ARO 637542-3-D 1-1/2" Solenoid Valve Block Kit, 24 VDC
Black polypropylene valve block with a plain 24 VDC coil; converts 1-1/2" Compact and EXP pumps to PE
The ARO 637542-3-D kit uses a plain 24 VDC coil and a black polypropylene block to put a 1-1/2" PD pump under electronic PE control.
ARO lists 637542-3-D as a conversion kit for taking a 1-1/2" PD pump to PE. Its voltage entry is plain 24 VDC, with no NEC/CEC or ATEX/IECEx marking given. Material is black polypropylene, and the kit is meant for the 1-1/2" EXP and Compact lines.
The solenoid valve block mounts on the pump and uses a 24 VDC signal to switch the air valve. Pump speed and on/off state then follow the output of your controller. See ARO's Electronic Interface Accessories sheet, or the Process Ready Pumps document, for setup details.
