How to operate the valves?
Valve can be operated manually or automatically using an actuator.
Manual operation type
There are three main methods of manual operation.
This is a typical manual operation method for gated valve and globe valve.
(Picture shows a stainless-steel gate valve.)
This is a typical manual operating method for the ball valve.
(The picture shows Brass ball valve.)
It is set to butterfly valve and ball valve. There are also hammer blow type and chain wheel type.
(Aluminum butterfly valve)
Automatic operation type
There are two types of automatic operation, depending on the driving source for driving the actuator.
An actuator that uses electricity (alternating current or direct current) as a driving source.
(EXH type in the picture)
Actuator driven by compressed air for instrumentation.
(FAS type in the picture)
The use of oil as the driving source enables a large operating force to be obtained, and the actuator can be miniaturized
Types of actuator and Typical valve
|Pneumatic type||Cylinder type||Gate, glove, butterfly, ball|

|Manual||Gate, glove, butterfly, ball|
We offer a lineup of actuators developed in-house for driving ball valve and butterfly valve.
In addition to our proprietary actuators, we have a wide range of pneumatic and pneumatic actuators.
