Product Description
1. General Introduction
The Japanese standard wafer - type butterfly valve is a high - performance valve designed and manufactured in accordance with Japanese industrial standards. It is widely used in various pipeline systems to control the flow of fluids, offering reliable performance and long - term durability.
2. Structural Features
- Wafer - Type Design: This valve is designed to be installed between two pipe flanges. It is compact in structure, which saves space in the pipeline system. The wafer - type connection makes installation and removal quick and easy, reducing maintenance time and costs.
- Butterfly Disc: The butterfly disc is the key component for controlling the flow. It rotates around the valve stem to open or close the valve. The disc is precisely machined to ensure smooth operation and tight sealing.
- Sealing Mechanism: It is equipped with high - quality sealing materials, such as rubber or PTFE seals. These seals provide excellent sealing performance, preventing leakage even under high - pressure conditions. The sealing design also reduces wear and tear, extending the service life of the valve.
- Valve Stem: The valve stem is made of high - strength materials, ensuring stable transmission of torque. It is connected to the butterfly disc and the actuator, enabling the valve to be opened and closed accurately.
3. Technical Parameters
- Nominal Diameter: Ranging from DN50 to DN1200, covering a wide range of pipeline sizes to meet different application requirements.
- Nominal Pressure: Available in 10K, 20K, etc., which can adapt to different pressure levels in pipeline systems.
- Working Temperature: Generally from - 29°C to 550°C, suitable for various working environments.
- Connection Standard: Complies with Japanese standards such as JIS B2212, JIS B2213, and JIS B2214 for flange connection dimensions, ensuring compatibility with Japanese - standard pipeline systems.
- Structural Length: Conforms to JIS B2002 - 1987, providing a standardized length for easy installation in the pipeline.
- Pressure Test: Conducted in accordance with JIS B2003 - 1987 to ensure the valve's pressure - bearing capacity and sealing performance.
4. Material Selection
- Valve Body: Commonly made of materials such as carbon steel (WCB), stainless steel (304, 316), etc. These materials offer good mechanical properties and corrosion resistance, suitable for different fluid media.
- Butterfly Disc: Usually made of the same material as the valve body or with a special surface treatment to enhance wear resistance and corrosion resistance.
- Valve Stem: Made of high - strength stainless steel or alloy steel to ensure reliable operation.
- Sealing Material: Rubber (such as NBR, EPDM) or PTFE is used for sealing, providing excellent sealing performance and chemical resistance.
5. Driving Modes
- Manual: Operated by a handwheel, suitable for applications where manual control is sufficient, and it is simple and cost - effective.
- Worm Gear: The worm - gear drive provides a mechanical advantage, allowing for easier operation, especially for larger - sized valves.
- Pneumatic: Driven by compressed air, it offers fast opening and closing speed and is suitable for applications requiring rapid response, such as automatic control systems.
- Electric: Powered by an electric motor, it can be easily integrated into automation systems, enabling remote control and intelligent operation.
6. Application Areas
- Petrochemical Industry: Used in pipelines for transporting various petroleum products and chemical substances, where reliable flow control and corrosion resistance are required.
- Power Generation: Applied in power plants for controlling the flow of water, steam, and other fluids in cooling systems, boiler systems, etc.
- Water Treatment: In water supply and drainage systems, sewage treatment plants, and desalination plants, it helps to regulate the flow of water and ensure the normal operation of the system.
- Food and Beverage Industry: Suitable for pipelines in food and beverage production, meeting hygienic requirements and ensuring the quality of products.
7. Quality Assurance
- Manufacturing Process: The valve is manufactured using advanced production technology and strict quality control procedures. Each valve undergoes multiple inspections during the manufacturing process to ensure its quality meets the standards.
- Testing: Comprehensive tests, including pressure tests, leakage tests, and performance tests, are carried out to ensure that the valve can operate safely and reliably under various working conditions.
