Dribble Control:
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.
