HOW DO DIRECTIONAL CONTROL VALVES WORK?

DCVs play a crucial role in hydraulic circuits by enabling bi-directional motion for hydraulic actuators and offering advantages to any device equipped with a motor. Their versatility lies in their ability to be precisely controlled to assume different positions, making them suitable for a wide range of functions.

          Directional control valves serve the purpose of maintaining fluid in a standby state, effectively halting its flow within the system until it is required to initiate and execute its designated task. While these valves offer significant advantages, the intricacies of their mechanical components can occasionally give rise to complications, including potential contamination issues.

          To circumvent problems or failures associated with Directional Control Valves (DCVs), the most effective approach is to prevent contamination within the system. Ensuring that the oil remains clean, maintains a suitable temperature, and stays free from moisture intrusion (thus averting water contamination) will serve as a robust preventive measure against the majority of DCV failures. This, in turn, will enhance the durability of DCVs within the hydraulic system.
