ARO 637543-4-F Solenoid Valve Block Kit, 2" & 3" White Polypropylene
White polypropylene PD to PE solenoid valve block kit, 24 VDC NEC/CEC, for 2" & 3" Compact and EXP pumps
Kit 637543-4-F switches 2" and 3" ARO Compact or EXP pumps over to PE control. It uses a white polypropylene block and a 24 VDC NEC/CEC coil.
ARO 637543-4-F serves the larger end of the range: 2" and 3" Compact and EXP series pumps. The kit converts a PD model to PE control with a solenoid valve block made of white polypropylene. Coil voltage in the spec table reads 24 VDC NEC/CEC.
With the block in place, each pump stroke follows an electrical signal. Operators can then pace or pause the pump from a control panel instead of adjusting air by hand. ARO's Electronic Interface Accessories and Process Ready Pumps publications both reference it.
Reasons to Install It
- A 2" or 3" pump is moving to automated, signal-driven operation.
- Plant wiring is built around 24 VDC NEC/CEC field devices.
- White polypropylene fits the material plan for that pump.
One kit covers both the 2" and 3" sizes, but the pump nameplate is still the final word. Match its model and serial number to this listing first. Also confirm your panel can supply 24 VDC to the coil.
