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.
