ManufacturerSupreme Valves India, Ahmedabad, Gujarat, India
Y-pattern globe valves with 45-degree body angle for high-pressure service where pressure drop must be minimised. The straighter flow path provides 40--60% lower pressure drop than equivalent T-pattern globe valves, reducing pumping energy and erosion. ASME B16.34 / API 600 compliant. Renewable seat ring with Stellite overlay for extended trim life.

Notes
- Flow direction must be specified by the purchaser: under-the-disc (best shutoff) or over-the-disc (best throttling).
- For high-temperature steam service (> 425 deg C), material upgrade to WC6 or WC9 is required.
- For cryogenic service (below -29 deg C), extended bonnet and low-temperature materials (ASTM A352 LCC) are required.
- All valves are manufactured by Supreme Valves India as per our standard specifications.
