Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Set pressure range: 0.5 to 100 bar, Max allowable pressure: 150% of set pressure |
| flow rate: | Based on required relief capacity (ASME/API standards), typically 10-1000 m³/h |
| temperature: | -40°C to +120°C |
| slurry concentration: | Not recommended for slurries >5% solids by weight; requires special trim for abrasive media |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It automatically releases excess pressure from a system to prevent equipment damage or failure, maintaining safe operating pressure.
The valve is available in stainless steel, carbon steel, and brass, with seat materials of PTFE or EPDM, depending on the application.
The set pressure range is 0.1–1.0 MPa, adjustable within this range. Selection depends on the system's normal operating pressure and safety requirements; consult the manufacturer for specific settings.
Relevant standards include ISO 5208 for leakage rate; ISO 4126-1 for set pressure range, operating temperature, flow capacity, and overpressure; ASTM A276 for material grade; and ASTM D2000 for seat material. Always verify compliance with the supplier.
