Globe valves (spherical valves, stop valves) inherently have a large pressure loss due to their structure, and it is unavoidable that the valves themselves are large and heavy. Flowtech's ball valves, the "BKH series" and "MKHP series," have no pressure loss because they are full bore (with some reduced bore options). Additionally, due to their simple structure, which is a characteristic of ball valves, they are smaller in size compared to globe valves (spherical valves, stop valves) of the same diameter. As the size of the valve decreases, it is possible to reduce the weight of the valve body. By making the valve smaller and lighter, the equipment that incorporates the valve can also be downsized and lightened. This directly affects transportation costs when exporting equipment overseas, so there are advantages to switching from globe valves to ball valves. If you are using globe valves for ON-OFF applications, why not consider switching to ball valves? Features: - No pressure loss due to full bore - Smaller and lighter compared to globe valves due to simple structure - Available in sizes from 1/4 to 2 inches, with maximum operating pressure up to 50 MPa (depending on size) - In stock for quick delivery options

While the device was operating, the valve was accidentally opened or closed. The device was operated before opening or closing the valve. Have there been any accidents due to operational mistakes on site? We offer various options such as explosion-proof limit switches and solenoid valves for malfunction prevention and interlock mechanisms. Examples of safety measures: - Use limit switches to monitor the open/close status of the valve and add an interlock mechanism to the control panel. - Prevent valve movement unless a two-step operation is performed using a plunger lock, thereby avoiding operational mistakes. - Attach a padlock to ensure that only the key holder can open or close the valve. - Lock the padlock during maintenance to prevent valve operation. - Use color markings on handles to identify parallel piping lines by their purpose. *For more details, please refer to the PDF document or feel free to contact us.
