Custom Valve Springs & Components Manufacturing

Valve springs and other components are some of the most critical elements in valve applications including safety relief, diaphragm, gate, globe, and high-pressure valves. MW Components manufactures valve springs to exacting tolerances (+/- 5% on rate), and we can meet the tight one-degree squareness required for critical valves.

Quality Manufacturing Throughout the US

With multiple valve manufacturing locations in the USA, we offer a wide range of high quality, domestic precision products. MW Components locations also have the engineers and precision manufacturing equipment to help you produce the highest quality product possible.

Our locations carry a range of certifications and industry approvals so you know you’re working with experienced professionals who can meet your standards. Full certifications are available from first article to 100% serialized test reports. Comprehensive testing is also available for all loads and physical dimensions, as well as SPC analyses on final test reports.
