Isolation Flow Control Flange

DESCRIPTION

The Check-

Trol flange is a combination of 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.

The Check-Trol flange is packaged with an isolation flange of the

same size to create a pair. Capscrews and nuts are included.
