Advanced HVOF and plasma coating solutions, backed by a century of combined expertise in spherical sealing performance.
In this business, results speak louder than claims. Ours are built on three generations of
hands-on experience and a workforce whose combined knowledge spans over a
hundred years in thermal spray and valve sealing technologies. We understand what’s
at stake—performance, reliability, and longevity under the harshest conditions—and we
deliver with consistency that only comes from doing this work day in and day out.
Our valve services division is purpose-built for precision. From coating to finishing,
every step is controlled, measured, and executed with discipline. We don’t chase
shortcuts. We refine processes, hold tight tolerances, and stand behind surfaces that
perform exactly as intended—cycle after cycle.
Spherical lapping produces true, continuous contact across the entire radius, ensuring precise geometry and uniform surface conformity for optimal sealing performance.
Purpose-built for final finishing of spherical surfaces, where geometry and roundness are held to exacting standards and surface finishes are refined to ultra-low Ra values.
Mate-lapped ball and seats create a uniform, high- integrity sealing interface, delivering smooth surface finishes and consistent, leak-tight performance.
Precision-finished ball and seat geometry ensures repeatable, zero-leakage sealing under demanding service conditions.
High Velocity Oxy-Fuel (HVOF) coatings applied to spherical geometries demand more
than technical capability—they require control. We specialize in uniform, high-density
coatings that enhance wear resistance while maintaining critical geometry.
Our plasma-applied ceramic coatings are engineered for extreme environments. Whether
it’s corrosion resistance, thermal protection, or extended service life, we apply coatings
that perform where conventional materials fall short. Each application is tailored to the
operating conditions, ensuring durability where it matters most.
True spherical accuracy is not negotiable in valve performance. Our precision grinding
processes are designed to maintain exact geometry while achieving the surface finishes
required for optimal sealing. Every component is handled with care and verified against
strict tolerances.
Sealing is everything. Our 360-degree mate lapping process ensures full surface contact
between components, delivering the tightest possible seals. This is where experience
shows—knowing how to bring two surfaces together so they perform as one, minimizing
leakage and maximizing reliability over time.
Dedicated lapping systems designed for uniform material removal and consistent results on spherical sealing surfaces.
Skilled operators with more than a century of combined expertise in mate lapping ball and seat assemblies to achieve zero-leakage sealing performance.
Coatings combined with grinding and lapping for complete valve component processing and refurbishment.
Careful inspection ensures surface finish, geometric accuracy, and sealing performance meet specification before delivery.
