[Issues that can be resolved] Want to install an emergency shut-off valve but cannot cut off the water supply.

The emergency shut-off valve can be installed in the outflow pipe inside the water distribution tank, allowing for installation work without cutting off the water supply!

In the case of a single-chamber distribution reservoir, if you try to install an emergency shut-off valve outside the reservoir, it will need to be placed on the main distribution pipe. If you want to carry out continuous water work to avoid water outages, space will be required to install a bypass pipeline, and if space cannot be secured, the emergency shut-off valve cannot be installed. Therefore, if the valve of the emergency shut-off valve is installed on the outflow pipe inside the distribution reservoir, construction work can be carried out through diving operations. Since work underwater will only involve flange connection work, installation can be carried out without shutting off the water. [Issues] - There are cases where a bypass pipeline cannot be installed, resulting in an inability to shut off the water. - If space cannot be secured, the emergency shut-off valve cannot be installed. - Even if space is secured, new construction costs will arise. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Mitigating the Risk of Drinking Water Loss in a Water Distribution Reservoir Where Installing an Emergency Shutoff Valve is Difficult

[Case Study] Mitigating the Risk of Drinking Water Loss in a Water Distribution Reservoir Where Installing an Emergency Shutoff Valve is Difficult

Introduction of a case that cleared the issue of installation space for emergency shut-off valves and eliminated the risk of drinking water loss.

In Nakatsugawa City, there was no space around the Okute water reservoir in the Ochiai area of the water supply system, and acquiring nearby land was also difficult, which led to a deadlock in the installation of emergency shut-off valves. Therefore, an underwater emergency shut-off valve "NCS-A-150" was installed in one of the two water reservoirs on the outflow pipe inside the reservoir. By installing the valve controller at the top of the reservoir, we were able to clear the issue of installation space without acquiring land. As a result, we were able to eliminate the risk of drinking water loss due to pipeline damage caused by disasters such as earthquakes. 【Overview】 ■ Location: Nakatsugawa City, Gifu Prefecture ■ Implementation Period: Fiscal Year 2017 ■ Construction Summary - Installation of underwater emergency shut-off valve NCS-A-150 in a two-tank reinforced concrete water reservoir with a capacity of 300m3 in Nakatsugawa City water supply system. *For more details, please refer to the PDF document or feel free to contact us.

Proposal for BCP-compliant emergency shut-off valve system

Proposal for BCP-compliant emergency shut-off valve system

Is the water okay during a disaster? An emergency shut-off valve system that can operate with UPS power even during a power outage, in line with BCP measures.

At Kankogyo Co., Ltd., we are proposing an emergency shut-off valve system that is compliant with BCP (Business Continuity Plan). In areas where major earthquakes have occurred, there have been issues such as: "During disasters, muddy water entered the water tank, making it unusable for drinking." "In one building, people who did not reside there used the restroom, quickly depleting the water in the receiving tank." Our system closes the emergency shut-off valve upon activation of the seismic sensor, blocking mud and muddy water, and thoroughly flushes out mud and foreign objects through the strainer. 【Features】 - Installation of an emergency shut-off valve on the primary side of the water tank to prevent mud inflow. - Installation of a strainer on the primary side of the emergency shut-off valve for flushing capability. - Operable even during power outages due to UPS power supply. - Prevention of foreign object entrapment in the constant water level valve. - Protects drinking water while securing utility water. *For more details, please refer to the PDF document or feel free to contact us.

[Issues that can be resolved] Unable to secure space for the installation of emergency shut-off valves.

[Issues that can be resolved] Unable to secure space for the installation of emergency shut-off valves.

The emergency shut-off valve is installed on the outflow pipe inside the water distribution reservoir, eliminating the need for additional installation space.

To install an emergency shut-off valve, it is necessary to create a bypass pipeline outside the water distribution reservoir and build a pit for the installation. In some locations, it may not be possible to secure that space, forcing the abandonment of the installation of the emergency shut-off valve. As a result, the risk of drinking water leakage due to damage to the main water distribution pipe caused by earthquakes and other disasters remains unresolved. Therefore, by installing the valve of the emergency shut-off valve in the outflow pipe inside the water distribution reservoir and connecting a valve rod that rises from the valve to the drive unit installed at the top of the reservoir, we can secure the installation space. There will be no need to secure new installation space outside the water distribution reservoir. [Issue] ■ In some locations, there may be cases where the installation of the emergency shut-off valve is abandoned. *For more details, please refer to the PDF document or feel free to contact us.

Emergency Shut-off Valve "EM/EMV Series"

Emergency Shut-off Valve "EM/EMV Series"

No electrical operation is necessary! Introducing an emergency shut-off valve that operates reliably even during a power outage.

The "EM/EMV Series" is a valve that automatically closes the internal flow path due to the pressure difference generated by the flow velocity between the A and B ports when a sudden flow exceeding the set flow rate from the A port to the B port occurs due to a failure such as a pipe break on the B port line, instantly cutting off the flow of hydraulic oil from the A port. There are two types available: "EM," which only shuts off the installed piping, and "EMV," which is installed on multiple pipes and shuts off other pipes in conjunction when one of them operates. Additionally, we also offer the "EMS/EML/EMVL Series" with sensors. 【Features】 ■ Instantly cuts off the flow of hydraulic oil from the A port ■ Does not require electrical operation and operates reliably even during power outages *For more details, please refer to the PDF materials or feel free to contact us.
