Introduction：

The muti circulation switch valve is a tool that utilizes hydraulic pressure to switch flow paths, completing a single switch by starting and stopping the pump. This tool can be integrated into coiled tubing milling operations. After drilling out a certain number of bridge plugs, it can switch the flow path to the annular outlet, enabling high-flow-rate well flushing and flowback operations. Additionally, the tool can function as a control valve. By adjusting the size of the annular nozzle, it can alter the pressure within the tool string to control other downhole tools.

Features and Benefits：

★ Adjustable activation pressure

★ Adjustable annular nozzle

★ Shorter length

★ Unlimited switching capability
