Orbit Rising Stem Ball Valve, API 6D, A352 LCC, 8 IN, CL300

Key Specifications / Features

The Orbit Rising Stem Ball Valve Factory produces high-quality ball valves designed to meet API 6D standards. These valves are made from ASTM A352 LCC low-temperature carbon steel, ensuring durability and reliability in demanding applications. With an 8-inch (DN200) diameter and rated at Class 300 LB and PN50 pressure classes, they feature raised face (RF) flanged ends for secure connections. The valves are operated using a bevel gear mechanism, providing smooth and precise control.

Orbit Rising Stem Ball Valves are engineered for reliable shut-off service in critical applications such as oil and petroleum products, natural gas, and chemical pipelines and stations. These valves feature a unique rising stem mechanism in which the ball rotates around the body's centerline to open or close, ensuring smooth, frictionless switching. The valve's single-seat design, combined with low torque requirements and a wedge-seal structure, provides tight and dependable sealing that remains unaffected by pipeline pressure differentials. Additionally, the self-cleaning action of the sealing surfaces enhances long-term durability and service life, even under challenging operating conditions.
