Check valve DN80, FIG.402 402A080C52

Check valve – reliable installation protection

This cast iron check valve, with a nominal diameter of DN80 and designation fig. 402, is a key element of every installation where protection against backflow is required. Made of durable grey cast iron, it ensures long-lasting and trouble-free operation in a wide temperature range – from -10°C to 80°C. Designed to operate at a nominal pressure of 16 bar, it is perfect for water, heating and industrial systems.

The valve is characterized by its versatility – it can be mounted in any position, making it easy to install even in hard-to-reach places. The design minimizes pressure loss, affecting the efficiency of the entire system. Importantly, the valve does not require regular maintenance, which translates into saving time and operating costs.

Construction and application

The check valve fig. 402 with flanged connection is a proven element of industrial fittings. Its task is to prevent the medium from flowing back in the installation – water, glycol or other liquids. This protects pumps, boilers and other equipment from damage caused by backflow and ensures the correct operation of the entire system. This is particularly important in installations powered by high-performance pumps or in systems with multiple take-off points.

It finds application in:

• central heating installations
• water supply and sewage systems
• industrial installations
• refrigeration systems
• fire protection installations
