KITZ Aluminum Butterfly Valves are designed with a unique neck construction that supports various pipe layouts, installation positions, and demanding industrial environments.
SPECIAL FEATURES OF KITZ ALUMINUM BUTTERFLY VALVES
• Easy valve-to-flange centering: The lightweight aluminum valve body (only one-third the weight of KITZ’s conventional cast-iron butterfly valves) makes valve-to-flange centering easier during installation.
• Wide range of service applications: The austenitic stainless-steel disc provides superior corrosion resistance, ensuring long-term durability across diverse industrial applications.
• Stabilized operating torque: Dual stem bearings on the top and bottom prevent galling and stabilize operating torque, allowing smooth, consistent disc rotation.
• On-site actuator assembly: All valve necks feature ISO 5211–compliant actuator
mounting pads, enabling direct and easy on-site actuator installation.
• Prevention of dew condensation: The long stainless-steel neck minimizes
heat transfer from fluid to operating devices, reducing the need for insulation.
Gear-operated valves also experience reduced condensation in cold-water applications.
• Rust prevention: Major components such as stems, discs, necks, connectors, and endplates—along with stopper plates, washers, and bolts—are manufactured from stainless steel, ensuring superior rust resistance.
• S-shaped spherical disc (patented): KITZ’s patented S-shaped disc design ensures uniform contact with rubber liners, enhancing sealing performance while reducing operating torque. The 360° shut-off design increases rubber liner life. (Applicable for sizes 2" and above.)
• Advanced KITZ EPDM seats: EPDM seats are designed with multiple performance-enhancing features:
- High sealing reliability
- Extended service life
- Self-reinforcing back ribs to prevent distortion, skidding, and liner exfoliation caused by pressure and friction
- Wider disc seating contact for superior sealing
- Dual stem seal bearings for stabilized sealing performance
- Gasket-less flange sealing for easier valve mounting
