The MRDC (mini regulator-drain check) combines the features of the MR (mini regulator) with those of the MDC (mini drain check).
- Eliminate sprinkler drizzle during system start up and shut down.
- Reduces a high inlet pressure to a constant outlet pressure.
- Ideal for use with 1/2" Acme threaded Rotator Sprinklers, especially the R2000WF.
- 0.15-5 gpm (34-1135 lph)
Choose from the following nominal regulated pressures:
- 20 psi (1.4 bar) / 30 psi (2.1 bar) / 35 psi (2.4 bar) / 40 psi (2.8 bar) / 45 psi (3.1 bar) / 50 psi (3.4 bar) / 60 psi (4.1 bar)
Always maintain an inlet pressure of at least 5 psi more than the nominal pressure rating.

Sprinkler performance data have been obtained under ideal test conditions and may be adversely affected by wind, poor hydraulic entrance conditions, or other factors. Published radius and diameter of throw performance are at nozzle pressure when tested at 1,250 feet above sea level. Your results may differ from the test data results obtained by Nelson Irrigation Corporation and Nelson Irrigation Corporation makes no representation regarding droplet conditions, uniformity, application rate, or fitness for a particular purpose.
