The Moniteur DSS Dribble Control Package is a complete product incorporating two reliable ASCO solenoid valves and specially configured limit switches designed for two-stage operation. The package mounts to most spring return rotary pneumatic actuators and allows users to transform an automated valve into a two stage shutoff package. The most common applications are: Filling or metering vessels. By being able to reduce the flow rate at a given point during a filling operation, one can more accurately fill a vessel.

Flow dampening. With the two stage package, valves can be partially closed rapidly and then completely closed gradually. This reduces water hammer and shock to pipes and valves. 

Application Note - Using spring return actuators for dribble control allows the unit to fail-close in case of an air or control signal failure. Avoid dribble control packages that use double acting actuators - they cannot provide this feature. Moniteur will not supply product so configured.
