Anderson Greenwood Series 90 and 9000 in brief

The Series 90/9000 is the low-pressure end of the pilot-operated family. The manufacturer describes these valves as protection for low-pressure storage vessels, tanks and low-pressure piping systems, where set pressures are far below those of a refinery process relief valve and seat tightness close to set pressure matters. Snap action and modulating pilots are both offered, and a vacuum relief setting can be included. Buyers searching for Anderson Greenwood valves, or for older Anderson Greenwood Crosby paperwork, are usually looking at the same product line.

Ordering Anderson Greenwood relief valves: what we need

Send the full model number and serial number from the nameplate, together with set pressure, vacuum setting if any, inlet and outlet size and rating, body and seat material, and the relieving case from the valve datasheet. For GCC projects, state the code basis and the test certificates you need from the manufacturer.

Frequently Asked Questions

How do I identify an Anderson Greenwood Series 90 or 9000 valve from its nameplate?
The nameplate carries the model number, serial number, set pressure, orifice or size and the capacity. The model number encodes the series, pilot type, connection sizes and materials, so please send it complete, or send a clear nameplate photo. With the serial number the manufacturer can trace the original build, which is the safest basis for a like-for-like replacement or a soft goods kit.
Where are Series 90/9000 pilot-operated valves normally used?
They are low-pressure pilot-operated relief valves, so the typical duty is tank and vessel protection: low-pressure storage tanks, vessels and low-pressure piping systems. A pilot-operated design stays tight close to set pressure, which reduces product loss compared with a weight-loaded vent. Suitability for your case must be checked against the manufacturer's sizing data.
Is Seven Star LLC a distributor of Anderson Greenwood?
No. Seven Star LLC is an independent supplier and is not an authorized distributor or agent of Anderson Greenwood. We source Anderson Greenwood valves and parts through commercial channels, check the model number against the manufacturer's documentation, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order, on request.
What should I send to get a quotation for an Anderson Greenwood relief valve?
Send the model and serial number, set pressure and vacuum setting, fluid and relieving temperature, required capacity, back pressure, inlet and outlet size and flange rating, materials, and the design code. If you only need spare parts, the serial number and a list of the parts or kit are enough for us to check the correct items with the manufacturer's documents.
