points.

[Case Study] Remote operation of manual valves at safety work points.

Connecting a flexible shaft to the target valve! Introducing a case study of unihandlers.

We would like to introduce a case study of the valve actuator "Uni-Handler" that we handle. At a certain power generation plant, valves with high opening and closing frequency were automated to reduce labor, but valves with low frequency were still manual, requiring a lot of effort and time for their operation. In the modified mechanism, by connecting an attachment and a flexible shaft to the target valve, remote operation (at a safe point) became possible, significantly reducing both effort and time. [Case Study] - Delivery Location: Power Generation Plant - Delivered Product: Uni-Handler - Issues Before Modification: - The position of the target valve was in a hazardous area, making opening and closing very troublesome and labor-intensive. - Advantages After Modification: - By connecting a flexible shaft to the target valve, it became possible to operate it from a work point, significantly reducing effort and time. *For more details, please refer to the PDF document or feel free to contact us.

Air motor type valve actuator "Bestork" series

Air motor type valve actuator "Bestork" series

Air motor type valve actuator "Bestork" series

Air Motor Type Valve Opening and Closing Device "Bestork" 【Features】 ○ Compact and lightweight, high output The air motor uses compressed air to deliver powerful performance. Its power is particularly strong in explosion-proof areas. ○ No major modifications required Installation involves attaching a mounting bracket to the existing valve, setting a boss in place of the handle, and simply bolting the main unit. ○ No restrictions on valves Automation is possible for any device that is operated by a handle, not just valves. ○ Flexible installation direction It can be installed in any direction: down, sideways, or vertically. ○ No limitations on valve size It accommodates valves of all sizes, whether small or large. ○ Control valve Proportional control is possible by using an electric positioner. ○ Smooth opening and closing control With the closing torque limiter, the torque difference during opening and closing is managed, and at the start of opening, an automatic gear ratio switch ensures that 1.5 times the torque is effectively applied. ● For more details, please download the catalog or contact us.

[Case Study] Labor-saving of main steam connection valves between boilers

[Case Study] Labor-saving of main steam connection valves between boilers

The drive method adopts air drive! Introducing examples of unhandlers delivered.

We would like to introduce a case study of the valve actuator "Uni-Handler" that we handle. At a certain factory in the Chubu region, despite being a high-pressure valve, it was manual, requiring considerable effort and time for opening and closing the valve. Additionally, the valve's location was not suitable for operation, resulting in a poor working environment. Therefore, in the modified mechanism, since each valve position was nearby, a single drive unit could be used, leading to cost merits, and the UH method was chosen. As a result, by utilizing the UH, labor-saving and time reduction were achieved, and there was interest in updating and maintaining the existing UH within the same factory. 【Case Study】 ■ Delivery Location: Factory in the Chubu Region ■ Delivered Product: Uni-Handler ■ Issues Before Modification: - Required effort and time for opening and closing due to manual high-pressure valves. ■ Advantages After Modification: - Achieved labor-saving and time reduction by utilizing the UH. *For more details, please refer to the PDF document or feel free to contact us.
