DIN PN16 Duction Cast Iron Body Flang Swing Non Return Check Valve

Product Description: DIN3356 Swing Check Valve

Our DIN3356 Swing Check Valve provides reliable backflow prevention in pipeline systems, ensuring fluid flows in one direction while automatically preventing reverse flow. Manufactured to stringent DIN standards, this valve features a robust ductile iron construction for exceptional durability and pressure resistance. The swing disc design offers minimal flow resistance, reducing pressure drop across the valve for improved system efficiency. With sizes ranging from DN40 to DN600 and pressure ratings of PN10 and PN16, this valve is ideal for water supply, wastewater treatment, heating systems, and general industrial applications where German engineering standards are required.

Key Features & Advantages:

• Robust Construction: Ductile iron body, bonnet, and disc provide excellent mechanical strength and longevity

• Minimal Pressure Drop: Swing disc design creates minimal flow resistance for energy-efficient operation

• Reliable Sealing: EPDM/NBR seat and gasket materials ensure bubble-tight closure and chemical resistance

• Standard Compliance: Designed according to DIN3356 with DIN3202-F6 face-to-face dimensions

• Easy Installation: DIN2531/DIN2532/DIN2533 flange standards ensure compatibility with existing piping systems
