Note: According to different valve torque, different air pressure and different actual conditions, select the appropriate actuator size also changes its relevant
| Accessories selection | |
| The electromagnetic valve | Double-acting election two five-way, two-way single five-way, single electric double-control when ordering |
| Air treatment triplet | Regulated gas supply, filtration, cylinder lubrication |
| Limit switch | Remote feedback switch signal |
| Hand-operated institutions | Can be manually open, close the valve |
| Locator | Input analog signal (4-20mA or 0-10V), adjust the valve opening |
| Remarks | The above accessories are not standard accessories, such as the need to configure the order time, solenoid valves and limit switches are not explosion-proof and explosion-proof, if explosion-proof also indicate the level of explosion-proof |
