The MRDC ensures high uniformity and even flow throughout your system by eliminating pressure variation from uneven topography or friction loss. The drain check feature eliminates sprinkler drizzle during shut down and start up.
The MRDC (mini regulator-drain check) combines the features of the MR (mini regulator) with those of the MDC (mini drain check).
Choose from the following nominal regulated pressures:
Always maintain an inlet pressure of at least 5 psi more than the nominal pressure rating.
