The T.F. Hudgins Approach

Repair. Each valve undergoes a rigorous inspection and repair procedure to ensure it meets or exceeds new valve specifications. All refurbished valves are backed by a one year warranty.

Analysis. We analyze every valve submitted for repair and assess its condition. This analysis includes complete documentation of all damage found with the mode of failure entered into our database. Our inspection, combined with your valve's repair history, enables us to quickly identify recurring reliability issues. In addition to our expert analysis, you'll get repair recommendations that go beyond traditional "quick fixes" – helping you resolve long-term problems.

Savings. Even minor improvements in valve efficiency can add up to hundreds of thousands of dollars in savings per year. We evaluate your current valve's design, along with providing documentation for any recommended changes and their calculated impact on compressor efficiency and reliability.

Diagnostic and Engineering Studies. Valve life and performance can be significantly reduced with only a slight change from a compressor's original operating conditions or original design. We provide valve design and compressor performance analysis, even gathering on-line compressor data to assure accuracy. Our recommendations are based on real operating conditions.

Engineering Support. Expert help is always available from the industry's leading valve engineers. We offer technical support, provide failure analysis, recommend improvements for existing valve designs or custom-engineer valves utilizing the latest, high-performance materials and technology.

Tracking System. Our sophisticated data tracking software enables us to quickly spot reliability issues. Chronic problems are detected, giving you effective, long-term solutions. Valves at the end of their service life are identified before even beginning a repair, saving you time and money.

Packing Case Repair

T.F. Hudgins re-manufactures worn compressor packing cases to OEM specifications. With the combined engineering and manufacturing expertise of T.F. Hudgins and Cook Compression, we have the resources to do the job accurately and efficiently.

Overview of Packing Case Re-Manufacturing

  • All cups are thoroughly inspected.
  • Cups are machined as required to original depths to ensure proper side clearance.
  • All flat surfaces are also machined to parallel so the packing rings can be at 90-degree angles to the rod. This assures a tight gas seal between the packing ID and the rod OD.
  • Sealing surfaces are lapped and inspected for cracks and other imperfections.
  • Lapped surfaces are finished to within two light bands of absolute flat. This ensures proper sealing of packing to the cup and a bottle-tight cup-to-cup seal.
  • The lapping table is routinely measured for flatness with optical equipment. This provides a flat cup for a positive metal-to-metal seal.
  • All cases are carefully assembled using genuine Cook Compression packing, gaskets, o-rings and other parts as required.

Piston and Rod Repair

T.F. Hudgins provides a comprehensive package of repair services and replacement parts for reciprocating machinery, including:
