Back Pressure Valve Pressure Balanced Manually Operated Lubricator


The CAMTOP Oil Pressure Balanced Manually Operated (PBMO) Lubricator can be customized for most stroke lengths required up to around 20 FT. There is no welding used in our design and the lubricator can accommodate either a 1-1/8″ polished rod or a 1-1/4″ polished rod by simply changing the rod and packings. The packings used are spring energized and do not require the use of a packing gland nut wrench.


BPV and TWCV Installation and Removal


Back Pressure Valve Pressure Balanced Manually Operated Lubricator

Type H Back Pressure Valve (BPV) is a one way check valve, also known as a non return valve or NRV, which is used to safely seal tubing during installation of Christmas Trees, removal of the Blowout Preventer(BOP), and to prevent backflow of fluid into the tubing. BPV can substantially reduce downtime and operating costs by allowing for repairs without killing the well.

It is sometimes necessary to isolate the Blowout Preventer stack or the Production Tree from pressure in the tubing. The “H” Back Pressure Valve (BPV) is designed to block the pressure coming upstream from the well during the removal of the BOP and during installation of, or repairs to the production tree. The lubricator features allow the BPV to be used as a well-intervention valve or as a lubricator valve.

The Back Pressure Valve and Valve Removal (VRL) Lubricators are available for wellhead servicing in 2M, 3M, 5M, 10M, and 15M pressure ratings. These are offered with various interface connections to accommodate standard and custom stroke lengths. All associated running tools, BPV, Two Way Check, adapters, VR Plugs and tooling are available for API 6A and OEM equipment.

Aside from back pressure valve lubricators, we also manufacture and provide other wellhead assembly service tools such as Wear Bushing, Wear Bushing R/R Tool and Test Plug Combination Tool, test flanges etc.
