As indicated by the title, we specialise in the production of non-standard valves – either the material of construction, or the design, or a combination of both, make our valves a special product.
This has been our core business over the past
60 years, during which time we have designed and manufactured more than 22.200 different valve products.
Design work is implemented using 3-D CAD and our computer software then initiates the manufacturing process in our factory workshops.
Milling, turning and drilling operations then produce the valves to your exact specification.
In addition to our common design software we use advanced software to make flow calculations to support the design process. This enables us to simulate the flow conditions in the client’s system in order to design very precisely. It optimizes the performance of the valve in the system.

This catalogue highlights our general valve specifications and gives a short impression on the expertise at Merwede Valves.
