The Rebco ROTPR Equalizing Prong and Valve Sub-Assembly is a more advanced equalizing device that, when attached to a ROTR or ROTRN Lock Mandrel Assembly, converts the lock mandrel into a full Plug Choke with an integrated equalizing device, capable of holding pressure differentials from both above and below. This is the critical distinction from the standard ROTR Equalizing Valve Sub-Assembly: where the ROTR equalizing sub simply bleeds off pressure before retrieval, the ROTPR creates a bidirectional pressure-holding plug choke that remains set in the nipple and actively manages pressure in both directions. The ROTPR covers nipple seal bores from 1.781" through 5.963", making it the broadest-range equalizing sub-assembly in the Rebco line.

The ROTPR incorporates a Prong that extends below the valve assembly; the Prong Fishing Neck provides the engagement point for the Prong Running and Pulling Tool, which is used to set and retrieve the prong independently of the lock mandrel. The V-Packing OD varies by size, from .818" at the smallest seal bore up to 2.313" at the largest, and Prong lengths range from 22.4" for the smallest sizes through 52.62" for the 5.875" seal bore. The Prong Running and Pulling Tool also varies by size and must be specified correctly when ordering. All sizes are constructed from Norm Alloy, certified for H2S service per NACE MR-01-75.

How to Order: Product Code 24. Specify nipple seal bore size, the ROTR or ROTRN Lock Mandrel assembly number to be used with, V-Packing OD, Prong Running and Pulling Tool number for the applicable size, material, and service conditions. Full engineering data, including prong lengths and Prong Running and Pulling Tool numbers, are listed in the engineering data tables on Pages XV-13 through XV-16.
