Hand Valve/Ball Valve MGL3974

Product Overview

The hand valve/ball valve is a quick-connect component designed specifically for pneumatic systems. It is primarily used to rapidly connect PU/PE/PA pneumatic hoses to valve bodies, cylinders, air supply lines, and other components. Relying on a mechanical snap-lock structure, it enables tool-free, quick insertion and removal of hoses, offering convenient and efficient operation. The product features a brass body with nickel plating as the main material, equipped internally with stainless steel retaining rings and NBR nitrile rubber sealing rings. For certain special applications requiring high temperature and oil resistance, an FKM fluororubber sealing version is available. This product can meet the usage requirements of most pneumatic circuits and is widely applied in pneumatic systems across various fields, including automation equipment, textile machinery, packaging equipment, and construction machinery.

Core Structure and Operating Principle

This hand valve/ball valve adopts a dual-sealing structure. A stainless steel retaining ring clamps the outer wall of the hose, working in conjunction with an O-ring to provide double sealing. This ensures a secure connection while effectively preventing air leaks. When inserting the pneumatic hose, the stainless steel retaining ring automatically locks onto the hose’s outer surface, achieving a “plug-and-lock” effect without any tools, making installation simple and fast. To remove the hose, simply press the snap-lock mechanism on the connector, allowing easy extraction—ideal for line debugging and equipment maintenance. This structural design not only enhances assembly efficiency but also reduces human error, ensuring consistent pneumatic circuit assembly.
