THREE-WAY TWO-POSITION SPOOL-TYPE PALM-BUTTON-OPERATED PNEUMATIC DIRECTIONAL VALVE MECHANISM

Cliquez pour agrandirCliquez pour agrandir Description

Compressed air is supplied from the main to port 1, and port 2, the outlet port of the valve, is connected to the atmosphere through port 3. When palm button 4 is pressed, spool 5 is pushed downward, overcoming the resistance of spring 6. In its downward motion, lower packing cup 7 of the spool passes a row of radial ports 8, disconnecting them from port 3 and the atmosphere. Air from port 1 passes through a row of radial ports 9 into outlet port 2. When palm button 4 is released, spool 5 is returned by spring 6 to the position shown. The valve can be used as a two-way valve if a plug is screwed into port 3.
