1. General Introduction
The wafer butterfly valve is a pivotal component in fluid control systems, renowned for its compact design, cost - effectiveness, and reliable performance. It is widely applied in various industries to regulate the flow of liquids, gases, and slurries.
2. Structural Features
- **Wafer - Style Design**: The wafer - style construction allows for easy installation between two flanges, saving space and reducing the overall footprint of the piping system. This design also makes it suitable for applications where space is limited.
- **Butterfly Disc**: The central butterfly disc is precisely engineered to rotate within the valve body. It can be fully opened to allow maximum flow or fully closed to stop the flow completely. The disc's shape and material are carefully selected to ensure smooth operation and efficient flow control.
- **Sealing Mechanism**: High - quality sealing materials are used to ensure a tight seal when the valve is closed. This helps prevent leakage and ensures the integrity of the fluid system. The sealing performance can withstand high pressures and temperatures depending on the specific application requirements.
3. Technical Specifications
- **Size Range**: Available in a wide range of sizes, typically from DN50 to DN1200 (or equivalent imperial sizes), to meet different piping system requirements.
- **Pressure Rating**: It can handle various pressure ratings, such as PN10, PN16, PN25, etc., ensuring compatibility with different industrial pressure levels.
- **Temperature Range**: Designed to operate within a specific temperature range, usually from - 20°C to 120°C, although special materials can be used to extend this range for extreme temperature applications.
- **Material Options**:
- **Valve Body**: Commonly made of cast iron, ductile iron, stainless steel, or other corrosion - resistant alloys to ensure durability and resistance to various media.
- **Butterfly Disc**: Materials like stainless steel, carbon steel, or coated metals are used to provide strength and corrosion resistance.
- **Sealing Material**: Options include EPDM, NBR, Viton, etc., which are selected based on the nature of the fluid being controlled, such as chemical resistance, temperature tolerance, etc.
4. Operation and Control
- **Manual Operation**: A handwheel is often provided for manual operation, allowing for easy and direct control of the valve's opening and closing. This is suitable for applications where the flow rate needs to be adjusted infrequently.
- **Actuator - Controlled**: For automated systems, the wafer butterfly valve can be equipped with electric, pneumatic, or hydraulic actuators. These actuators enable remote control and precise flow regulation, making it ideal for large - scale industrial processes and complex control systems.
5. Applications
- **Water Treatment**: Used in water supply and drainage systems, sewage treatment plants, and water purification facilities to control the flow of water and chemicals.
- **HVAC Systems**: In heating, ventilation, and air - conditioning systems to regulate the flow of air and water, ensuring efficient temperature control.
- **Chemical Industry**: For handling various chemicals, acids, and alkalis, where corrosion resistance and reliable sealing are crucial.
- **Power Generation**: In power plants, it is used to control the flow of steam, cooling water, and other fluids in different processes.
6. Advantages
- **Cost - Effective**: Compared to other types of valves, the wafer butterfly valve is relatively inexpensive, making it a popular choice for large - scale projects.
- **Low Pressure Drop**: Its streamlined design results in a low pressure drop across the valve, reducing energy consumption in the fluid system.
- **Quick Operation**: The butterfly disc can be rotated quickly to open or close the valve, enabling rapid response in emergency situations.
- **Easy Maintenance**: With a simple structure, the wafer butterfly valve is easy to disassemble, inspect, and repair, minimizing downtime during maintenance.

Product Quality Assurance
Quality Commitment and Inspection: Before leaving the factory, valves need to undergo strict quality inspections, such as pressure tests, sealing tests, etc. It is ensured that there are no casting defects like sand holes or air holes in the valves, and there are no bruises or scratches on the flange sealing surfaces. The markings of flow rate, direction, nominal pressure, diameter, material, etc. are clear and complete. It is promised that the valves are produced and inspected in accordance with national standards, and unqualified products will not leave the factory.
Warranty Period Service: Provide a certain period of warranty service. During the warranty period, for malfunctions caused by product quality problems, the manufacturer will repair or replace parts free of charge.
Technical Support
Pre-sales Consultation: Before customers purchase valves, provide them with professional technical consultations, including suggestions on product selection, specification parameters, material characteristics, applicable working conditions, etc., to help customers choose the most suitable valve products.
Installation Guidance: Provide installation guidance services, which can be carried out online (such as by phone, video, installation manuals, etc.) or offline (by sending technicians to the site) to ensure that the valves are installed correctly and avoid problems caused by improper installation.
Usage Training: Provide usage training for customer operators, enabling them to be familiar with the operation methods of the valves, key maintenance points, knowledge of troubleshooting common faults, etc., and improving the customers' ability to use and maintain the valves.
Supply of Maintenance Parts: Ensure the timely supply of maintenance parts. For the damage of parts outside the warranty period, provide the parts at a reasonable price (such as the cost price).
Regular Follow-up Visits: Regularly conduct follow-up visits to customers, understand the usage situation of the valves, and collect customers' feedback opinions, so as to improve the products and services.
