ASME Section III

设计范围

Size Range: NPS 1/2 to 4

Pressure Class Range: 1690 to 4500

Seating Material: Metal

特点&优势

Utilizes optimized flow passages to minimize flow direction changes and reduce pressure drop

Rigid body design to minimize body distortions and minimize leakage

Eliminates side thrust issues and prevents misalignment, galling, and stem bending for increased life-time

Body bore and hardfaced seat machined in single operation to ensure concentric alignment for tight seating and minimized leakage between disc and seat

Fugitive Emission Certifications to ISO 158748-1, 2680 pressure class, CO2 Endurance Class (1500 mechanical cycles)

Fugitive Emission Certifications to API 624
