Check valve flanged type 402 DN80 149B2284

Flanged check valve – reliable installation protection

The flanged check valve type 402 is a solid and versatile solution for protecting installations against backflow. The closure system based on system 02 combines hydraulic efficiency, durability and economy. It is ideal for pump stations, tanks and transmission networks where protection against hydraulic shocks and ensuring the correct flow direction are required. Thanks to the possibility of mounting in any position, this valve offers great flexibility during installation.

The valve is designed to work with clean liquids and gases, making it a suitable choice for a wide range of applications. Made of high-quality materials, such as epoxy cast iron and bronze, it guarantees long-lasting and trouble-free operation. The EPDM gasket provides excellent sealing, and the stainless steel spring allows operation in various conditions.

Construction and characteristic features

The check valve type 402 is characterized by a solid construction that ensures reliable operation even in difficult conditions. The profiled body shape minimizes hydraulic losses, which translates into energy efficiency of the installation. The internal guide sleeve made of bronze ensures smooth and precise valve operation for a long time. In addition, the body is protected against corrosion with epoxy paint, which increases its resistance to external factors.

The valve has flanged connections with a nominal diameter of DN 80 and a pressure class of PN 10, which ensures compatibility with most standard installations. The gasket made of rubber further increases the tightness of the connection. It meets the requirements of the Pressure Equipment Directive (PED) 2014/68/EU and has ACS approval, confirming its compliance with applicable norms and safety standards.

Application and benefits
