Dribble Control VPT
General Purpose Nema 4, 4X
or Explosion-Proof Nema 4, 4X, 7 & 9
General Purpose
Intrinsically Safe ia
• 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.
Approvals
Explosion-proof Version :
UL / CSA Approved for Class 1, Division 1 Groups C-D and
Class 2, Division 1 Groups E, F, G with Mechanical SPDT switches.
Features & Benefits
Dual flow rate 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
All of the standard features of our Sentinel or Watchman product lines.
Moniteur Switch and Sensor Selection Guide
Mechanical SPDT and DPDT Switches
The most popular switch for general purpose applications is rated 15A at 120 VAC and 2.5V at 24 VDC. Our standard mechanical switches are specified with higher operating forces and offer better resistance to freeze up. Gold Plated SPDT switches rated at 1A at 24 VDC are a low-cost alternative for intrinsically safe applications. DPDT Mechanical Switches rated at 10A / 125 VAC and 7A / 24VDC are also available.
