The "Seismic Repair Valve" is a water supply repair valve that integrates a flexible structure on the main pipe side of a ball-shaped repair valve for seismic resistance. Under normal conditions, it maintains its installed state, but when excessive pull-out forces or bending loads, such as those from an earthquake, are applied, the initial holding state is released, allowing for flexible movement. Even after an earthquake occurs, it ensures operational functionality and water-stopping capability as a repair valve, enabling reliable firefighting activities and emergency restoration. 【Features】 ■ Adds a flexible structure to the repair valve ■ Installation is the same as conventional repair valves ■ Compatible with shallow burial ■ Maintains excellent operational functionality and water-stopping capability through tests simulating main shocks and aftershocks ■ Proven performance to withstand seismic waves of intensity 7 *For more details, please refer to the PDF document or feel free to contact us.

The "NS Butterfly Valve with Filling Function" is a water supply butterfly valve that incorporates a filling function valve body to improve the workability of initial water filling in the seismic-resistant NS butterfly valve. It excels in control at small openings, allowing for safe water filling operations. The newly developed rubber valve seat structure demonstrates excellent sealing performance. The rubber valve seat can also be replaced. Additionally, the valve body structure has been modified to include the filling function while maintaining the operability of the center cap type NS butterfly valve. The operating torque during filling is low, making opening and closing operations easy. 【Features】 ■ Filling function included ■ Excellent sealing performance ■ Replaceable rubber valve seat ■ Easy opening and closing operation ■ Simple structure that reduces costs ■ The opening degree gauge features a scale with a filling function *For more details, please refer to the PDF document or feel free to contact us.

The "Multi Gasket" is a product with a structure that features a stainless steel core lined with rubber, and has annular protrusions and grooves on the gasket surface. During an earthquake, there may be a temporary increase in pressure that directly impacts the flange area, potentially causing water leaks. Furthermore, if the discovery of the leak is delayed and the gasket shape becomes deformed, tightening the bolts and nuts will not stop the leak. This product was developed to solve these issues. Please make use of it to enhance seismic resistance for your stockpiles. 【Features】 ■ Maintains high water-stopping capability ■ Suppresses deformation even during pipe bending, preventing protrusion and damage ■ Compatible with both GF and RF ■ Easy centering (GF type) ■ Compatible with all flanges of 7.5K, 10K, and 16K *For more details, please refer to the PDF materials or feel free to contact us.

The "Multi Gasket" is a versatile core-insert gasket that can accommodate any flange with just one piece. Thanks to its unique bolt hole shape, it can be used with flanges rated at 7.5K, 10K, and 16K. It is also compatible with all flange connections, including GF type-RF type, RF type-RF type, and GF type-GF type. Incorporating a stainless steel core, it prevents the gasket from popping out or being damaged due to piping bends or high pressure in the pipeline caused by disasters. 【Features】 ■ Compatible with any flange due to its unique bolt hole shape ■ Easy centering ■ Contains a stainless steel core ■ Maintains high water-stopping ability *For more details, please refer to the PDF document or feel free to contact us.

"Change Soft" is a product for connecting different types of pipes using only soft seal partition valves, allowing for changes in pipe types. It can be used at the switching points between polyethylene pipes (PE pipes) and PVC pipes (VP pipes), resulting in fewer connection points. Standard products include handle-operated types and those with opening degree gauges. We offer "VP×PE mechanical type" and "VP×PE insertion type." 【Features】 - The connection of polyethylene pipes meets the detachment prevention performance of POLITEC standards. - Fewer pipe connection points. - The mechanical joint side can be reconnected simply by replacing the parts with new ones. - Can be used in narrow spaces and other areas. - Ensures pull-out prevention and water tightness, among other features. *For more details, please refer to the PDF document or feel free to contact us.

It is made of all stainless steel with excellent weather resistance and is unpainted. It combines corrosion resistance and durability, and the valve body uses chlorine-resistant rubber (EPDM), ensuring peace of mind for long-term use. 【Features】 ■ The valve body uses heat-resistant fluorine rubber, making it suitable for a wide range of applications. ■ The integrated molding with rubber prevents the rubber from peeling off. ■ By significantly reducing the amount of rubber used, it has less impact on fluids and is environmentally friendly. ■ The straight shape of the valve box bottom allows for smooth fluid flow. ■ It maintains high sealing performance even in the presence of foreign substances, as it seals with rubber compression. *For more details, please request documentation or view the PDF data available for download.
