FAQs About Pneumatic Shut-Off Valve
Q1: What is a pneumatic shut-off valve used for?
A: A pneumatic shut-off valve is used to quickly start or stop bulk material flow in pneumatic conveying systems, silos, and discharge lines. It is widely applied in cement, fly ash, clinker, and powder handling operations where reliable on/off control is required.
Q2: What is the difference between a pneumatic shut-off valve and a flow control valve?
A: A pneumatic shut-off valve is designed for on/off isolation, while a flow control valve is used for modulating and regulating material flow rate. Shut-off valves focus on sealing performance and fast response rather than precision dosing.
Q3: Can pneumatic shut-off valves handle abrasive materials?
A: Yes. Pneumatic shut-off valves can be equipped with wear-resistant liners and reinforced sealing structures, making them suitable for abrasive materials such as cement, fly ash, limestone powder, and clinker.
Q4: Are pneumatic shut-off valves suitable for continuous operation?
A: Yes. When properly selected and maintained, pneumatic shut-off valves support continuous or intermittent operation in industrial bulk material handling systems with stable sealing performance.
