Pressure Rating: Suitable for medium to high-pressure systems
Temperature Range: Suitable for -20°C to 120°C, ideal for various fluid types and conditions
Design: Swing disc mechanism that ensures positive closure when backflow occurs
Connection Type: Flanged or threaded for easy installation in various piping systems
Compliance: Meets ISO 9001, ANSI, and DIN standards for valve manufacturing
Features and Benefits
Backflow Prevention: The swinging disc mechanism allows for automatic closure when flow direction reverses, preventing backflow and protecting the system
Durable Construction: Available in high-quality materials like cast iron or stainless steel, offering long-lasting performance in both high-pressure and chemical environments
Efficient Operation: The swing valve opens and closes smoothly, ensuring minimal flow resistance when in operation
Corrosion Resistant: The materials used ensure resistance to rust, chemical degradation, and wear, making the valve suitable for harsh environments
Versatile Use: Ideal for water pipelines, chemical systems, HVAC systems, and industrial applications
Easy Installation: Flanged or threaded ends make the valve easy to integrate into existing piping systems
