What are the types of electric control valves? What are the concepts of wind on and wind off? Is the difference between gas opening and wind opening the signals?
1. Electric control valves are driven by electric motors, and can be classified into electric butterfly valves, electric gate valves, etc., depending on the valve body type. 2. A gas-actuated valve refers to the operating principle of a pneumatic diaphragm control valve: it opens when there is air supply and closes when there is no air, and is thus called a gas-actuated valve ； Conversely, it closes when there is air and opens when there is no air; this is called a pneumatic control valve. 3. \"Air on\" and \"Wind on\" mean the same thing; they both refer to the air source for pneumatic diaphragm control valves, which is high-quality compressed air at a pressure of 0.4~0.6 MPa.
