2 TECHNICAL DESCRIPTION
2.1 Valve operation
The DAV 150 volumetric dispensing valve is a pneumatically operated component designed for precision dispensing of low
viscosity lubricants.
The exchange of the pneumatic supply, at a pressure equal to or greater than 6 bar, will lead to the emptying of the volumetric
chamber and the relative outflow of a constant and adjustable quantity of fluid.
