We have updated the English version catalog of the "Two-Stage Open/Close Rotary Air Operated Drive Unit, Two-Stage Open/Close Ball Valve," handled by Japan Diavalve Co., Ltd. This product features a mechanism that allows for mechanical two-step operation in the opening and closing of the valve by installing a sub-cylinder to our standard rotary air operated drive unit (90-degree rotation, Scotch yoke type, W piston). It enables the flow of a fixed amount of fluid through staged operation and has a proven track record for capacity control in quantitative shipping lines and water hammer prevention. Please download the catalog and take a look. 【Product Features】 ■ Installation of a sub-cylinder to our standard rotary air operated drive unit ■ Mechanism for mechanical two-step operation in the opening and closing of the valve ■ Ability to flow a fixed amount of fluid through staged operation ■ Proven track record for capacity control in quantitative shipping lines and water hammer prevention *For more details, please refer to the PDF document or feel free to contact us. *You can download the English version catalog.
