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.
-
Handle type
This is a typical manual operation method for gated valve and globe valve.
(Picture shows a stainless-steel gate valve.) -
Lever type
This is a typical manual operating method for the ball valve.
(The picture shows Brass ball valve.) -
Gear type
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.
-
Electric type
An actuator that uses electricity (alternating current or direct current) as a driving source.
(EXH type in the picture) -
Pneumatic type
Actuator driven by compressed air for instrumentation.
(FAS type in the picture) -
Hydraulic type
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
| Actuator | Typical valve | |
|---|---|---|
| Pneumatic type | Cylinder type | Gate, glove, butterfly, ball |
| Pneumatic type | Air motor type | Gate, glove |
| Electric type | Multi-turn | Gate, glove |
| Electric type | Part-turn system | Ball, butterfly |
| 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.
