Reciprocating Compressor Parts, Valves, and Services

T.F. Hudgins, an Allied Reliability brand, provides a wide range of reciprocating compressor parts and valves from world-class manufacturers backed by sophisticated engineering, modeling, FEA and dynamics simulation systems, as well as responsive factory and field support to ensure you find the solution you need to keep your compressors running smoothly.

Components

Compressor Valves

From precision-crafted metal plate valves to the latest, high-performance designs with non-metallic internals, T.F. Hudgins offers valving solutions for any reciprocating compressor, in any type of service.

T.F. Hudgins provides complete valve assemblies, as well as plates, discs, rings, buttons, poppets, damper plates, spring plates, leaf springs, and other metallic and non-metallic components for any make or model valve.

Together with the resources of Cook Compression, T.F. Hudgins delivers an unparalleled combination of resources to optimize your valve performance, including extensive engineering services, advanced valve dynamics simulation, sophisticated three-dimensional modeling, Finite Element Analysis, and innovative materials development programs.

Valve Restraints

For improved safety, stronger valve retention, reduced fugitive emissions, and more reliable sealing, T.F. Hudgins offer both conventional-style and Cook Compression HSR high-security valve restraints. All designs provide stronger retention with less maintenance than ordinary jack-bolt restraints.

Restraints may be easily field-retrofitted for most compressors and are available with pneumatic unloader assemblies.

Capacity Controls

Capacity controls from T.F. Hudgins help you improve compression efficiency, reduce power consumption and prolong driver life. We offer custom-engineered plug unloaders, finger unloaders, and clearance pockets in a variety of configurations.

Capacity control solutions from T.F. Hudgins are a viable alternative to cylinder modification or replacement, allowing more efficient operation over a wider range of conditions without the expense of new equipment.

Most compressors can be retrofitted in the field and manual unloaders can be converted to pneumatic actuation.

Piston and Rider Rings

T.F. Hudgins provides solutions to your most demanding applications, optimizing ring geometry, features, dimensions, and materials to reduce loads and deliver maximum service life.

Backed by the manufacturing expertise and technical resources of Cook Compression, we offer a wide variety of piston ring and rider materials, all tested through Cook Compression's in-house engineering analyses, materials laboratory, and test compressors. Materials include specially engineered alloys and high-performance thermoplastics, as well as cast iron and bronze.

Comprehensive engineering assistance is available to determine the optimum ring for your application.

Packing Cases

T.F. Hudgins offers a wide assortment of packing cases that are suitable for use at pressures ranging from vacuum to 50,000 psi environments. For lubrication, venting, purging, cooling, or other custom-engineered features, T.F. Hudgins delivers proven solutions:

Material options for all gases and pressure conditions
Advanced hyper sealing components
Cases for non-lubricated service
Vented and buffered cases specially designed to reduce fugitive emissions
Custom-engineered packages

Packing cases may be combined with specially designed rings, control systems, and/or secondary containment systems in high-performance engineered packages, including VORTEX® cooled packing cases, "Hyper" high-pressure sealing components, and STATIC-PAC® shutdown seals.

Rod Packing

T.F. Hudgins offers seal ring, pressure breaker, and wiper ring solutions from the leading manufacturer of sealing products: Cook Compression. We supply rod rings in an array of design options, with material choices from bronze to high-performance non-metallics. We routinely custom-engineer packing with materials and designs optimized for specific applications.

The combined resources of T.F. Hudgins and Cook Compression give you extensive engineering and field support, backed by more than a century of experience in tens of thousands of successful installations.

Pistons

T.F. Hudgins supplies both single-piece and segmental piston designs in a wide assortment of materials and specifications. Pistons are machined from cast iron, aluminum, or custom-specified materials.

If needed, we can custom-engineer pistons to meet specific application requirements. To assure that piston designs meet or exceed maximum load requirements, each new design is carefully analyzed using Finite Element Analysis (FEA) and evaluated based on years of practical experience.

Advantages

Single-piece or segmental pistons available in a wide array of sizes and specifications
Custom-engineering to solve special application problems
Fast turnaround
Segmental designs simplify maintenance and allow more cost-effective operation
Meets or exceeds OEM specifications

T.F. Hudgins makes it easy to get replacement pistons that meet or exceed OEM specifications. Our extensive database of piston drawings includes all major compressor makes, including Ariel, Chicago Pneumatic, Clark, Cooper, Energy Industries, Gardner-Denver, Ingersoll-Rand, Joy, White Superior, and Worthington. Pistons can also be manufactured according to your sample.

Engineered Coatings

T.F. Hudgins offers a variety of surface treatments for pistons, rods, cylinders, and other components, including:

Induction Hardening
PlasKote50+® Coating
Tungsten Carbide Coatings
Nitrite Coatings
P.T.F.E. Coatings

Cylinder Liners

T.F. Hudgins provides both new cylinder liners, manufactured to your specifications, as well as maintenance for your existing liners. You can trust our extensive experience to guide your decision. Our repair services enhance the reliability of your cylinder liner, extending its life and reducing maintenance costs.

If your compressor cylinder doesn’t have a liner, that’s not a problem; in many instances, we can return the running bore of your cylinder to as-new condition and have your compressor up and running like new in no time. To ensure the integrity of our repairs, we always perform non-destructive testing of all components and perform hydrostatic testing if the repair scope dictates to further ensure mechanical reliability post-repair.
