Midwest Control MCDV50-S 1/2 Condensate Timer Drain w/BPS Strainer 115V 230 PSI

Key Facts

• Timer-controlled condensate drain for compressed air systems, with 115V operation and a 230 PSI pressure rating.
• Includes a BPS strainer with a shut-off valve for strainer maintenance.
• 1/2" FNPT inlet and outlet connections.
• Adjustable interval and discharge times for setting the drain cycle.

Overview

The Midwest Control MCDV50-S is a 1/2" automatic condensate timer drain used to discharge accumulated moisture from compressed air systems. It is suitable for air receivers, filters, dryers, separators, and drip legs.

This configuration includes a BPS strainer. Its shut-off valve allows the strainer screen to be cleaned without loss of air pressure in the tank or drain.

Features

• Solid-state timer controls the interval between drain cycles and how long the valve opens.
• Included BPS strainer helps keep debris from reaching the drain valve.
• Strainer shut-off valve provides access for screen cleaning.
• Manual test switch allows an on-demand operation check.
• Yellow LEDs indicate on and off status.
• Can be mounted in any position.

Category FAQs

Q: What is the difference between MCDV50 and MCDV50-S? A: The MCDV50-S includes a BPS strainer. Midwest Control does not list a strainer as included with the standard MCDV50.

Q: Is the BPS strainer a self-cleaning valve kit? A: No. Midwest Control lists the separate MCDV50-DK with a BABC self-cleaning drain kit.

Q: Can the strainer screen be cleaned without depressurizing the tank? A: Midwest Control states that the BPS strainer's shut-off design allows screen cleaning without loss of air pressure in the tank or drain.

Q: Can I test the drain without waiting for the next timed cycle? A: Yes. The MCDV50-S has a manual test switch.
