Butterfly Valve Wafer Type Gear Operated
The Butterfly Valve Wafer Type Gear Operated is designed for reliable flow isolation and regulation in water distribution, fire protection, and industrial pipeline systems. Featuring a compact wafer body and precision gear operator, it provides smooth operation and dependable sealing performance while reducing installation space and overall system weight.
The valve is manufactured with a ductile iron body, stainless steel stem, and resilient NBR seat, offering excellent durability and long service life in water applications. For larger pipeline sizes where manual lever operation becomes difficult, the integrated gearbox significantly reduces operating effort and improves control accuracy.

Typical Applications
Fire Protection Systems
Widely used in fire sprinkler networks, pump rooms, and fire water distribution pipelines where reliable shut-off performance is essential.
Municipal Water Supply
Suitable for transmission and distribution pipelines in municipal water infrastructure projects.
Building Services
Applied in commercial buildings, industrial facilities, and utility networks requiring compact installation and dependable flow control.
Industrial Water Systems
Used in cooling water, service water, and general utility pipelines across various industrial sectors.
Installation Guidelines
For optimal performance, pipeline flanges should be clean, properly aligned, and parallel before installation.
The valve disc should remain partially open during installation to prevent seat damage and facilitate alignment. After positioning the valve between the flanges, tighten bolts gradually in a cross-pattern sequence to ensure uniform flange compression.
Once installation is complete, fully cycle the valve to verify smooth operation before system commissioning.
Quality Assurance
Every valve undergoes strict inspection procedures before shipment:
Raw material verification
Dimensional inspection
Component assembly inspection
Pressure testing
Leakage testing
Final visual inspection
Test reports can be provided upon request for project documentation and quality verification.
