Mini Pressure Regulators

The MRDC (Mini Regulator-Drain Check)

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.
• 34-1135 lph (0.15-5 gpm)

Choose from the following nominal regulated pressures:

1.4 bar (20 psi) / 2.1 bar (30 psi) / 2.4 bar (35 psi) / 2.8 bar (40 psi) / 3.1 bar (45 psi) / 3.4 bar (50 psi) / 4.1 bar (60 psi)

Always maintain an inlet pressure of at least 5 psi more than the nominal pressure rating.

MRDC – 1/2″ Acme Threads

• 1/2″ Female Acme x 1/2″ Male Acme
• 1/2″ FNPT x 1/2″ Male Acme

MRDC – NPT Threads

• 1/2” FNPT x 1/2″ MNPT

The MR (Mini Regulator)

Ensure high uniformity and even flow throughout your system and eliminate the effects of pressure variations due to uneven topography or friction loss.

• Reduces a high inlet pressure to a constant outlet pressure.
• Ideal for use with 1/2″ Acme threaded Rotator Sprinklers.
• 34-1135 lph (0.15-5 gpm)

Choose from the following nominal regulated pressures:

1.4 bar (20 psi) / 2.1 bar (30 psi) / 2.4 bar (35 psi) / 2.8 bar (40 psi) / 3.1 bar (45 psi) / 3.4 bar (50 psi) / 4.1 bar (60 psi)

Always maintain an inlet pressure of at least 5 psi more than the nominal pressure rating.

MR – 1/2″ Acme Threads

• 1/2″ Female Acme x 1/2″ Male Acme
• 1/2″ FNPT x 1/2″ Male Acme

MR – NPT Threads

• 1/2″ FNPT x 1/2″ MNPT

The MDC (Mini Drain Check)

The MDC is a check valve only that opens .14-.35 bar (2-5 psi) below the nominal pressure rating. Available in 1.4 / 2.4 bar (20 and 35 psi) options.

Applications

• Use in conjunction with R2000WF Rotator Sprinklers on high value vegetables to prevent washout of delicate seedbeds during system start up and shut down.
• Prevent drain down and puddling of hanging (inverted) sprinkler systems in indoor nurseries and riding arenas.
