Product Overview
API Triple Lug Wafer Butterfly Valve is a triple-offset metal-seated butterfly valve designed for high-temperature, high-pressure, and critical shut-off applications in industrial pipeline systems.
Product Features
Triple-offset sealing geometry, allowing the disc to disengage from the seat throughout most of the opening and closing stroke.
Metal-to-metal sealing structure, maintaining reliable shut-off performance under high-temperature and high-pressure service conditions.
Lug-style wafer body, enabling independent pipeline installation and downstream maintenance without removing the entire valve.

FAQ
Q: Why choose a triple-offset butterfly valve instead of a resilient-seated butterfly valve?
A: Triple-offset valves use a metal-to-metal sealing design, making them more suitable for high-temperature, high-pressure and demanding industrial service conditions.
Q: Does the lug wafer design allow downstream pipeline maintenance?
A: Yes. The lug body allows one side of the pipeline to be isolated during maintenance, reducing the need to remove the complete pipeline section.
Q: Can the valve be supplied with pneumatic or electric actuators?
A: Yes. Manual lever, gearbox, pneumatic and electric actuation options are available according to project requirements.
Q: What technical documents are available with shipment?
A: COA is not applicable to industrial valves, but the valve can be supplied with material certificates, pressure test reports, inspection records and other project documents as required.ts.
