An air-actuated two-way plug valve is a valve that controls fluid flow by rotating a plug driven by a cylinder. It features a unique design, allowing for easy installation and operation in limited spaces, with the added benefits of simplicity and versatility. The air-actuated two-way plug valve is widely used in various industries such as metallurgy, mining, building materials, grain, and chemicals, particularly in scenarios where flow control changes or quick cutoffs are required.
Working Principle and Structural Features
Pneumatic双向 plug valves are driven by cylinders to rotate the plug, controlling the fluid flow. They feature a compact structure, tight component fit, and a small size, saving space. The valve assembly includes a frame, gate plate, screw, nut, handwheel, and other parts, offering manual, electric, and pneumatic drive options to meet various operating conditions and control requirements.
Application Scenario
Pneumatic double-plate valves play a crucial role in various industries such as metallurgy, mining, construction materials, grain, and chemicals. They are particularly suitable for controlling the flow or conveyance of powdery, granular, particle, and small piece materials, widely used in industries like mining and grain to regulate flow changes or quickly cut off. For instance, in the metallurgy industry, these valves can be used to control the flow and conveyance of solid materials; in the grain industry, they can be used to control the flow and cutoff of granular materials.
Material and Performance Parameters
The material of pneumatic two-way plug valves includes carbon steel and stainless steel, and customized non-standard spiral gates can be provided according to customer requirements. They offer a wide range of nominal bore sizes and stable nominal pressures, made of cast steel or stainless steel to ensure durability and stability. Additionally, pneumatic plug valves must undergo rigorous testing before shipment, including shell tests and sealing tests, to guarantee their performance and quality.
