Expanding Gate Valves
Reliable leak tight isolation for demanding industrial applications.
Power Flow Company supplies Expanding Gate Valves designed for reliable shut-off in pipelines carrying air, water, oil, natural gas, and other liquid or gaseous media. Built for demanding industrial applications, these valves provide dependable isolation and long lasting performance under high pressure and high temperature operating conditions.
Manufactured in accordance with API 600 standards, the expanding gate mechanism creates a tight seal against both valve seats, ensuring excellent leak prevention and secure shut-off. The bi-directional sealing design enhances operational reliability while reducing seat wear, helping to extend valve life and minimize maintenance requirements.
The full bore flow path allows for smooth media flow with minimal pressure loss, making these valves an efficient choice for critical pipeline systems. Their robust construction and reliable sealing performance make them suitable for oil & gas, petrochemical, power generation, water treatment, and other industrial applications.
