Check valve flanged type 802 DN80 149B2417

Between-flange check valve type 802 is a reliable solution to protect installations against backflow of medium. Made of cast iron GG 25 (GJL-250), it is characterized by its solidity and corrosion resistance. Designed for use with clean media, it finds application in heating, water supply and industrial systems.

This valve has between-flange connections, which facilitates installation and removal in existing installations. Pressure class PN 10/PN 16 ensures safe operation in systems with different working pressures. The plate closing mechanism, assisted by a spring, guarantees tightness and minimal pressure loss. The valve design allows operation in any position, increasing installation flexibility.

• Strength and durability: The body made of cast iron GG 25 ensures long-lasting and trouble-free operation even in difficult conditions.
• Versatility: The possibility of mounting in any position makes it easy to adapt to the specifics of the installation.
• Tightness: Plate closure with spring and metal-to-metal sealing guarantee effective protection against backflow.
• Compliance with standards: The valve meets the requirements of PN-EN1092-2 and ASA B16.1 class 125RF regarding flange drilling, as well as PN-EN 558-1 series 49 and DIN 2501 regarding installation length.
• Low pressure loss: The compact design and aerodynamic shape of the valve plate minimize flow resistance, which translates to energy efficiency of the system.

The valve is particularly recommended for heating installations and for aggressive media – although it should be remembered that it is not recommended for use with piston pumps or compressors, where there are large pressure surges. Thanks to its design, it does not generate hydraulic shocks, which further increases the safety of the installation.
