Check valves are critical valves used in hydraulic systems to ensure that flow only moves in the desired direction and to prevent reverse flow. They are generally divided into two main categories: single-acting and double-acting. Single-acting check valves allow flow in only one direction with a simple design, while double-acting check valves offer the ability to control flow in both directions with pilot pressure or an external control. In addition, pilotless check valves operate only in the direction of flow, while piloted check valves provide precise control by releasing flow when a certain pressure is reached. Check valves, offered with various connection types such as DIN2353, SAE, surface mounting or bolted connection, offer solutions suitable for different system needs. Thanks to their compact design and durable structure, they have a wide range of uses from industrial applications to mobile hydraulic systems.
