What is API 602 forged steel valve?

API 602 covers compact forged steel gate, globe, and check valves for sizes typically 1/4 inch to 2 inch (8–50 mm) in ASME Class 150–2500. Supreme Valves supplies screwed, socket-weld, flanged, and butt-weld ends in reduced bore, full bore, and standard port with designs per BS 5352, BS 6364 (cryogenic), and ASME B16.34.

What is the difference between Class 800 and Class 1500 forged valves?

Class 800 forged valves are common for utility, drain, and instrument isolation (typically 1/2–2 inch). Class 1500 and 2500 Y-pattern globe/check designs handle higher-pressure throttling and non-return service. Select pressure class to match ASME B16.34 pressure-temperature rating for your fluid and temperature.

Does Supreme Valves export API 602 forged valves?

Yes. Forged gate, globe, and check valves are exported from Ahmedabad, India with EN 10204 3.1 MTCs and API 598 hydrostatic test reports. FOB Mundra, CIF, or DAP delivery to Middle East, USA, Africa, and Asia.

How do I request API 602 valve pricing?

Provide valve type (gate/globe/check), size, pressure class, end connection, bore (RB/FB/SP), material (A105, F304, F316, etc.), quantity, and destination. RFQ: supremevalves.in/quote-builder.html · WhatsApp +91 97732 78770.

Valve Families

Straight-pattern

Gate, globe and check valves — Class 150 through 2500. Bolted body-bonnet to Class 800; seal-welded bonnet for Class 1500.

Y-pattern

Globe and check valves Class 1500/2500 per BS 5352. Near-straight flow path reduces pressure drop vs conventional globe. Y-pattern details →

Cryogenic

Gate and globe per BS 6364. Austenitic SS body/bonnet with extension column. Also available Class 150–1500.

Bellows-sealed

Gate and globe Class 800 with SS316L bellows for zero stem leakage — toxic, vacuum and fugitive-emission service.
