Radially operated pneumatic valve has two half-sections with rotation against each other to set the air flow from a pump ball to a double-action pneumatic cylinder for a stepped movement or blocking action

摘要

The radially operated pneumatic 4/2 path control valve, especially for the operation of a double action pneumatic cylinder using a pump ball, has two axial half-valve sections (1,2) which, when rotated against each other by 180 deg , activate three switch settings. The pump ball (4), with a non-return valve (15), is connected directly to the valve to deliver air pressure by manual energy. The valve is linked to the pneumatic cylinder to give a stepped movement or blocking action.
