Can air valves be manufactured in specialist materials?

When would I need a specialist material?

Standard ductile iron suits most water applications. But seawater, offshore, petrochemical and other aggressive duties can need something tougher.
We can supply air valves in aluminium bronze, super duplex, stainless steel, titanium, 6MO, Hastelloy, Monel, Inconel and gunmetal, depending on the design and certification required.

Is the body material the only choice?

No. The seat, float, fasteners, coating, flange drilling, inlet and outlet arrangement, surge protection and test documentation can all be part of the specification. Choosing the right body material and getting the rest wrong still leaves you with a valve that won’t last.

What should my enquiry include?

Tell us the medium, temperature, pressure, what the valve needs to do, the material you have in mind, flange standard, coating and any inspection or documentation requirements. Specialist valves are built around the application, so the more we know up front, the better.

Quick tip: start with the medium and temperature. They narrow down the material choice faster than anything else.

Before you enquire, have ready: medium, temperature, pressure, valve duty, material specification, flange standard, coating, and documentation needs.
