The L three-way ball valve type can only connect two pipes orthogonal to each other, and cannot maintain the connection of the third pipe interconnected at the same time, and only plays a d
Comparison of Pneumatic Control Valves and Hydraulic Valves
Pneumatic control valve refers to all kinds of pneumatic elements that control the pressure, flow and flow direction in the pneumatic system and ensure the normal operation of the pneumatic actuator or mechanism. The elements that control and regulate the compressed air pressure are known as pressure control valves. The element that changes and controls the direction of the air flow is called a directional control valve.
Working Principle and Advantages of Plastic Gate Valve
Working principle of the Plastic Gate Valve: the opening and closing part of the gate valve is the gate plate, the direction of motion of the gate plate is perpendicular to the fluid direction, the PVC Gate Valve can only be fully opened and closed, not adjusted and throttling. The gate has two sealing faces, the most commonly used two sealing faces of the mode gate valve form a wedge, wedge angles vary with the valve parameters, usually 5,2 52'when the medium temperature is not high. The gate plate of the wedge gate val
