Valve Choke

Valve Choke


Refractron partners with companies which have industrial applications requiring valve components to control the flow to a certain flow coefficient or choke components to enrich the fuel mixture by partially shutting off air or reducing the air intake.  Valves control the flow of liquids, gases, slurries, or dry materials through a pipe or similar passageway, and may also control the rate of flow, volume, pressure, and direction.  Our fluid power valves are used in compressed or pressurized applications.

Our mechanical engineers assist in your component design including specialty applications that may be one-of-a-kind designs.  We can reverse engineer replacement components for any machine.  If drawings are available, the fit and function of components can be verified at the customer’s site to minimize risk and machine downtime. If drawings are not available, Refractron can measure components via a portable CMM, create drawings, modify designs if required, and provide a detailed report with insight from our experienced designers.

Refractron is ISO 9001:2008 and ITAR certified.  To service the needs of our customers, our facility is outfitted with an array of advanced equipment to produce one-off prototypes or high-volumes. Examples include a materials testing lab and a comprehensive machine shop containing advanced CNC equipment.  Parts are customized with laser marking for traceability and efficient inventory control and machined to ensure exact dimensions.

Quality assurance and testing ensure the structural integrity, dimensions, and optimal performance for each part that we make.

Custom Specifications & Capabilities

Izory®, Izory® X, and Izory® HD, developed and manufactured only at Refractron, has better abrasion and cavitation   resistance not found in steels, alloys or many other forms of ceramics and carbides.   Izory® can last longer and mitigates the stress on mating parts which reduces the operating costs on strategic equipment.

ATZ is often specified for the most demanding applications that require high strength, hardness, excellent fracture toughness, and wear and corrosion resistance.  ATZ is a composite ceramic consisting of small alumina particles dispersed in an YTZP matrix. It is unique in combining and further improving many of the best properties of the individual materials.

YTZP Zirconia has excellent strength, hardness, abrasion and corrosion resistance that make it ideal for tough applications operating at up to 850ºC. When HIPed YTZP has a near perfect fine-grained microstructure (grains <0.5µm) that can be machined and polished into sharp blades and knives, blades and valve or pump components.
