H44T swing check valve

H44T swing check valve is a type of valve used to prevent medium backflow. It has a wide working pressure range and is suitable for various media, including water, oil, etc. The structural characteristics of this valve are significant. The valve disc can rotate around the pin axis outside the valve seat. When it is opened, the fluid pressure pushes the valve disc to rotate 90 ° and open, allowing the fluid to pass through the valve smoothly; When closed, fluid pressure or spring force causes the valve disc to rotate back to its original position, tightly contacting the sealing surface of the valve seat, achieving a good sealing effect. The store offers a wide variety of check valves, among which the spherical check valve (HQ41X) is made of ductile iron material, with a nominal diameter of DN40-DN600, suitable for media such as water and sewage, and has the function of preventing fluid backflow. It can also be customized. The valve has flexible connection forms, including flanges, grooves, etc. It is suitable for temperatures ≤ 80 ℃ and nominal pressures up to 1.0/1.6mpa, which can meet the needs of different industrial applications.

H44T rotary check valve is suitable for pipelines of water and steam media with working temperature ≤ 100 ℃, and is used for one-way opening and closing to prevent medium backflow.

structural characteristics
