• Cement Valve


    The Cement Valve is a check valve designed to support a column of fluid, until such time as 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 sees the selected cross sectional area and begins to compress the disc springs.


    The disc springs are compressed, holding the piston nose on seat, preventing the from travelling through the tool. Pressure acting on the piston


    When the pressure is increased the force acting on the piston the fluid is allowed to bypass the piston seat and travel down the tool.


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


    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.




    • Works in under balanced situations
    • Suitable for most fluid applications
    • Multiple operating delivery pressure configuration
    • Precision calibrated valve opening pressure against pre-determined B.H.P.
