Check valve flanged type 402 DN100 149B2285

Flanged check valve type 402 is a reliable device designed to protect installations against backflow. Made of cast iron, it guarantees durability and corrosion resistance, making it an ideal solution for both industrial and domestic applications. This model is characterized by easy assembly and disassembly thanks to flanged connections.

This specific model, with a nominal diameter of DN100 and a pressure class of PN10, is particularly recommended for systems requiring high hydraulic performance with low flow resistance. The EPDM seal ensures tightness, and the design allows operation in any position. The valve meets the requirements of the Pressure Equipment Directive (PED) 2014/68/UE.

Construction and materials:

• The valve body is made of epoxy-coated gray cast iron, providing protection against corrosion.
• The closing assembly consists of gray cast iron, brass and bronze, guaranteeing strength and reliability.
• The EPDM gasket provides excellent sealing over a wide range of operating temperatures – from -10°C to 100°C.
• The internal guide sleeve made of bronze extends the valve's life and ensures smooth operation.
• A stainless steel spring allows the valve to be mounted in any position.

Application:

Flanged check valve type 402 is used in:

• water and sewage installations,
• heating systems,
• industrial process installations,
• irrigation systems,
• wherever backflow prevention is required.

Thanks to its versatility and solid construction, it is an optimal solution for a wide range of applications. The profiled body shape minimizes hydraulic losses, and the ability to cooperate with other installation elements increases its functionality. This valve is particularly recommended for installations exposed to water hammer.
