Slide Gate Valve
The Slide Gate Valve is designed for various gravity feed applications, including silos, hoppers, and screw conveyors. It effectively isolates materials, ensuring smooth operation in industrial settings.
Design and Functionality
A slide gate valve is essential for controlling fluid flow in pipelines. Its main components include:
When you turn the handwheel, the valve stem pushes the gate back and forth through a threaded mechanism. This motion controls the flow of materials, allowing for precise opening and closing.
Materials and Sealing
The sealing materials used in slide gate valves typically consist of hard alloys or polytetrafluoroethylene (PTFE). These materials resist high temperatures and corrosion, ensuring the valve’s stability and sealing performance over time.
