Brass check valve is an essential device in a hydraulic installation to prevent backflow of water and damage to your pump. Its main function is to block the return and regulate the flows in one direction of circulation. The valve body is equipped with a spring-loaded piston, which will automatically close your system and leave a large flow in the open position. This check valve is designed for both professional and domestic use. It can be used in commercial premises, industry, plumbing, heating, irrigation, water supply and distribution networks, etc. It is characterized by allowing its mounting in both horizontal, vertical and diagonal positions. In vertical and diagonal positions the flow direction must always be upwards. The indicator arrow on the valve will show you the flow direction. Lightweight check valve with plastic shutter. Reinforced body made of CW617N brass, NBR seal and threads according to ISO 228/1 (DIN 259). Being made of brass, this product is highly resistant to mechanical damage and corrosion as well as high temperatures. Therefore, it will serve you well for a long time without failing. The check valve withstands a working temperature of 0 to 80° and is especially indicated for cold water. Package list: 1 Check valve. Nominal pressure: 16 bar. Material: made of brass - durable material, can be used several times and serve for a long time. Respect the flow direction indicated on the body by the arrow. It is a practical and reliable solution to ensure good water circulation of a pressure check system, which always gives you the expected and permanent result.
