CSL Model.-

This product has the same application as the SL Model, but has an additional device to equalize the tubing and casing in order to open the sleeve. This device has been designed to diminish the pressure differential, between pressure of tubing and the annular space, in order to optimize the operations of opening and closing.

SL Model .- The Sliding Sleeve type “SL” casing is a sub surface valve specifically designed for down hole completions. It is used to hook the tubing into the annular space for wells with varying sand production. The jet pump can also be fitted into it for testing or production. It is very easy to open and close with slick line equipment and a shifting tool. It is manufactured with measurements ranking from 2-3/8”, 2-7/8”, 3-1/2” and 4-1/2”, with threads as requested by the client. The material used for this tool is 4340 steel, the closing sleeves come from Canada. These tools are manufactured under strict quality control and are subject to pressure testing before entering our warehouses.
