Added a flexible structure to the repair joint. It prevents leakage and damage during an earthquake.
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.

basic information
【Other Features】 - It has the same 4° flexible angle as ductile earthquake-resistant pipes, absorbing the reaction force when colliding with the walls of the valve chamber, thereby reducing the load near the flange area. - It can flex up to 8° without leakage or disconnection, allowing for opening and closing. - The connection to T-shaped pipes uses flange joints. - It can be connected with bolts and nuts, just like conventional repair valves. - Despite having a flexible expansion and contraction structure, it achieves a compact inter-space dimension of 150mm. - It is compatible with shallow burial. *For more details, please refer to the PDF document or feel free to contact us.
