1. Ensure the quality of the solenoid valve

The selection of solenoid valves must undergo strict calculations; The type, caliber, and various performance must meet the requirements; The materials for various components of solenoid valves must be strictly selected, with sufficient strength and stiffness, and must pass pressure tests, air tightness tests, and other tests in accordance with national standards. The manufacturing technology and testing methods of the manufacturer must comply with the standards and be approved by the competent department. It is strictly prohibited for small factories without production conditions to carry out production.

2. Ensure reliable operability

This not only refers to the manufacturing quality of the solenoid valve itself, but also includes the training and improvement of the quality of the operators. To prevent misoperation, process personnel must pay attention to the precautions indicated on the nameplate. According to China's standards for pneumatic solenoid valves. The nameplate of the pneumatic actuator should at least indicate the manufacturer's name, product model, rated flow coefficient, design tag number, product number, and manufacturing year and month. Arrows indicating the direction of medium flow, DN values, and PN letters and values should be cast or punched out on the valve body. Important valves should have sufficient accessories, such as positioners, limit switches, etc. There should be sufficient installation and operation space, adequate lighting, and strict operating procedures.
