ARO 637541-3-H Solenoid Valve Block Kit, 1" Black Polypropylene
1" PD-to-PE conversion kit: black polypropylene block, coil rated 24 VDC ATEX/IECEx.
Black polypropylene valve block with a 24 VDC ATEX/IECEx solenoid coil. It turns a PD-configured 1" ARO EXP or Compact pump into a PE unit.
The ARO 637541-3-H is the black polypropylene version of the solenoid valve block kit for 1-inch ARO pumps. It is sold as a conversion kit that takes a 1" Compact or EXP series pump from its PD setup to PE. A solenoid valve uses an electric coil to direct air, so the pump strokes in response to an electrical signal instead of shifting on its own.
This variant carries a 24 VDC coil listed as ATEX/IECEx. That coil, together with the black polypropylene body, is what sets it apart from other 1" kits in the 637541 range.
When to Use This Kit
- Your process control system needs to start, stop or pace a 1" pump with a 24 VDC signal.
- The pump sits in an area where your site specifies ATEX/IECEx rated electrical parts.
- You are upgrading a PD pump already in service instead of replacing the whole unit.
No pump list is attached to this kit. Before ordering, note the model and serial number from the pump nameplate and check them in the ARO Electronic Interface Accessories document for 1" pumps.
