The opening and closing parts of the wedge gate valve are the gate, the direction of motion of the gate is perpendicular to the fluid direction. The wedge gate valve can only be fully opened and fully closed and can not be adjusted and throttled. The gate has two sealing surfaces, the two sealing faces … Read more
The double block and bleed valve is abbreviated to DBB valve. It is made up of two ordinary ball valves linked by a common inlet end. The double block and bleed ball valve is a product intended to substitute several connections between conventional valves; as the name suggests, it is a double block and bleed … Read more
The top entry ball valves are the valves that assemble the ball from the top end. It’s quite similar to a globe valve that has a body and a cap, except that the trim portion uses a ball type. It consists of a single entity. Typically, the top entry ball valves are made of cast metal. Since … Read more
Valves can be used to control the flow of all kinds of fluids such as air, mud, oil, water, steam, liquid metals, corrosive mediums, and radioactive mediums. Therefore, it is very important to choose the most suitable valves for the piping system. To choose the most suitable valve for the piping system it is important … Read more
Lubricated plug valve can be divided into conventional lubricated plug valves and pressure balanced plug valves. The special grease is injected from the top of the plug body between the valve cone hole and the plug body, forming an oil film to reduce the valve opening and closing torque, increase sealing and service life. The … Read more
Dual Plate Check Valves are automatic mechanical valves, which open with a forward flow and shut to a reversal inflow. The key feature of the check valve is to secure the mechanical devices in the pipe system by avoiding the reversing of the fluid. The swing check valve is an economic kind of check valve, but it has a … Read more
A Swing Check Valve is desinged to prevent the medium in the pipeline from flowing back. As pressure reaches zero, the valve shuts fully to prevent backflow. Swing check valves belong to the group of automatic valves, which are used mostly in pipelines where the medium flows in one direction and allow only the … Read more
