Drill Pipe Float Valve Size Chart and Installation

drill pipe float valve size chart

High-performance drill pipe float valves are crucial for consistent fluid control throughout the drilling process. Also known as non-return valves, this type of down hole valve prevents undesirable fluids from backing up into the drill string any time the drilling crew is making or breaking connections.

For this reason, it is crucial to properly select and install the right Drill Pipe Float Valves.  

But don't stress about it, we've got the perfect Drill Pipe Float Valve size chart and installation steps for you.

What is a Drill Pipe Float Valve?

Drill pipe float valves, or non-return valves, are downhole valves that create barriers to prevent the unwanted flow of fluids up the drill string. The valve locks down the flow of fluids while the crew at the rig floor are making or breaking connections.

Finding the best fit for every individual project is important, and the different types go beyond just the split between the F-type plunger valves and the G-type flapper valves.

How are Drill Pipe Float Valves installed?

Drill Pipe Float Valves are easily installed by following these steps:

  1. Determine the size of the Drill Pipe Float Valve (DPFV) to be installed according to the size and type of connection they are being installed into.  Refer to the Tool Joint specification chart below.
  2. Visually inspect the bore of the float sub or drilled out drill collar, and bit sub for shavings and/or foreign objects that could damage the seals of the DPFV.  Next, clean out the bore as needed.
  3. Lubricate the side seals of the DPFV using hydraulic oil and insert the valve into the bore of the float sub (or the drilled out drill collar) - to do so, rotate the DPFV slightly while inserting, this will lessen the force required and the chances of damaging the side seals.

*Caution must be taken to ensure that the DPFV is always installed with the top of the valve facing upward in the string.

 CAUTIONS 
  1. The top of the DPFV must be facing upward in the string.
  2. Fill the drill pipe regularly while running (tripping) in.
  3. If running multiple DPFV’S in the same string it is recommended they are separated.

The Keystone Energy Drill Pipe Float Valves

We make a Baker®-style drill pipe float valve that is better than the original.

For example, we use a better-quality spring and better materials throughout. Inconel® or stainless-steel springs come standard on all Keystone valves and are significantly more resistant to corrosion when compared to standard service springs provided by most other manufacturers.

Keystone valves come with certifications (traceability).

Keystone started stenciling each float valve with an independent serial number and a work order so we can trace the origin.

Keystone also offers private labeling on its Float Valves.
