Super compact body designed for tight spaces! The definitive version of a continuous water valve that brings together all the know-how!

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.

Since our establishment in 1970, we have been a manufacturer of special fittings dedicated to protecting lifelines, introducing numerous innovative products to the market. The ductile iron ball-shaped flexible expansion joint "Flexibender," released in 1980, demonstrated its seismic performance during the Great Hanshin-Awaji Earthquake and the Great East Japan Earthquake. The EM continuous water supply method "S-Gate" series, launched in 1999, has steadily achieved results in various countries around the world, including the United States and South Korea. We are committed to product development with free thinking, unconstrained by conventional wisdom, and contributing to the safety of lifelines.
