PERFORMANCE BULLETIN 125 – Parker Solenoids Obsolete Transitioning to ASCO Brand Solenoids

Due to Parker obsoleting the solenoid models C4H470 used on AquaMatic V42 series valves and NXT Stager Controls, we will be transitioning to ASCO brand solenoid models 8314H041. The function of the valve assemblies will remain unchanged. Solenoid bodies will remain brass with similar electrical specifications and certifications. Specific parts affected are shown below.

When converting from Parker to ASCO brand solenoids, note the port numbers are different. Swap Ports #1 & 2 when changing between solenoid brands.

• Parker Port #1 = ASCO Port #2
• Parker Port #2 = ASCO Port #1
• Parker Port #3 = ASCO Port #3
