Triple Offset Butterfly Valve
XURI is a triple offset butterfly valve manufacturer specializing in high-temperature, high-pressure, and zero-leakage applications for power plants, oil and gas facilities, and industrial process systems.
The triple offset design creates a non-rubbing metal sealing system, eliminating seat deformation and jamming caused by severe thermal cycling. Our NPS 20 Class 900 high-temp version was awarded the Gold Medal at the International Valve Expo for zero-leakage performance in severe power station service.
Engineering Advantages:
- Patented multi-level metal sealing structure
- Zero-leakage performance in severe service
- Excellent thermal cycling resistance
- Low operating torque with non-rubbing closure
- Available with hydraulic/pneumatic quick-close actuators
- Sizes from DN50 to DN3000
Typical Applications
- High-temperature flue gas isolation
- Steam turbine bypass isolation
- Hot air duct isolation dampers
- Fired heater flue gas service
