ARO 637543-4-D White Polypropylene Solenoid Valve Block Kit, 2"/3"
White polypropylene solenoid valve block kit with 24 VDC coil, made for the 2" and 3" Compact/EXP lineup.
ARO 637543-4-D is the white polypropylene valve block kit, specified with a 24 VDC coil, for PD to PE conversion on 2"/3" Compact and EXP units.
White polypropylene is what sets the ARO 637543-4-D apart. This solenoid valve block kit covers ARO's 2" and 3" Compact and EXP units and is listed by ARO as their PD to PE conversion kit. The coil is a standard 24 VDC type.
Fitted to the pump, the block takes over air switching. A 24 VDC signal from your controls tells it when to send air to the pump, so the pump can follow an automated schedule rather than run continuously.
Reasons to Choose It
- You want the block in white polypropylene, not black or aluminum.
- A 2" or 3" pump needs to respond to a control signal.
- Your system supplies 24 VDC and has no hazardous-area coil requirement listed.
Fit Guidance
This kit has no pump fit records attached. Locate the nameplate, note the pump model and serial, and verify them in the ARO parts list. More detail sits in the Process Ready Pumps material from ARO.
