Emergency Shut-off Valve "Draw Bubble D+law Type"

Completely power-free! Weight self-closing and cylinder (spring-loaded) emergency shut-off valve.

The "Drawbar D+law type" is an emergency shut-off valve installed in the outflow pipes of water reservoirs or storage tanks, or in the branch connection pipes of pipelines. In the event of an earthquake or pipeline accident, it detects abnormalities without power and reliably performs an emergency shut-off. It functions effectively in preventing the outflow of stored water from reservoirs, particularly in water supply management during disasters. Additionally, changing the valve operation conditions based on "earthquake detection" and "flow velocity detection" (AND/OR) is easy, allowing for flexible adaptation to customer operational conditions. 【Features】 ■ Lock release mechanism ■ Web monitoring device ■ Compact height ■ Compatible with electric reset ■ Complete sealing of valve seat *For more details, please refer to the PDF document or feel free to contact us.
