Description

The cement valve is a check valve designed to support a column of fluid until an increase in pressure is applied to the column from above. Once the increased pressure is seen at the valve, it will open, and the column of fluid will be allowed to flow through the valve. By reducing pressure to the column of fluid to its original level, the valve will close, and the fluid will cease to flow.

As pressure is applied to the column of fluid, it identifies the selected cross-sectional area and begins to compress the disc springs. The disc springs are compressed, holding the piston nose on seat and preventing it from traveling through the tool. When the pressure is increased, the fluid bypasses the piston seat and travels down the tool.

The cement valve can be reconfigured to operate at different pressures in a range from 500 psi.

The cement valve was originally developed as a control valve capable of accurately delivering cement during coiled tubing cementing operations. The same tool can also be used to deliver any fluid downhole using the same principle.

When ordering cement valves, please specify size and thread connection.
