Cross-over valves are essential components in fluid control systems, designed to divert or switch the flow direction between multiple pipelines. These valves are widely used in industrial automation, hydraulic systems, and pneumatic applications, ensuring efficient flow management. Common types include 3-way and 4-way crossover valves, which enable seamless switching between different flow paths. Key features include durable construction (often from brass, stainless steel, or engineered plastics), high-pressure resistance, and compatibility with various fluids (air, water, oils). Examples of products in this category include manual crossover valves, solenoid-operated crossover valves, and motorized crossover valves, catering to diverse automation and MRO needs.
