TECHNICAL DESCRIPTION
Bronze check valve, with soft sealing – NBR rubber / metal, flange connection and bolted cover.
WORKING FLUID / MEDIUM
• Thermal oil, fuels, lubricating oil and flammable hydraulic oils, petroleum, boiler feed water, condensate.
• Non-flammable hydraulic fluids, sea water.
EXECUTION
• Other materials upon request.
The Bronze Flanged Check Valve DIN PN 16 is a high-performance industrial component designed to prevent backflow in pipeline systems. Engineered to meet DIN standards and rated for PN 16 pressure, this valve ensures reliable unidirectional flow control in water, oil, gas, and steam applications. Its robust bronze construction offers excellent corrosion resistance and durability, making it suitable for demanding environments in chemical processing, HVAC, marine, and general industrial sectors.Key features include a flanged connection for easy installation and maintenance, a swing disc mechanism for low-pressure drop, and a compact design that saves space without compromising performance. The valve operates automatically, closing swiftly to protect pumps and equipment from reverse flow, water hammer, and system damage. It is tested and certified to withstand temperatures up to 200°C and pressures up to 16 bar, ensuring long-term operational safety and efficiency.Applications and benefits:Prevents reverse flow in water supply, heating, and cooling systemsIdeal for corrosive-resistant requirements in marine and chemical industriesFlanged ends provide leak-proof sealing and simplify assembly/disassemblyLow maintenance due to durable bronze body and internal componentsComplies with international DIN standards for interoperability and quality assurance
