CAMTOP Valve Puller | Model F & G Series | For Float Valve Removal from Subs and Drill Collars

CAMTOP Valve Puller — Model F & G Series for Float Valve Retrieval

The CAMTOP Valve Puller is a specialized downhole fishing tool designed to retrieve stuck, damaged, or tight float valves and plug-retention assemblies from drill collars, tubing subs, and float equipment. Available in two purpose-built series — Model F (single-purpose) and Model G (dual-purpose) — CAMTOP valve pullers provide reliable valve extraction during tripping operations, workover interventions, and BOP stack assembly.

Manufactured from high-strength alloy steel with heat-treated engagement catches, every CAMTOP valve puller is engineered to engage the bottom of the float valve with positive locking action, rotate 90° to seat the catch, and then lift the valve out using the integrated bumper stop. The Model G series adds the ability to remove and install seal-retaining rings when changing valve seals — saving rig time during seal-replacement operations.

Key Features

• Two Product Series: Model F (F/FC/FA) for single-purpose valve retrieval, Model G (G/GA/GC/GCA) for dual-purpose retrieval + seal-retaining-ring service.
• Positive Engagement Catch: Heat-treated alloy-steel catch seats firmly into the bottom of the float valve body — no slippage under heavy pull loads.
• 90° Engagement Rotation: Standard quarter-turn engagement after catch insertion makes the puller ready for lifting.
• Integrated Bumper Stop: Built-in shoulder limits travel inside the sub / drill collar, protecting the catch from over-stress during engagement.
• Model FC Special Note: When retrieving an FC valve, the catch must be positioned to avoid contact with the releasing key.
• Dual-Purpose Model G: In addition to valve retrieval, the G-series tool assists with removing and installing the seal-retaining ring during valve-seal change-out.
• High-Strength Alloy Steel: Forged AISI 4140 / 4145 alloy steel body with through-hardening for maximum tensile and impact resistance.
• Field-Replaceable Catch: Worn or damaged engagement catches can be replaced in the field without scrapping the tool body.
• Multiple Sizes Available: Standard sizes to fit API float-valve seat diameters from 3-1/2″ to 9-1/2″ (custom sizes on request).
• Compatible with Standard Lift Tools: Top pin designed for standard wireline / drilling jars / elevator handling.

Working Principle

The CAMTOP Valve Puller is run into the well on standard wireline, drill pipe, or jar assembly until it reaches the float-valve seat inside the sub or drill collar. The engagement catch is lowered past the valve body, then the tool is rotated 90° to seat the catch into the valve’s machined extraction profile. Once seated, the integrated bumper stop shoulders against the top of the float-valve body, transferring pulling force directly from the drill string to the valve. The valve can then be lifted out and recovered at the surface.

For the Model G series, the same tool body additionally features a slot profile that matches the float-valve seal-retaining ring. This allows the operator to push the ring out of its groove for seal replacement, and to re-install a new ring during re-assembly — eliminating the need to run a second specialized tool.

Applications

• Drill Collar Float-Valve Retrieval: Remove stuck or damaged float valves from drill collars during tripping operations
• Tubing Sub Float-Valve Service: Retrieve flapper / poppet valves from landing subs and tubing accessories
• BOP Stack Float Equipment: Service float-valve assemblies inside BOP-related downhole equipment
• Workover & Plug-and-Abandon Operations: Recover float valves prior to milling or section abandonment
• Fishing Jobs: Retrieve accidentally dropped or stuck float-valve components
• Model G — Seal Change-Out: Use the same tool to remove and replace the seal-retaining ring during valve seal replacement
• Rig Maintenance Shutdown: Pull float valves for inspection and re-install during scheduled downtime
• Drill String Component Test: Service float-valve seats during drill string pressure-test preparation
