Productbeschrijving
The 3-Cx resilient seated butterfly valve features a molded-in seat design for durability and reliability. The precision profiled disc sealing edge extends the valve life by reducing seat wear. With its upper and lower stem bearings the 3-Cx operating torque is reduced and reliability increased.
KEY ELEMENTS
- Molded-in seat design for durability and reliability
- Lug version allows for bi-directional sealing at full rated pressure
- Precision profiled disc sealing edge extends the valve life by reducing seat wear
- Upper and lower stem bearings reduce operating torque and increase realibility in high cycle applications
- Reduction in torque enables optimized actuator selection resulting in cost savings over the valve’s lifetime
- Extended neck to allow for simplified pipe insulation
