The Saunders name has been synonymous with the diaphragm valve since we invented the technology over 75 years ago.
Today, the Saunders brand is the standard for excellence and performance in diaphragm valve technology and is widely recognised in the process industries as a leader in quality and innovation. Our expertise in diaphragm valves is equally apparent in standard two-way valves as in custom designed multi-arrangements machined from single blocks of stainless steel. 

Through a combination of knowledge and experience, we understand the relationship between a diaphragm valve and its application.
The purity and performance inherent in the Saunders brand makes our diaphragm valves ideally suited to demanding aseptic applications in the pharmaceutical and biopharmaceutical sectors. Our revised product portfollio also includes diaphragm valves to meet the specification necessary for various other cleaning applications, such as food processing.

We are committed to surpassing accepted levels of service and quality through investment and dedicated customer support.
Building on an already well-established position in highly demanding process industries, we are continually researching and implementing ways to develop diaphragm valve technology. At a product level, we employ advanced computer-aided engineering (CAE) and computer fluid dynamic (CFD) software platforms that allow us to design and manugacture products to optimise valve performance and flow conditions.
