Electric valve storage box SBK-25K
The drainage function during testing keeps the sprinkler piping dry without filling it with water! Due to the electric three-way valve, connecting it to the water supply prevents stagnant water!
It operates based on signals from the electric valve control panel SBK-25Z of the specific facility water supply connection type sprinkler system (dry type).

Detailed information
-
[Normal valve position and water flow] Water enters from A and flows to the right (primary side) via B (electric three-way valve). When a signal is received from the control panel (during a fire), B (electric three-way valve) operates and changes the water flow to the left (secondary side), filling the fire extinguishing pipe. *Please set the handle at A vertically, the handle at C vertically, and the handle at D vertically.
-
[Position of the valve and water flow during testing] If you are testing whether B (electric three-way valve) operates normally without filling the fire protection pipe, please position the handle C horizontally. *After the test is completed, please return the handle C to the vertical position.
-
[Position of the valve and water flow during drainage] When draining the water filled in the fire protection pipe, please turn the handle C to the right at a 45° angle to drain the water. After the drainage is complete, please return the handle C to the vertical position.
-
[Position of the valve and water flow in an emergency] If for some reason B (electric three-way valve) does not operate, you can fill the fire extinguishing pipe by turning the handle D horizontally. *Note: D should never be opened (handle horizontal) during normal conditions.
