Special Valve Manufacturer in Canada

Engineered for severe operating conditions, special valves provide dependable flow control and excellent resistance to corrosion, extreme temperatures, and demanding process environments. ValvesOnly Canada, a prominent Special Valve Manufacturer in Canada, manufactures premium corrosion-resistant valves for industries across Toronto, Calgary, Edmonton, Vancouver, Montreal, and throughout Canada.

Why Are Special Valves Used?

Any process system will inevitably encounter situations where the performance of conventional materials in valves gets tested and fails, whether because of high exposure to chlorides, aggressive acids, wide variations in temperature, or corrosive process fluids. These are precisely the areas in which special valves come in handy. The valve itself is enhanced in terms of its materials to meet the challenge.

How to Choose the Right Valve Material?

Duplex Steel – combines high strength with strong chloride resistance, a reliable choice for offshore platforms and process systems
Super Duplex – takes that resistance further, standing up to pitting and crevice corrosion in aggressive marine environments
Alloy 20 – built for acidic service, particularly sulfuric acid and chemical processing lines
Hastelloy – engineered for some of the most corrosive chemical service conditions in industrial processing
Inconel – holds up where high temperature and high pressure combine
Incoloy – suited to thermal cycling and corrosive process environments together
Titanium – the material of choice for seawater exposure and desalination systems
Aluminium Bronze – performs reliably in marine and brackish water service
Bronze – a practical option for water distribution and general marine applications
