We cast our own bodies

From a machining shop to a valve plant

We began as a precision CNC machining workshop, cutting parts to tight tolerances for other manufacturers. That machining background became the advantage: in 1995 the plant was set up to build its own product — stainless steel ball valves — and the same precision work went into them.

The range grew in-house — one-piece, two-piece, three-piece, flanged, three-way and sanitary builds, each worked on for sealing, durability and batch-to-batch consistency. As customer systems became automated we added pneumatic actuation, so a valve can leave here already assembled and ready to install.

Today the plant runs precision machining, its own foundry, valve development and actuator assembly on one site. That combination is what lets us take on custom work — including ball valves built to spec for facility piping in semiconductor and hi-tech plants. It is also why OEM and ODM projects fit us: the machining, the casting and the assembly are all decisions we make here.

What we are

A factory, not a trading house

Own foundry, own assembly floor, running since 1995. When you send a specification it is priced by the people who will actually make the part.

What we make

Stainless as standard, other materials on request

The standard line is stainless — CF8 and CF8M. Ball valves in one-piece, two-piece, three-piece, flanged, three-way and sanitary builds, Y-type strainers, vacuum valves and complete pneumatic assemblies.

Custom work is not limited to those two grades. If your drawing calls for a different material, including carbon steel, send it over and we will quote it.

How we work

We would rather run production than a sales network

That is why the OEM side suits us. Brands, skid builders and distributors bring the customer and the specification; we bring the plant.

Paperwork we can provide

Paperwork, not promises

ISO 9001 and CE. A mill test report for the body material on request. Nothing claimed that we cannot put on paper.

Quality & certification

Checked at each stage, not just at the end

Quality is checked at each stage, from machining through to final assembly. Manufacturing runs under an ISO 9001 quality management system and products carry CE marking.

Markets we ship to

North America, Europe, Southeast Asia, the Middle East and Australia.
