The RMZ Hydraulic Wireline Annular Valve is designed to seal on a static cable under pressure and is recommended for “Safety while Logging” applications and for perforating with large guns.

Positioned above the drilling BOP, or a “Shooting Nipple”, it offers, once rigged up, a clean bore of 6” to 6 1/2” (depending on connection type) to run a tool through. The cable and rope
socket are connected to the head before passage through the main assembly.

The RMZ Hydraulic Wireline Annular Valve seals by squeezing a split rubber element which is wrapped around the wire. This element seals on the cable outer armour against well pressure, as well as wiping the wire free of fluid.

A hydraulic hand pump is required to operate the pack-off.
