Anderson Greenwood Safety & Relief Valves Alternative
A drop-in safety & relief valves equivalent to Anderson Greenwood — API 6D / ASME B16.34 certified, fully documented, quoted in 24 hours. Cross-reference, specifications and why engineers switch, below.
Is there an alternative to Anderson Greenwood safety & relief valves?
Yes. Vajra Industrial Solutions manufactures and supplies safety & relief valves to the same standards and service envelope as Anderson Greenwood (Pilot-operated safety relief valves, pressure relief valves, and instrumentation valves for oil & gas and petrochemical). We match the pressure class, body and trim material, end connection and standard, and deliver with EN 10204 3.1 certification — typically at a better lead time and total cost. Share the Anderson Greenwood model or datasheet and our engineers confirm the exact equivalent within 24 hours.
Anderson Greenwood → Vajra Cross-Reference
| Anderson Greenwood Series | Type | Vajra Equivalent | Notes |
|---|---|---|---|
| Anderson Greenwood Series 90 POPRV | Pilot-Operated Safety Relief Valve | Pilot-Operated Safety Relief Valve API 526 | Modulating or snap-action pilot, CDTP ≤10% of set pressure, API 526 orifice D–T |
| Anderson Greenwood Type 727 / 81P | Direct Spring Safety Relief Valve | Spring-Loaded Safety Relief Valve API 526 | API 526, API 527, ASME Section VIII UV stamp, set 0.5–200 barg |
Why engineers switch from Anderson Greenwood
- Anderson Greenwood (Emerson) safety valves carry a significant premium - often 3–5× cost of API 526-compliant alternatives for non-critical service
- Pilot-operated safety valves are over-specified for standard ASME Section VIII vessel service where direct-spring SRVs suffice
- API 526 direct-spring safety relief valves for utility and process service available with short lead times
- Replacement spring cassettes, pilots, and soft goods kits for existing POPRV installations available promptly
The Vajra advantage
- API 526 safety relief valves - orifice sizes D through T, WCB/SS 316/Duplex body
- ASME Section VIII UV stamp and National Board certification available
- API 527 seat tightness tested - 0 bph or 40 bph leakage per orifice size
- Pilot-operated safety valves for back-pressure service and set pressure <10% CDTP
- Full documentation: datasheet, ASME U-stamp certificate, material certificates 3.1
