China Full-bore Butterfly Valve Manufacturers, Suppliers, Factory

Welcome to this detailed guide on check valves, brought to you by Milestone—a trusted name in industrial valve manufacturing for over two decades. In this article, we will explore the fundamental aspects of check valves, including their definition, working principles, types, applications, and key benefits. Additionally, we will provide an in-depth look at Milestone’s high-performance check valve products, complete with detailed technical specifications presented in lists and tables for clarity and precision.

2.The valve is not selected according to the working conditions, and the cut-off valve is used as a throttle valve, resulting in excessive closing specific pressure and closing too fast or not tightly, causing the sealing surface to be eroded and worn.

​Large butterfly valves provide critical advantages over other types of valves in many applications. The valve's simple design ensures low maintenance cost and easy installation.

The swing check valve has a pin structure and a gate like disc resting freely against the sloping seat surface. In order to ensure that the valve disc can reach the proper position of the seat surface every time, the valve disc is set in the pin structure, so that the valve disc has enough swing space, and makes the valve disc truly and well contact with the seat. When the swing check valve is fully opened, the fluid pressure is almost unimpeded, so the pressure drop through the valve will be smaller. The valve disc can be made of metal, or inlaid with leather, rubber or composite cover, depending on the requirements of the applicable function.

Quality control of the main body blank. All parts of this valve are forgings. During forging, they are strictly carried out in accordance with the forging process regulations and process cards. The initial forging temperature, final forging temperature, deformation degree and deformation speed are strictly controlled.

​In the world of fluid control, the selection of the right valve is essential to ensure efficiency, safety, and long-term reliability. Among the various valve types, the Wafer Type Butterfly Valve stands out for its compact design, easy installation, and cost-effectiveness. This valve has been widely adopted in industries ranging from water treatment and power generation to petrochemicals and food processing.
