DOPAG material pressure regulators are used to reduce the feed pressure down to the required operating pressure. As well as accurately regulating material pressure, these valves will also compensate for pulsations that occur as a result of the reciprocating action of piston pumps. Pulsations cause a brief decrease in pressure that could lead to a slight reduction in the flow of material. These regulators can be used on materials with viscosities from 5,000 to 500,000 MPa s. DOPAG material pressure regulators are manufactured with two different types of construction:
1. MPR with piston
-> This type of material pressure regulator is especially suitable for the processing of self-lubricating materials such as greases and oils as well as single and plural component silicones. The sealing of the spring space takes place via a slide ring seal.
2. MPR with membrane
-> This type of material pressure regulator is most suitable for use with reactive, moisture sensitive and because the ball and seat are manufactured from tungsten carbide, also abrasive media, such as epoxy resins, polyurethanes, and many other materials. The sealing of the spring space takes place via the membrane.
DOPAG micro flow sensor is a real-time flow monitoring component.
The Micro-Flow Sensor is a flow detecting device, used within a semi or fully automated metering process, to detect whether the material has been dispensed. The Micro-Flow Sensor does not control the metering volume.
It is used particularly when handling unfilled grease with NLGI class 1 to 3, high viscosity oils or silicone-oils. The Micro-Flow Sensor can be adapted to the DOPAG Micro and Mini metering valves as well as to the 419 range of metering valves.

Fast and accurate dosing of low to high viscosity media.
Needle metering valves are used for the processing of low to high viscosity media. The valve consists of two separate parts. This means that it is not possible for any leaking material to enter the actuating air cylinder, which could cause a malfunction. The needle is sealed by means of an adjustable packing set (Metering volume: 0.001 - 3.0 cm3).

A compact, versatile and reliable DOPAG system for precise dosing of 2K media.
The eldomix 100/600 range of systems are compact, solvent-free, gear pump driven metering and mixing systems. They are used to apply low to medium viscosity multiple component materials such as epoxies, polyurethanes, and silicones. The material is supplied from pressure vessels. Special configurations to process high viscosity media are also available.
Metered application of fluids is increasingly becoming part of automated manufacturing processes. As a result, no dosing unit concept would be complete without the integration of all the necessary procedures for the pre and after treatment of components, quality assurance measures and conveying and handling technology. As a dosing technology producer and designer of customized solutions for automated gluing, sealing and potting, DOPAG is a place that offers the full package from a single source. Only a system that is precisely tailored to the application requirements ensures a smooth production and contributes to overall business success.
Modis is a highly dynamic, speed-proportional metering system for controlling the flow rate of single component adhesive applications in the automotive industry, as well as in the automotive supply industry. Modis allows operators the opportunity to cover a wide range of flow rates with just four different construction sizes.
Coredis is used for the processing of special low-density 1K epoxies filled with micro hollow spheres. The unique challenge, in this case, is that we are dealing with a reactive medium which remains in the material contacting systems after processing and could be subjected to a curing reaction. In order to prevent this, coredis features a specially developed structure. The material is supplied directly from the delivery container and the metering is carried out by means of a gear pump mounted on a heated follower plate. The material is guided through the connected heater hose to the dispensing nozzle which continuously fills the core filler into the honeycombs.
Clean and reliable feeding of oils, grease, and adhesives
DOPAG drum pumps have proved themselves to be particularly useful as central material supply systems as well as being able to supply single stations. They feed viscous materials such as grease, adhesives, and sealants or the base components of silicone, polyurethane and epoxy resin directly from original containers.
The range of DOPAG grease pumps is designed to feed all types of greases from open-topped containers between one liter and 200 liters in capacity, cleanly and directly from the original containers. Each grease pump is mounted onto a twin post ram arrangement and is fitted with a follower plate that fits snugly inside the material drum, making certain that the grease cannot become contaminated during use. The follower plate also has the effect of wiping the sides of the drum clean that leads to minimal waste grease. DOPAG grease pumps have proved themselves particularly useful as central material supply for multiple grease metering systems as well as being able to supply single stations. The grease pumps may be arranged in pairs with an automatic changeover system to ensure that production is not lost when a drum of grease becomes exhausted.
Vectodis is used to handle single component materials. Just a suitable material supply and the metering computer is required. The modular construction of vectodis enables a wide range of use. This product line is especially recommended if material needs to be applied in high precision and repeatable way. The material can be processed by either shot dispensing or continuous flow.
dynamicLine: gasketing, bonding, sealing, potting, automation
DOPAG is the system provider for gasketing, bonding, sealing, potting, and automating. The dynamicLine is based on the newly developed dynamic mixing head with its innovative valve technology. With this technology, DOPAG has raised the bar and set a new benchmark regarding ease of use, accuracy, and
reliability for dynamic mixing.
The high-performance mixing head is based on 40 years of experience with two-component low-pressure metering and impresses with its unique valve technology with a booster. Functions such as the rinsing of the mixing system with water (alternatively cleaning agent), the controlled opening and closing of the mixing system, and the extremely precise metering performance set new standards on the market.
DOPAG drum pumps are chop check pumps. They feed single component materials such as adhesives, sealing compounds, polyurethane, silicone etc. with viscosities up to 5.0 million mPa s directly from original containers.

Volumetric flow meters monitor the volume flow of liquids based on the gear principle. The measuring unit is constructed for highest accuracy with precisely fitted gears. The rotation of the measuring unit is precisely detected by a contactless signal sensor system and then converted into digital signals.
In the sections in which they are completely enclosed by the housing walls, the tooth gaps of the measuring unit gears form measuring unit chambers which digitalize the flow depending on their chamber volume.
