| A-41 and AB-40 Pressure Reducing Boiler Feed Valves |
The AB-40 features a brass body and a combo connection which allows either a threaded or sweat
copper connection with the same union tail piece. The AB-40 also includes a check valve and provides an
inbuilt bypass for rapid filling, high pressure testing and system purging. The A-41 provides increased
capacity for larger boilers. It has threaded female connections and an iron body with a stainless steel
seat. Both the AB-40 and A-41 have a heat resistant diaphragm and seat disc, and an inbuilt strainer
screen. The reduced pressure setting is 14 psi. The maximum inlet working pressure is 200 psi.
NOTE: FOR BACKFLOW PREVENTION OF BOILER WATER INTO THE POTABLE WATER SUPPLY LINE,
INSTALL A BFP VALVE.
Applications:
Larger hot water space heating boilers that require faster filling.
Sizes:
3/4" (A-41) and 1/2" (AB-40)

| A-89 and A-43CRF Pressure Reducing Boiler Feed Valves |
Cash Acme offers the only anti-scaling boiler feed valve in the industry. The A-43CRF features an inbuilt
check valve to retard reverse flow of boiler water. The A-43CRF and the A-89 feature rapid fill capability and
the A-89 also includes a balanced piston for closer outlet control regardless of variations in inlet pressure.
Standard reduced pressure setting is 14 psi with an adjustment range to 30 psi. Maximum inlet working
pressure is 200 psi. Available with threaded connection or sweat copper union inlet.
Applications:
Larger hot water space heating boilers that require faster filling.
Sizes:
