High Performance Wafer Butterfly Valve
High Performance Wafer Butterfly Valve features a compact wafer-style body that fits directly between standard flanges, requiring no pipe modification. This design makes it particularly suitable for installations with limited space and for retrofit applications.
Built with a ductile iron body and precision sealing system, the valve delivers stable shut-off performance under standard industrial operating conditions. The lockable handle provides clear open/close indication and helps prevent accidental operation in critical service lines.
This High Performance Wafer Butterfly Valve is commonly used in OEM skids, fire protection systems, power generation auxiliary lines, and building service piping where compact design, installation efficiency, and operational reliability are required.

Applications
Industrial Processing
Used for water, air, and mild chemical media in factory pipeline systems where compact installation is required.
Fire Protection Systems
Applied as isolation and control valve in sprinkler systems and fire water supply networks.
Water Treatment
Used in filtration units, pumping stations, and municipal distribution pipelines.
Chemical Handling (Non-aggressive Media)
Suitable for non-corrosive or mildly chemical process fluids depending on seal selection.
Power Generation
Used in cooling water circuits and auxiliary piping systems in power plants.
Irrigation Systems
Controls water distribution in agricultural and landscape irrigation networks.
OEM Equipment Integration
Designed for integration into packaged equipment, skids, and modular systems requiring compact flow control solutions.
Installation & Operation Guide
Proper installation ensures long-term performance and system safety.
Preparation
Ensure pipe flanges are clean, aligned, and correctly spaced before installation.
Positioning
Insert valve between flanges carefully, ensuring the disc is in the open position to avoid obstruction.
Bolting Procedure
Tighten bolts gradually in a cross pattern to maintain even sealing pressure.
Operation Check
Confirm the handle rotates smoothly through the full 90° range before pressurizing the system.
Pressure Testing
Perform leakage testing at system operating pressure and verify sealing integrity.
Maintenance Practice
Cycle the valve periodically if not frequently used to prevent sticking or seizure.
Safety Notice
Do not exceed rated pressure or temperature limits indicated on the nameplate.
Warning
Do not use the handle as a lever or install the valve in a space that restricts operation.
Replacement Guideline
Replace the valve if leakage, corrosion, or operating resistance is observed.
Quality & Engineering Control
Each High Performance Wafer Butterfly Valve is manufactured under controlled production processes with strict inspection at every stage, including:
Dimensional inspection
Pressure testing before shipment
Visual inspection of sealing surfaces
Material consistency verification
This ensures stable performance in fire safety and industrial water systems where failure is not acceptable.
