Three types of actuators for gas gate valve

For gas gate valve actuators, currently there are three main sources of power to choose from: electric, pneumatic and hydraulic. The details are as follows:

1. Electric actuator

The motor should usually be of fire-proof and explosion-proof structure, and the cable should be of flame-retardant or fire-resistant type. Considering the influence of motor insulation materials, it is not suitable to use in high-humidity places.

2. Pneumatic actuator

Sufficient power supply and good cylinder and piston coordination and lubrication are the keys to the normal operation of pneumatic actuators. Otherwise, lax shutdown and jams will occur.

3. Hydraulic actuator

In addition to requiring the hydraulic fluid to be non-corrosive and freeze-free in winter, it is not restricted by more factors, the system is simple, and it has a trend of popularization and application.

The above is the introduction of the relevant content of the three actuators of the gas gate valve, I hope it will be helpful to everyone.
