Frequently Asked Questions
A double eccentric valve features an offset disc axis and seat angle to reduce friction. A triple offset valve adds a third offset (disc face tilt), allowing for metal-to-metal sealing, which is essential for extreme temperatures (450°C+) and high-pressure isolation.
For corrosive environments, we recommend 316L stainless steel for the body and disc, paired with PTFE or specialized hard seals to ensure maximum chemical resistance and prevent erosion.
Yes, unlike gate valves which are primarily for on-off service, butterfly valves are highly effective for throttling. When paired with an electric actuator and 4-20mA feedback, they offer precise regulation of fluid flow.
The worm gear reducer provides torque multiplication (typically 5:1), making it easy to operate large valves (e.g., 12-inch) and providing a self-locking feature that prevents the valve from moving due to pipeline pressure.
We employ a rigorous testing regime, including hydrostatic shell tests at 1.5x rated pressure and seat tests at 1.1x. For high-performance models, our eccentric geometry ensures a line-contact seal that eliminates leakage.
Absolutely. Our valves feature ISO 5211 mounting flanges, allowing them to be equipped with pneumatic or electric actuators that integrate directly with PLC systems for fully automated flow control.
