Pressure relief valves manufacturers in United States
Pressure relief valves are made by dedicated valve OEMs, general industrial valve manufacturers, and integrated OEMs that supply safety relief devices as part of larger product lines. Buyers should look for manufacturers that state they produce (factory/OEM) relief or safety valves, list applicable pressure ranges and materials, and supply documentation for set pressures and certifications.

What to specify in your RFQ
Manufacturers quote faster and more accurately when your request covers these points.
- Valve type
Direct-acting spring, pilot-operated, safety relief vs. pressure-regulating; specify which function you need.
- Set pressure and allowable overpressure
Provide required set pressure, maximum allowable overpressure and any required reseating characteristics.
- End connections and sizing
Specify pipe size, flange standard (ASME B16.5, etc.) or threaded connection and required flow capacity (Cv or relieving capacity).
- Materials and wetted parts
List required materials (stainless steel grades, brass, alloy, elastomers) and any corrosion/temperature constraints.
- Pressure rating and temperature range
Give maximum allowable working pressure (MAWP), design temperature range and any shock/cyclic duty conditions.
- Certifications and codes
Specify required certifications or code compliance (ASME Section I/ VIII, API, PED, NACE, etc.).
- Quantity and delivery
State required unit quantity, expected annual volumes, and desired lead time for quoting production and tooling impacts.
- Testing and documentation
Request factory test certificates, set-pressure test reports, material traceability and QA documentation requirements.
