Quadax® Features - Highest tightness, functionality and reliability

Quadax® Features - Highest tightness, functionality and reliability

• NOMINAL WIDTH DN 50 (2”): DN 1,800 (72”) and up to 160 bar (2,320.6 psi) Available up to DN 1,800 mm (72”) and larger / available up to 160 bar (2,320.6 psi) and higher.
• TEMPERATURE RANGE from: –270 °C to +800 °C from -454 °F to +1,472 °F.
• TIGHT IN BOTH DIRECTIONS: Up to full differential pressure, round seal and seat geometry, inconel sealing seat as standard, even with changing pressure and temperature loads.
• MAXIMUM TIGHTNESS: Also in cryogenic applications.
• METAL SEAL RING: Various versions up to full metal seals possible.
• SELF-CENTERING DISC: Highest tightness even at high Δt. 
• NO MOVEMENT: Between disc and seal – therefore highest tightness with lowest wear.
• MINIMISED FLOW SHADOW: Thanks to 4-offset design. Higher KV value and flow-optimised disc profile.
• MOST MINIMUM SHAFT DEFLECTION: Even at high pressures due to load-bearing shaft feedthrough.

QUADAX ® BENEFITS SPEAK FOR THEMSELVES

EXTREME TEMPERATURE RANGES

• Same wall thicknesses all around at seat and seal
• Extreme temperatures from –270°C (-454 °F) to +800 °C (1,472 °F)
• Even large temperature differences are compensated

MAXIMUM TIGHTNESS

• Meets the highest tightness requirements
• Bubble-free tightness even in cryogenic applications
• Innovative and patented design of the seat sealing

INCREASED PROCESS SAFETY

• Low friction and low wear
• Reduced risk of failure
• Clamp-free seat geometry
• Longer service life and functionality
• Quick closing < 1 second

REDUCED PROCESS COSTS

• Higher kv/cv values and thus lower energy loss
• Smaller dimensioning of the nominal pipe width
• Smaller drives due to optimised torque effort
• Combination of shut-off and control
• Reduced maintenance costs
