ValvTechnologies, Inc., with operations in Houston, Texas, has extended bi-directional sealing technology to its 5/8” bore V series high-performance metal seated ball valves, designed to provide zero-leakage for customers in the fossil power and nuclear generation markets.
The bi-directional design prevents the upstream load spring from collapsing in a reverse flow or back pressure condition. The design ensures the integrity of the seating of the high pressure end, subsequent to any reverse flow condition. This guarantees class V shutoff in the reverse direction after an upset condition. Valvtechnologies’ V series designs can be utilized in bi-directional applications where gate valves are used without the worry of internal damage, typical of metal seated ball valve designs.
