1. Design and Functions

1-1. Technical Features

① Turn the main power supply ON/OFF to open/close the valve.

•

Unlike conventional electric valve actuators, only two wirings are required for the

ON-OFF operation.

② There are no problems of water hammers.

•

Since the operation speed is not too fast unlike solenoid valves, there are no

problems of water hammers even if the fluid is liquid.

③ Manual operation

•

It is easy to operate manually.

④ Manual lock mechanism

•

Since it is equipped with the manual lock mechanism, it is possible to hold the valve

in the open status even if the power supply is turned off.
