Why Choose the CVS-290?

Revolutionary Sealing, Zero Leakage: The groundbreaking six-eccentric, cone-to-cone metal seal design eliminates friction and wear, achieving absolute bi-directional zero leakage and a surface finish (Ra 0.156μm) that guarantees performance up to 1100°C. Lower Torque, Lower Total Cost: A patented kinematic design reduces operating torque by over 30% compared to triple offset valves, allowing for smaller, more economical actuators and reducing long-term operational costs. Simplified Maintenance, Extended Life: The non-rubbing seal and protective guide cone design prevent damage and simplify maintenance. No special lapping is required, dramatically reducing downtime and total cost of ownership.

Wesentliche Merkmale

Six-Eccentric Cone-to-Cone Metal Sealing
Innovative six-eccentric geometry eliminates friction during seating and unseating, delivering true bi-directional zero-leakage performance.
Absolute Zero Leakage Performance
Precision-machined sealing surface (Ra 0.15 μm) ensures bubble-tight shut-off under extreme operating conditions.
Ultra High Temperature Capability
Designed to operate from -60°C to 1100°C (-76°F to 2012°F), suitable for ultra-high-temperature steam, gas, and thermal oil systems.
Reduziertes Betriebsdrehmoment
Patented kinematic design lowers torque requirements by over 30% compared to traditional triple offset butterfly valves, enabling smaller actuators and reducing energy consumption.
