The "EM Continuous Water Method" is a new technique that uses end mill cutting tools for continuous water construction. Conventional methods used a circular blade called a "hole saw," which could only drill pipes in a limited round shape. The "EM Continuous Water Method" allows for drilling by moving the end mill blade at a "point," enabling the cutting of pipes in free shapes and sizes. *We are currently offering a free comprehensive catalog that explains the "EM Continuous Water Valve Method"! Please download for more details. 【Features of the EM Continuous Water Valve Method "S-Gate"】 ■ Compact design! ■ Excellent water stopping performance! ■ Smooth repeated opening and closing operations! ■ Chips are forcibly discharged outside the pipe! *For more details, please contact us or download the catalog to view.

- It can be installed at any point on an existing pipe without interrupting the water flow. - After slightly leaving the pipe thickness, it is processed with a groove cutting, and then cut with a knife gate, ensuring that no cutting chips enter the pipe. - After installation, it can be operated repeatedly for opening and closing. - Since it is cut with a thin knife gate, the opening area is minimal, which minimizes the load on the pipe. - Because there is no drilling work involved, it can be easily installed in a short time. - Both the product and construction equipment are compact, allowing installation in tight spaces and indoor piping.

The "S-Bunki Valve" is a groundbreaking product that integrates the JWWA B 120 "Soft Seal Partition Valve for Water Supply" with a constant water branch pipe. It is also compatible with shallow burial, allowing for quick installation and reduced construction costs. High corrosion resistance and quality have been achieved through epoxy resin powder coating on both the inner and outer surfaces. Additionally, both ends of the branch are equipped with a full circumference packing, accommodating movement in both the pipe axis and pipe circumference directions. *For more details, please refer to the catalog or feel free to contact us.

It is a flangeless type that incorporates a unit with a PE insertion port into the "S-Bunki Valve." The unit connection part ensures a detachment prevention resistance of 3DkN, making it ideal for seismic piping. Additionally, like the "S-Bunki Valve," it guarantees reliable water tightness with a full circumference packing and corrosion resistance with internal and external epoxy powder coating. *For more details, please refer to the catalog or feel free to contact us.

By incorporating a ball-shaped flexible section (seismic isolation unit), we can relieve the stress on the branching section in shallow buried installations where ground displacement is likely to occur, thus safely protecting the pipeline. Additionally, similar to the "S-Bunki Valve," we ensure reliable water tightness with a full circumference packing and corrosion resistance with internal and external epoxy powder coating. *For more details, please refer to the catalog or feel free to contact us.

EF Bunkisoft integrates EF saddles and Hypolysoft (manufactured by Maezawa Kogyo Co., Ltd.) with existing polyethylene pipes using EF joint (electrofusion) to create a branch without stopping the water flow. The branching section becomes a unified structure with the pipeline, contributing to the seismic resistance of the pipeline. For more details, please download the catalog.

Integrate the EF saddle and ball valve with the existing pipe using EF joint (electrofusion) and perforate while maintaining a continuous water supply. Since the branching section becomes a unified structure of the pipeline, it contributes to the seismic resistance of the pipeline. *For more details, please refer to the catalog or feel free to contact us.

The "S-Gate EX" is a new model of the groundbreaking EM continuous water valve method "S-Gate," which perforates existing pipes in a groove shape using an end mill and inserts a soft seal valve body. The main body and construction equipment have become even more compact, making it possible to install continuous water valves in narrow spaces where installation was previously difficult. Furthermore, a simpler structure has been achieved, streamlining the construction process. Safe and speedy installation is now possible. 【Features】 ■ Can be installed at any desired location with continuous water ■ Smooth repeated opening and closing operations due to the soft seal valve body ■ Low torque operation possible with the soft seal valve body ■ All chips from the perforation are forcibly discharged outside the pipe ■ Valve body removal is possible *For more details, please refer to the catalog or feel free to contact us.

A simple and smart design that consolidates the experience and know-how gained from the EM continuous water valve method "S-Gate." By drilling the existing pipe in a groove shape and inserting a soft seal valve body, water can be stopped with a torque similar to hand-tightening, allowing for smooth repeated opening and closing operations. The compact main body, which emphasizes functionality, and the small drilling machine designed for 100V power supply minimize the load on the pipe, enabling safe and speedy construction.

The "S-Gate" series of EM continuous water valve construction methods has introduced the S-Gate VP for PVC pipes. Since it has a built-in working partition valve in the main body, the valve body can be easily removed without using special equipment. The perforating machine is compatible with both 12V and 100V power sources. Both the main body and construction equipment are compact, minimizing the burden on the pipes.
