The Atos solenoid valve features a new type of electro-hydraulic integrated design, with a streamlined structure and excellent performance.

2. Highly reliable wet electromagnets also have explosion-proof, Atos solenoid valve intrinsic safety, and armored types, which can be used in maritime or military fields.

3. All seals are static seals, and all moving parts are protected and lubricated by hydraulic oil.

The optional switching control device of Atos solenoid valve ensures smooth and reliable direction change.

5. Plastic encapsulated coils are easy to replace.

6. Various electrical/electronic connectors depend on the application situation and the electrical installation interface.

7. The Atos solenoid valve ensures a low pressure drop by casting oil channels.

The interchangeable valve cores of Atos solenoid valves facilitate the composition of different valve core functions.

The Atos explosion-proof valve is usually installed directly on the oil cylinder. When the pipeline entering the explosion-proof valve bursts, the explosion-proof valve immediately seals the oil in the oil cylinder to prevent accidents from occurring. It flows normally in the forward direction, and when flowing in the reverse direction, the pressure difference between the two ends of the explosion-proof valve cannot exceed the spring force inside the explosion-proof valve, otherwise it cannot flow in the reverse direction (the same principle as pipeline explosion).
