Q:What is the difference between full bore and reduced bore options?
The full bore option matches the pipe’s diameter, enabling higher flow rates with little resistance, whereas the reduced bore option features a smaller diameter, making it appropriate for smaller systems and finer flow regulation.
Q:What is the expected service life of this valve?
Thanks to its trunnion-mounted design, robust materials, and spring-loaded seats, this valve delivers reliable performance over an extended service life. With proper upkeep and routine inspections, its operational lifespan can be greatly prolonged, even when used under high-pressure and high-temperature conditions.
Q:How do full bore and reduced bore valves affect fluid flow?
Full bore valves provide minimal resistance to flow and support high flow capacity, making them well-suited for applications requiring large fluid volumes with little pressure loss. Reduced bore valves are engineered for more accurate flow control in systems where space limitations or reduced flow capacity are necessary.
