Emergency shutoff valve EIT-3DN type electromagnetic emergency shutoff valve
The operation is valve closing when energized. Restoration is a safer recovery method because the shutoff valve is opened manually after operating the seismic sensor reset switch on the control panel.
Generally, it is attached to the outlet of a water receiving tank or elevated water tank, and in an emergency, the pipeline and the water tank are blocked by a signal from the control panel to secure water in the water tank.
It complies with the "water tank external type emergency shutoff valve" according to the "Comprehensive Seismic Planning Standards for Government Facilities".
- Where to use
- Water tankHigh water tankWater supply branch pipe
Major features
- An electromagnetic emergency shutoff valve compatible with the emergency shutoff system for water tanks.
- The main body is made of stainless steel or bronze, and no red water is generated.
- In combination with the CB type control panel, an emergency shutoff system for the water tank can be constructed.
