【Case Study】Labor-saving for Opening and Closing Low-Pressure Manual Valves in Ethylene Production Line

【Case Study】Labor-saving for Opening and Closing Low-Pressure Manual Valves in Ethylene Production Line

By utilizing UH, it is possible to reduce labor and shorten time! Here are examples of Unihandler deliveries.

We would like to introduce a case study of the valve actuator "Uni-Handler" that our company handles. At a certain factory in the Kyushu region, there were many low-pressure manual valves (300A), which required considerable effort and time to operate. Although we competed with Bestork, the proximity of the valve positions allowed for the operation of 9 valves with a single drive unit, leading to the decision to adopt the UH operating method. In the modified mechanism, since the floor positions were different, we installed two drive units for each floor, allowing for the operation of 1 unit per 9 valves. As a result, by utilizing the UH, we achieved labor savings and time reduction, and discussions for implementation in similar facilities within the same factory have begun. [Case Study] - Delivery Location: Kyushu Region Factory - Delivered Product: Uni-Handler - Issues Before Modification: - Although it was a manual low-pressure valve, the large diameter required considerable effort and time to operate. - Benefits After Modification: - Labor savings and time reduction were achieved by utilizing the UH. *For more details, please refer to the PDF document or feel free to contact us.

[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.
