EVR Selector Guide
Electric variable ratio (EVR™) metering enables manufacturers to mix, meter and dispense two-component (2K) sealants and adhesives using the same equipment.
Identify the ideal setup for your material and production requirements in three steps.
These base systems are meant to cover the most common applications you may need. This includes:
- The electric motors to power the system’s pumps
- A transformer of 480volt is needed
- Stainless steel inlet and outlet fittings with pressure transducers
- Communications Gateway Module (CGM) options for either Ethernet/IP or PROFINET
Note: These base systems DO NOT include the Z-Pumps. These must be selected separately and installed after delivery.

Base EVR System | Voltage | Communication Gateway Module | PN | Select only 1 |

Add Inlet Regulator Kit
Optional Feature.
It is recommended that you install regulators on the inlets of your Z-Pumps for consistent operation changing environments and material conditions.

EVR Mastic Inlet Regulator Stainless Steel | 26A704 | |
EVR Mastic Inlet Regulator Carbon Steel | 26A705 |
The Z-Pumps will be selected according to the volumetric ratio, which can be adjusted on the EVR with up to a 5:1 multiplier.
For instance, if you select 40cc and 80cc pumps, this results in a 2:1 ratio, allowing you to run the machine from 1:1 up to 10:1. To achieve an even broader ratio, select pumps with a wider volumetric ratio.
To achieve a 50:1 ratio for boosted urethanes, use 160cc and 10cc pumps, then enter 3.13:1 on the display. 160/10 = 16:1 ratio x 3.13 = 50:1.

The dispensing valve you choose depends on your material and application needs.
A) The MD2 Valve is the most common choice for 2K sealants and adhesives, featuring a single acting opening/closing mechanism and offering different ratio ranges for specialty coatings.
B) The TC Valve allows for 2K dispensing and individual control of each component, enabling base purging of static mixers.
C) The MD-X Valve is the highest flowing 2K valve, capable of exceeding a flow rate of 75cc/sec.
Some of the below accessories are required for certain valves, while other optional accessories are used in complex applications and when dispensing difficult materials.
A) MD2 valve for static mixing and recirculation as an option.

The recirculation kits are most often used when there are suspended fillers in a low-viscosity material. By recirculating these, the fillers are prevented from settling out of the material.
