Valves

The right valve for the application

Valve selection comes down to four things: what the valve needs to do, what medium it's controlling, the operating pressure and temperature, and how often it'll be operated. Get any one of those wrong and you'll either have a valve that fails early or one that's overspecified and overpriced.

For general isolation duties — stopping and starting flow — a ball valve is usually the right answer. It's fast, it seals well, and it'll cycle thousands of times without complaint. For precise flow regulation, you want a needle or globe valve. For a system where you need unrestricted full bore flow, a gate valve is worth considering. Non-return and check valves are the answer where backflow is a risk.

Materials matter too. Brass handles most water, air and general industrial duties without issue. Stainless steel is the right call for anything corrosive, food-grade or marine. If you're unsure which material suits your application, the thread size and pressure rating in the product spec will usually point you in the right direction — or call the team and they'll sort you out.
