Mini Drain Check

Mini Drain Check

The MDC is a check valve only that opens 2-5 PSI (.14-.35 BAR) below the nominal pressure rating. Available in 20 and 35 PSI (1.4-2.4 BAR) options. Ideal when a check feature only is needed or when it is necessary to operate sprinklers at different pressures that best suit environmental conditions. Perfect for overhead cooling of apples and other crops. The MDC prevents draining of the sytem in between frequent on / off cooling cycles.

6 Connection Options:

ELIMINATE CROP WASH OUT

Eliminate wash out and erosion damage caused by partially pressurized sprinklers during system start up and shut down.

EASILY CONNECTS
TO THE ROTATOR FAMILY

The Acme thread connects directly to Nelson Rotator Sprinklers (R5-R2000WF), the S10, D10, R10TG and to Nelson Feedtube assemblies.

EXTENDED PERFORMANCE
AND PRECISION ACCURACY

Precision components coupled with an internally lubricated o-ring minimize frictional drag and hysteresis.
