Check valve flanged type 802 DN100 149B2418

Check valve flanged – reliable installation protection

This flanged check valve, type 802, with a nominal diameter of DN100, is a key element in any installation where protection against backflow of medium is required. Made of durable cast iron GG 25 (GJL-250), it ensures long-lasting and trouble-free operation even in difficult conditions. Its design, based on a spring-assisted disc closure, guarantees tightness and minimal pressure loss.

This valve finds application in a wide range of installations, including heating and industrial systems. Thanks to its universal working position, installation is simple and flexible. The use of metal-to-metal sealing eliminates the risk of corrosion and ensures reliability in contact with various media.

Construction and characteristic features

The valve is distinguished by its solid construction and well-thought-out solutions. The cast iron body provides high resistance to pressure (PN 10/PN 16) and corrosion. The closing assembly with a parabolic disc assisted by a spring ensures quick and reliable closure, minimizing the risk of hydraulic shocks. The flanged connection facilitates integration with existing infrastructure.

• Durable material: The GG 25 (GJL-250) cast iron body guarantees longevity and resistance to mechanical damage.
• Tight closure: The parabolic edge disc assisted by a spring ensures tightness and minimizes pressure loss.
• Versatility: The possibility of installation in any position facilitates installation in various configurations.
• Temperature resistance: Operation in a temperature range from -10°C to +100°C (up to +200°C for DN65-DN200) allows the valve to be used in various environmental conditions.
• Compliance with standards: Meets the requirements of PN-EN1092-2 and PN-EN 558-1 series 49, which confirms its safety and quality.

This valve is particularly recommended for heating installations and for aggressive media, but should not be used in systems with piston pumps or compressors due to large pressure fluctuations. It is a solid choice for professionals and end-users looking for a reliable solution to protect their installations from backflow.
