Hollow Plug Impact Reversing Sub

The Hollow Plug Impact Reversing Sub is a reversing circulating tool operated by inner pressure. The Hollow Plug Impact Reversing Sub is used in circulating work. Before cutting off the shear pins, the circulating port is always closed. When you need circulating work, you can charge pressure on the full bore to cut off the shear pins and open the circulating port. During running the tool, once the circulating port is opened, it can not be closed. The operating pressure is controlled by the amount of shear pins.

The tool is composed of valve body, shear pin plate seat, shear pin plate, shear pins and sealing rings. The shear pin plate seat is connected to the valve body through connecting thread and the shear pin plate is restricted in the shear pin plate seat through shear pins. It has simple construction and convenient maintenance.
