Non-Code Relief Valves — Economical Overpressure Protection
Not every application requires ASME certification. Equipment not governed by boiler code or pressure vessel code—process systems, test stands, equipment prototyping, and general industrial overpressure relief—often benefit from economical, non-code relief valves. Aquatrol’s non-code series deliver reliable protection without premium pricing or certification overhead.
Why Aquatrol Non-Code Valves
Many industrial applications fall outside ASME Code jurisdiction—research equipment, pilot facilities, private systems, and one-off installations. These applications still need reliable overpressure protection, but don’t require expensive third-party certification and capacity testing. Aquatrol’s non-code relief valves deliver the same engineering quality and reliability at lower cost.
Non-code valves are faster to order and less expensive to customize. You can specify unusual pressure settings, connection types, and materials without the lead time and documentation overhead of ASME-certified valves. Perfect for prototypes, test equipment, and applications where you need quick deployment and flexibility.
Even without ASME Code, these valves undergo rigorous in-house testing and validation. They use the same manufacturing standards, materials, and engineering as our certified series. The difference is third-party certification and documentation—not the valve quality. Ideal for applications where code compliance isn’t required but performance and reliability are.
| Series | Pressure Range | Media Type | Connection |
