Venn EIM-7N Mechanical Emergency Shut-Off Valve (Butterfly Type)

Manufacturer: Venn Co., Ltd.
Model: EIM-7N

Features

As a mechanical shut-off valve, there is no need for power outage countermeasures (emergency power supply equipment) or electrical equipment work, excluding switch wiring for operation.
It can also use in mountainous areas without a power supply.
Since the shock detector and shut-off valve install separately, the shock sensor mounts on a solid structure or sturdy wall, separate from the piping system, preventing malfunctions caused by pipe vibrations.
Due to its small size and lightweight design, it can easily install in existing aquariums.
