Compatible Systems and Controls

Electric Fixed Ratio (EFR) System

Easily integrate the EFR with the Voltex Dynamic Mix Valve for

a complete two-component meter, mix and dispense solution.

The EFR is ideal for applications requiring precision dispense

and superior control over sealant materials.

PR70

When coupled with the Voltex Dynamic Mix Valve and control

box, the ADM equipped PR70 accurately meters, mixes and

dispenses two-component medium to low-viscosity materials

for potting, gasketing, sealing, and encapsulation applications.

Hydraulic Fixed Ratio (HFR) System

A meter, mix and dispense system for materials ranging from

epoxies to elastomers. Compatible with Voltex Dynamic Mix

Valve and ADM control box for high throughput applications

requiring on-ratio dispensing, precision dispense, and

consistent material flow.

Process Controls

An Easy to Use Control Module

With the Voltex Dynamic Mix Valve and controls, you can be confident that

you’re accurately dispensing material every time. Quickly optimize your

process with RPM and ramp up settings.

Simple Diagnostics

The controls also incorporate simple diagnostic screens which allow you to

quickly check all the process variables and define predictive maintenance

parameters.
