Check-Trol

Bell Gosset Check-Trol

Check-Trol Isolation Flow Control Flange

A combination isolation valve, flow control valve, and companion flange for circulators. The full port ball valve allows the circulator to be removed from the system without draining the system. The intermal Spring check prevents gravity circulation. Free floating companion flange makes pump installation a snap.

Can be used with most circulators, including NRF/NBF/SSF wet rotors, Series PLs, 100, HV PR and LR, and other manufacturers' pumps

SIZES: 3'4", 1", 1-1/4" NPT & Sweat.
