Check valve flanged type 402 DN50 149B2282

Flanged check valve – reliable installation protection

The flanged check valve type 402 is a solid and versatile device designed to protect installations from backflow of medium. The construction based on a poppet closure system (system 02) ensures efficient operation in pumping stations, tanks, and transmission networks. The valve is particularly recommended for applications where there is a risk of water hammer.

The valve is made of high-quality gray cast iron with an epoxy coating, which ensures corrosion resistance and long-term operation. The EPDM rubber seal guarantees tightness and reliability over a wide range of operating temperatures – from -10°C to 100°C. This makes the valve suitable for various environmental conditions.

Construction and application

The type 402 check valve is characterized by a simple construction, which facilitates its installation and maintenance. It is equipped with a stainless steel spring, which allows operation in any position. The profiled body shape minimizes hydraulic losses, affecting the energy efficiency of the installation. Additionally, the valve has a cable cutout, which facilitates cooperation with submersible pumps.

The valve finds application in water installations and for the transport of clean liquids and gases. It meets the requirements of the Pressure Equipment Directive (PED) 2014/68/EU and has approvals and is in accordance with international building standards. It is an ideal solution for both professional installers and end-users looking for reliable installation protection.
