Check valve DN50, FIG.402 402A050C52

Check valve – reliable installation protection

The check valve DN50, designated as FIG.402, is an element used to protect the installation against backflow of medium. Made of gray cast iron, it ensures durability and corrosion resistance. It is a key component in systems where maintaining the correct flow direction is required, protecting devices from damage and ensuring efficient operation.

Construction and application

This valve is characterized by a flanged connection, which facilitates assembly and disassembly in existing installations. It is designed to work with media such as glycol, industrial water and neutral agents. Thanks to its construction, the valve works in various branches of industry – from shipbuilding, through heating, to general industrial applications. It can operate in a wide temperature range, from -10°C to 80°C, which makes it a universal solution for many applications.

Key features and benefits

• Operation in any position: Valve installation does not require considering orientation – it will work correctly regardless of the installation method. This is a great convenience during modernization or expansion of existing systems.
• Low pressure drop: The valve's design minimizes flow resistance, which translates into energy savings and more efficient operation of the entire installation.
• No maintenance required: The solid construction and high-quality materials ensure trouble-free operation for a long time without the need for regular inspections or repairs.
• Strength and durability: Made of gray cast iron guarantees resistance to mechanical damage and corrosion, ensuring a long service life of the device.
• Compliance with standards: The valve meets the requirements of the pressure equipment directive 2014/68/EU and has CE marking for diameters DN≥65, which confirms its safety and quality.
• Wide range of applications: Ideal for protecting pumps, pressure reducers and other devices sensitive to backflow of medium.

The check valve FIG.402 is a solid and reliable solution for professionals and end customers looking for effective protection of their installations against the effects of backflow. Its versatility and ease of installation make it an ideal choice for various industrial and domestic applications.
