FLANGES Check-Trol
™
Isolation Flow Control Flange

Description
The Check-Trol flange is a combination isolation valve, flow control
valve, and companion flange for circulators. The ball valve allows
the circulator to be removed from the system without draining the
system. The internal spring check prevents gravity circulation. Free
floating companion flange makes pump installation a snap.
