YVI Cast Steel Globe Valves are designed, manufactured, and tested in accordance with ASME B16.34, API 623, and API 598. Items have been examined in accordance with API RP-591 and are Low Emissions Certified to API 624, ISO 15848-1, and TA Luft. YVI offers sizes ranging from 2” through 24” diameters in pressure classes 150# through 2500# with end configurations in either RFFE, RTJ, and Buttweld. YVI also has the capabilities to automate valves in-house using pneumatic, hydraulic, or electric actuation. Common materials of construction such as WCB, LCB, LCC, WC6, WC9, C5, C12, and Austenitic Stainless Steel Grades are all available along with other materials upon request. To ensure casting quality, all pressure-containing castings are produced in-house.
