The Rebco ROTX Equalizing Valve Sub-Assembly is designed specifically for use with ROTX and ROTXN Lock Mandrels and covers nipple seal bores from 1.500" to 4.562". Its function is identical to the ROTR Equalizing Valve Sub-Assembly: the sub allows pressure differentials to be safely equalized across the ROTX or ROTXN Lock Mandrel and its associated flow control device before any retrieval attempt from the Landing Nipple. The No-Go OD is machined slightly undersized relative to the nipple seal bore, ensuring the sub passes into the nipple without engaging the landing profile.

As with the ROTR series, each ROTX Equalizing Valve Sub-Assembly number directly corresponds to a specific ROTX or ROTXN Lock Mandrel assembly number at each nipple seal bore, and is available with or without an End Cap (the without-Cap version carries the "-1" suffix). All sizes are constructed from Norm Alloy per NACE MR-01-75, and a variety of additional materials are available to suit specific well conditions.

How to Order: Product Code 20. Specify nipple seal bore size, the ROTX or ROTXN Lock Mandrel assembly number to be equalized, End Cap or without-Cap configuration (suffix -1 for without Cap), and material. Full engineering data and Lock Mandrel cross-reference numbers are listed on Pages XV-17 and XV-18.
