The electromagnetic valve maintenance kit for Atlas Copco EWD330 electronic drainage valve mainly consists of the following components:
Typically, such kits are designed based on the structural characteristics of the electromagnetic valve, and include the following key components (subject to the original factory configuration):
Sealing elements: such as O-rings, sealing gaskets, etc., used to restore the sealing performance between the valve core and the valve body to prevent air leakage or water leakage.
Valve core and spring: as the core operating components of the electromagnetic valve, they may wear or lose elasticity over time. The kit usually includes replacement valve cores and springs.
Wiring-related accessories: may include wire sealing components or connection terminals (depending on the specific design).
Fasteners: such as special screws, clamps, etc., to ensure the stable assembly of all components after maintenance.
Function and purpose
The EWD330 electronic drainage valve is used to automatically discharge condensate water generated by equipment such as filters and air storage tanks in the compressed air system. The electromagnetic valve is the key component that controls the drainage action. By replacing aging or damaged components with this maintenance kit, the following can be achieved:
Restoring the sensitivity of the electromagnetic valve to ensure that the drainage valve opens and closes accurately according to the set program.
Solving leakage, frequent drainage or no drainage caused by sealing failure.
Extending the overall service life of the drainage valve and reducing the risk of system contamination caused by poor drainage (such as water entering downstream equipment and causing damage).
