Material pressure regulator
Perfectly constant material flow
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:
- MPR with piston
This type of material pressure regulator is especially suitable for the processing of selflubricating 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.
- 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 tungste n carbide, also abrasive media, such as, epoxy resins, polyurethanes and many other materials. The sealing of the spring space takes place via the membrane.
