The DLR-44 Nutech-01 series regulator is a piston sensed, dome loaded, positive biased, pressure regulator. The positive bias provide a constant outlet pressure from 50-1500 PSI (3.4-105 BAR) greater than the reference pressure. Due to the self-vented feature, the outlet pressure can be vented through the regulator allowing downstream regulation even with a decreasing reference pressure. The DLR-44 Nutech-01 provides valve. A segregated vent allows the outlet pressure to be vented separately and eliminates mixing media with the reference pressure zone.

Valve Function

Inlet pressure acta upward on small balancing diaphragm (or piston in 21/2-3" sizes) to equalize downward pressure on valve disc, providing fully balanced action. Inlet pressure variations are equalized without affecting set-point. When the adjusting spring is compressed, it opens the main valve to admit fluid to down stream side. When the downstream pressure under the large diaphragm equals the force exerted by the adjusting spring, equilibrium is restored and the main valve maintains flow of the set down stream pressure. Simply designed, your Nu-Tech hi-flow is slated for a long, trouble-free life. Standard renewable parts never need special fitting or machining. Here's a rugged regulator built to absorb hydraulic system shocks that upset ordinary valves.
