Material Pressure Regulators MDR

Icon Pfeil nach unten zum Ausklappen der Sprach-Auswahl

The Material Pressure Regulator MDR-LW04 is used to reduce pressures and to minimise the pulsation which occurs when material is conveyed using piston pumps.

The working pressure can be adjusted continuously from 5-50 bar with the preload screw and fixed with the lock nut. The ratio between the inlet and outlet pressure should ideally not exceed 5:1.

ABNOX Material Pressure Regulators are designed for handling self-lubricating media such as grease and oil.

The Regulator can be ordered with an Outlet Pressure Gauge (1M) or with Inlet and Outlet Pressure Gauges (2M).

In addition to these two standard products, ABNOX also offers the version with an Inlet Pressure Gauge (1M) and an Electrical Pressure Switch with Display (1DS).

All Material Pressure Regulator models are optionally also available with a Mounting Set for direct installation on ABNOX Grease Pumps (Z-Adapter) or at the individual Systems (Connecting Plate).
