FORGED STEEL VALVES - Class 150 to 1500
| Size | 1/4" to 2" (8 mm to 50 mm) |
| ASME Class | Class 150 to 1500 |
| Design Standard | API 602, BS 5352, ASME B 16.34, BS 6364, MSS SP 84 |
◎ Robust structure
◎ Suitable for high pressure and temperatures (up to 540 degrees Celsius for alloy steel and 425 degrees Celsius for carbon steel)
◎ High level of integrity - The bolted body-bonnet has a spiral-wound stainless steel gasket and graphite filler to ensure high integrity sealing
◎ The Gate Valve's T-head stem-disc connection completely meets the strength criteria of API 598 and API 602
◎ High pressure valves are offered with screwed body-bonnet joint, ensuring simplicity of inspection and in-line maintenance, and minimising downtime
◎ The Y-pattern design in Globe and Check valves provides near-perfect flow, considerably reducing pressure loss and turbulence as compared to traditional designs
◎ Cryogenic Forged Steel Gate, Globe and Check Valves correspond to BS 6364
◎ Valves can be offered to meet NACE MR-0175 and other unique NACE criteria.
◎ T-pattern and Y-pattern Valves
◎ Specials: Cryogenic and Bellows-sealed valves
◎ Component Grades: A105, LF2, F5, F11, F22, F304/ F304L, F316/ F316L, F347, Monel.
FORGED STEEL VALVES - Class 1500 to 4500
| Size | 1/2" to 2" (8 mm to 50 mm) |
| ASME Class | Class 1500 to 4500 |
| Design Standard | ASME B 16.34 |
◎ Body-Bonnet Connection
These valves include a threaded body-bonnet connection. The junction between the body and bonnet is seal-welded to improve the seal
◎ Assembly of the Stem-disc
With a wire placed via a hole in the disc, the globe valve's disc is connected to the stem. The stem and disc may spin freely on this special stem-disc connection, which also allows the disc to fully align with the seat and create a tight seal
◎ Disc and Seat
Integral hard-faced and machined seats are a feature of forged steel valves that provide an extended lifespan. Standard hard-facing of 1.6 mm is available for the valves. To avoid seat damage and to guarantee correct sealing, the discs are guided during opening and closing.
◎ T-pattern Valves
◎ Component Grades: A105, F22, F91, F92, F304.
