This three-in-one innovation offers multiple benefits, such as delivering minimal pressure drop, an advantage when one considers the losses that can be experienced when a check valve is installed internal to the circulator. Additional benefits of the new product include a full port ball valve that allows the circulator to be removed without draining the system; an internal spring check prevents gravity circulation and flow in the wrong direction; and a free-floating companion flange provides for easy alignment and makes pump installation a snap.

Available in 3/4”, 1” and 1-1/4” NPT and Sweat models, the Check-Trol (patent pending) is designed to be used with all major brands of circulators, including the Bell & Gossett NRF, NBF, and SSF wet rotors, Series PL, Series 100, HV, PR and LR circulators.
