Check valve 3/4 inch with flap, PN16 ZZK2W

Check valve with flap, designed to protect water and heating systems against backflow. Made of high-quality brass, resistant to corrosion and mechanical damage. Ideal for both new installations and modernization of existing ones.

This model, with a 3/4 inch connection, is characterized by reliable operation and simple installation. The valve flap ensures a tight seal, minimizing the risk of leaks and energy losses. NBR sealing guarantees long-term tightness even in difficult working conditions.

• Application: This valve is dedicated to protecting pumps, hot water tanks, boilers and other hydraulic devices against backflow of the medium. The body is made of CW617N brass (Nickel Free), which means no nickel in contact with water – important for maintaining the quality of drinking water. The use of this type of brass ensures durability and corrosion resistance. The NBR seal is resistant to water and glycol, providing long-term tightness and performs well in a wide temperature range. The valve operates at a temperature of up to 100°C, allowing use in central heating installations where the temperature may be elevated. The maximum working pressure is 16 bar, ensuring safe operation in standard water and heating installations and resistance to high pressure. The connection is a 3/4 inch tapered internal thread (NPT) - a standard solution that facilitates installation and is compatible with most available installation elements.

The Ferro ZZK2W check valve is a solid and durable solution for professionals and demanding users. Its precise workmanship and high-quality materials guarantee trouble-free operation for a long time. Installation is intuitive and does not require specialized tools, which translates into saving time and installation costs. Additionally, the presence of a barcode on the packaging facilitates product identification and inventory management in wholesale and installation stores.
