Check-Trol™ Isolation Flow Control Flange

Overview

Design Features

Three features in one valve:

Check-Trol is the solution for circulator installations. Installing a Check-Trol on the discharge of the circulator gives you the features of a Flow Control Valve, Isolation Valve and Companion Flange. Another advantage of the Check-Trol is the minimal pressure drop, especially when compared to the losses that can be experienced when a check valve is installed internal to the circulator. The Check-Trol flanges are packaged with an isolation flange of the same size to create a pair. Capscrews and nuts are included.

Flow Control Valve

Prevents gravity circulation and flow in the wrong direction.

Isolation Valve

Allows for servicing or replacement of the circulator without draining the system.

Companion Flange

Free-floating companion flanges allow easy alignment for optimal handle positioning.

Available sizes:

3/4”, 1”, and 1-1/4” NPT and Sweat.
Patent Pending

Applications

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