I. Basic Structure and Working PrincipleRising Stem Gate ValvesStructural Features: For rising stem gate valves, the stem nut is fixed on the valve body or the valve bonnet. During the opening or closing process of the gate valve, the stem will move up and down along with the rotation of the stem nu

Understanding Wedge Gate ValvesWedge gate valves are a type of gate valve that uses a wedge-shaped gate to control the flow of fluid. The wedge design allows the gate to seal tightly against the valve seats, providing a reliable shutoff mechanism. These valves are available in various materials and

Understanding Swing Check ValvesSwing check valves operate by allowing fluid to flow freely in one direction while automatically closing to prevent backflow when the flow direction reverses. The valve's disc swings on a hinge or trunnion, aligning with the flow direction when open and sealing agains
