What are the key features of the VINCER JIS Type Swing Check Valve?

The key features of the VINCER JIS Type Swing Check Valve include:

• Swing disc design for effective prevention of backflow.
• Minimal pressure drop and streamlined flow path.
• Reliable sealing for various fluid types.
• Suitable for horizontal and vertical installations.
• Constructed according to JIS (Japanese Industrial Standards).
• Durable construction with low maintenance needs.

What is the working principle of the VINCER JIS Type Swing Check Valve?

The VINCER JIS Type Swing Check Valve operates on the principle of a swinging disc. When the fluid flows in the desired direction, the disc swings open, allowing the fluid to pass through. If the flow reverses, the disc swings closed, creating a seal that prevents backflow and protects the system.

What material options are available for the VINCER JIS Type Swing Check Valve?

The VINCER JIS Type Swing Check Valve is available in various materials, including:

• Cast Iron
• Ductile Iron
• Carbon Steel (SCPH2)
• Stainless Steel (SUS304, SUS316)
• Bronze
• Alloy Steels

What size options are available for the VINCER JIS Type Swing Check Valve?

The VINCER JIS Type Swing Check Valve is available in a range of sizes, commonly including:

• 1/2″ to 48″ (DN 15 to DN 1200)

What PN pressure options are available for the VINCER JIS Type Swing Check Valve?

The VINCER JIS Type Swing Check Valve is designed for different pressure ratings, including:

Differences Between ANSI, GB, and JIS Type Swing Check Valves

1. Standards and Specifications:
   • ANSI (American National Standards Institute): Primarily used in North America. Valves are designed according to ANSI standards, which specify dimensions, materials, and testing procedures.
   • GB (Guobiao, or National Standards of China): Used in China. GB standards govern the design, materials, and testing requirements for valves in Chinese industrial applications.
   • JIS (Japanese Industrial Standards): Used in Japan. JIS standards specify the requirements for valve design, materials, and performance in Japanese industries.
2. Pressure Ratings:
   • ANSI: Typically rated by classes such as Class 150, Class 300, Class 600, etc.
   • GB: Pressure ratings are specified by PN (Pressure Nominal), such as PN 6, PN 10, PN 16, etc.
   • JIS: Pressure ratings are denoted as K, such as JIS 10K, JIS 16K, JIS 20K, etc.
3. Design and Dimensions:
   • ANSI: Valves are designed to meet ANSI B16.5, B16.10, and other relevant standards for dimensions and tolerances.
   • GB: Valves conform to GB/T 12221 for dimensions and tolerances.
   • JIS: Valves are designed to meet JIS B2031 and other relevant standards.
