What are the characteristics of control valves

1. There are various types of control valves, and their applicable occasions are different, therefore, the type of control valve should be reasonably selected according to the requirements of the process production process.

2. Pneumatic control valves are divided into two types: air opening and air closing. The air-open control valve closes in the event of a fault and the air-closed control valve opens in the event of a fault. Some auxiliary equipment can be used to form a position retention valve or make the control valve self-locking, that is, the control valve can maintain the valve opening before the failure when it fails.

3. The way of air opening and gas closing can be realized by the combination of positive and negative actuator types and positive and negative body valves, and can also be realized by valve positioner when using valve positioner.

4. All kinds of control valves have different structures and have their own characteristics.
