The 4 way ball control valve features four ports around its chamber and a centrally positioned cock plug with two passages connecting adjacent ports. This design allows each port to have two flow positions, providing efficient control over fluid direction. In the closed position, both the inlet and exhaust ports remain open. These valves are particularly effective in double-acting cylinders, as they supply pressure to one side while venting the opposite side to the atmosphere. 4-way ball control valves are cost-effective solutions for flow regulation, throttling, and on-off operation across various applications.
