A-89 & A-43CRF Pressure Reducing Boiler Feed Valves

Brass body. Both the A-89 and A-43CRF feature an inbuilt check valve to retard reverse flow of boiler water. The A-43CRF and the A-89 feature rapid fill capability and balanced piston for closer outlet control regardless of variations in inlet pressure. Standard reduced pressure setting is 14 psi with an adjustment range from 2 to 30 psi. Maximum inlet working pressure is 200 psi. Available with threaded connection or sweat copper union inlet.

Applications:
For hot water space heating boilers. Designed for larger boilers requiring faster filling.

Sizes:
1/2"
