Two-Stage “Dribble Control” Package
Ideal Solution for Dribble Control
The Moniteur DSS Two Stage Package is a
complete unit incorporating two solenoid valves and
specially configured limit switches designed for twostage operation. The package mounts to most rotary
pneumatic actuators and allows users to transform
an automated valve into a two stage shutoff
package. The most common applications are:
Valve #2
(2 Way)
> Filling or metering vessels. By being able to
reduce the flow rate at a given point during a
filling operation, it is possible to more accurately
and efficiently fill a vessel.
Valve #1
(3 Way)
Exhaust
Filter
> Flow dampening. With the two stage package,
valves can be partially closed and then
completely closed later. This dramatically
reduces shock to pipes and valves due to water
hammer.
Requirements
> Two voltage sources to power both solenoid valves (#1 and #2).
> Contact logic (2), which may be provided by flow meters, scales, level sensors, or PLCs
> Spring return pneumatic actuator with a clean air source
Features
> Dual flow positions for filling vessels or flow dampening
> Fully adjustable set points allow the user flexibility to determine proper stage switching
> Open / Closed limit switches provide additional valve end point monitoring
> Factory assembled and tested, saving users and assemblers time and money

Installation Procedure / Sequence of Operation
Warning:
Be sure voltage and air pressure supplied match solenoid specifications.
1. Mount limit switch package to the rotary actuator with an appropriate mounting bracket.
2. Connect power and clean filtered air to proper connections (see table on other side for standard
valves). Ensure that all air connections are tight and all electrical connections are secured at their
proper terminal points.
3. With no power to V-1 and V-2, the valve should be in the fully closed position (sequence #1)
4. Energize V-1 and V-2 (sequence #2), solenoid #1 (sol1) will energize allowing the air pressure to
rotate the valve/actuator package to the fully open position.
5. De-energize V-1 and the package will rotate in the opposite direction until the white cam trips switch
3 (blue) and energizes solenoid #2 (sol2). This will stop the valve rotation at the set mid position.
If the mid position is incorrect, estimate approximately how many degrees of rotation the cam
needs to be adjusted. CAUTION - do not adjust cam until the unit is in the fully closed position, as
the unit might rotate unexpectantly if the cam is adjusted under power.
6. Finally, de-energize V-2 (both V-1 and V-2 will be de-energized) and solenoid #2 (sol2) will Deenergize and the valve/actuator package will rotate to the fully closed position. One full cycle has
just been completed. If the mid set position requires adjustment, adjust the package now.
7. Repeat steps 4-6 to verify adjustment and/or re-adjust dribble position.
Caution:
Do not adjust cams while cycling system as the unit might shift unexpectantly
