Product Questions & Answers

Got a DGMDC-3-Y-PM-41 going on a manifold block. what kind of bolts do we need and how tight should they be?

Question by: Randy O on Dec 20, 2025, 11:42 AM

Fasten these units using 10-24 grade 8 socket head cap screws. You will want to lubricate the threads and torque them down to somewhere between 63 and 80 inch pounds for proper seating.

Trying to swap out a stack valve, is this one the D03 SystemStak check in P with free flow toward the work port, and is it the 41 design?

Question by: Frank W on May 9, 2025, 8:51 AM

For replacement matching, the identifiers on this valve are DGMDC-3-Y-PM-41 (41 design) and catalog number C1JL49. Function-wise it is a check in P with free flow toward the work port, and it is an NFPA-D03 size SystemStak style valve.

i’m trying to stop oil from sneakin back the wrong way. which direction does this D03 SystemStak check valve let flow go?

Question by: Rusty C on Mar 4, 2026, 2:16 PM

Function-wise, it allows free flow toward the work port when the check is in the P line, and it blocks flow in the opposite direction.
