An improved pneumatic jetting valve includes a housing with first and second chambers. A pneumatic piston is enclosed between the chambers. First and second solenoid valves are configured to respectively supply air pressure to the chambers and to exhaust the chambers. A controller is operable to regulate the pressurization and venting of the chambers. The controller controls the timing of control signals for the first and second solenoid valves to control the overlap time during which both the first and second chambers are pressurized. By controlling this overlap time, the controller controls the speed of the drive pin of the jetting valve and thereby the speed at which the valve closes to jet a droplet of material.

A fluid dispensing apparatus is disclosed. Systems include an in-line or linear bladder apparatus configured to expand to collect a charge of fluid, and contract to assist with fluid delivery and dispensing. During a dispense-off period process fluid can collect in this bladder after the process fluid is pushed through a fine filter (micro filter). A given filtration rate can be less than a dispense rate and thus the system herein compensates for filter-lag that often accompanies fluid filtering for microfabrication, while providing a generally linear configuration that reduces chances for defect creation. 1.
