FAQ
Does this butterfly valve comply with the API 609 standard?
The basic design of the entire product line strictly adheres to the API 609 specification and is also compatible with BS 5155 requirements. We can provide corresponding certificates of compliance to meet the procurement requirements of various industrial projects.
What are the advantages of triple-offset butterfly valves compared to centerline butterfly valves?
The triple-offset metal hard-seal design ensures no friction between the sealing surfaces during opening and closing. It offers superior resistance to high temperatures and pressures, resulting in a service life far exceeding that of standard centerline butterfly valves, making it suitable for harsh operating conditions involving high temperatures and high wear.
Is it difficult to install large-diameter butterfly valves?
Butterfly valves of the same nominal diameter weigh only one-third as much as gate valves, allowing for installation without the need for large hoisting equipment, which significantly reduces on-site construction difficulty and costs.
Can butterfly valves achieve precise flow regulation?
Butterfly valves feature a smooth, linear control characteristic curve. When paired with pneumatic or electric positioners, they can achieve high-precision proportional flow control, making them suitable for various pipeline applications requiring precise flow regulation.
Can metal hard-seal butterfly valves achieve zero leakage?
By utilizing high-precision, ground-matched metal sealing pairs, these valves can achieve bidirectional zero leakage, meeting the shut-off sealing requirements under severe operating conditions.
