Our latest exploded view reveals the key components of the 4V solenoid valve, including the coil, armature, valve body, and seals, working together to deliver efficient and reliable fluid control. Every detail reflects OLK's commitment to quality and innovative engineering.

In the pneumatic system different period ,it will happen many faults.We can sort out three types period:Initial faults,sudden faults and aging faults.

Pressure Center: Refers to the pressure applied at the solenoid valve’s inlet. Exhaust Center: Describes a state where fluid can be exhausted from one or more ports in the middle position. Closed Center: Describes a state where all ports are sealed, preventing fluid flow in the middle position.

In industries ranging from water treatment to oil and gas, the ability to precisely control fluid flow is critical for safety, efficiency, and cost management. Among the many control devices available, the manual valve remains a fundamental component due to its reliability, simplicity, and cost-effectiveness. Despite the rise of automation, manual valves continue to play an indispensable role in countless systems worldwide. This article explores their functions, types, benefits, and how to select the right one for your needs, helping you overcome common challenges such as leakage, inefficiency, and system failure.

Our pneumatic solenoid valves, mechanical valves, and foot valves etc. continue to provide stable and reliable performance in your production and automation systems. Your choice helps us grow and innovate.

When compressed air is used as an industrial power source or process gas, it inevitably contains a variety of harmful impurities, which mainly come from the atmosphere itself and the working process of the air compressor.
