Check valve FIG.287/31 DN 40 PN 16 287A040C31

Check valve FIG.287/31 is a reliable solution for protecting installations against backflow of medium. This model, with a diameter of DN 40 and a nominal pressure of PN 16, finds application in a wide range of installations – from domestic heating and hot water systems, through steam installations, to demanding conditions in industrial technologies.

Design and application

The valve is characterized by a flanged connection method, which facilitates assembly and disassembly in existing installations. The flanges are drilled according to EN 1092-1 (execution F) and EN 1092-2 (executions A, C, E) standards, ensuring compatibility with various installation elements. The installation length compliant with EN 558-1 series 1 standard guarantees proper fit to standard flange spacing.

The valve has been designed with safe and environmentally friendly use in mind – it requires no maintenance and provides a tight seal confirmed by a certificate of conformity with EN 12334 standard. It also meets the requirements of the pressure equipment directive 97/23/EC and has the CE marking for diameters from DN32 upwards.

• Ideal for protecting hot and cold water installations where precise valve operation is crucial for user comfort.
• Works well in systems using steam, where resistance to high temperatures and pressures is important.
• An excellent choice for industrial applications where reliability and durability are a priority.
• Can be used with various chemically inert media, increasing its versatility.
• Will work in heating and cooling systems, ensuring optimal operating conditions.
