Triple Eccentric Gear Operated Butterfly Valve High Temp WC6 WC9 Hard Seated Butt Weld End

High Temp WC6 WC9 Hard Seated Butt Weld End Triple Eccentric Gear Operated Butterfly Valve

The TEKO triple eccentric butterfly valve is designed for excellent flow and control characteristics, sealing capabilities (zero leakage) and dependability in a wide range of applications.

Triple offset butterfly valves meet industry requirements and provide low cost of ownership to end user through: improved life cycle costs, emissions control, less downtime and low maintenance costs.

Design Features

• Unique design and manufacturing techniques for an unrivalled accuracy ensures full conical pairing of the sealing components, eliminating friction and abrasion between the faces.
• Small switching resistance produces a reliable sealing performance at all times and reduces face abrasion with a vastly expanded valve life cycle.
• Bubble tight shutoff for High Pressure and High Temperature applications.
•  

Valve Testing

Life Cycle: The valve have been tested extensively under a wide range of conditions in order to validate performance of the critical components(gasket, seal stack and bearing/shaft material). The overall design and tolerances were tested rigorously to meet industry life cycle standards.

Durability: Testing was also performed to establish the durability of the seal stack and validate the overall design.

Brackish Water: TEKO valves were cycled using brackish water to validate the bearing / shaft combination and determine the effect of brackish water on standard componets.

Features and benefits:

• Triple Offset metal seat design
• Long life seats
• Bearing protectors
• Bi-directional tight sealing
• Capable of zero leakage
• Excellent throttling characteristics
• Seat design eliminates galling and minimizes seat/seal wear
• Shaft does not penetrate through seat/seal = less susceptible to seat leakage
• Shutoff is assisted by pressure = seating improves as pressure increases
• Seal is not subject to set like soft seated designs
• Self compensating seal, will not stick due to temperature fluctuations
• Larger shaft diameter with more bearing wear surface
• Robust Shaft design to support full range of actuator torques
