Product Description
Armstrong FTV-4FA Flo-Trex Valve – 4" ANSI 125 Flanged Angle (570200-478)
The Armstrong FTV-4FA Flo-Trex valve (part number 570200-478) is a flanged Flo-Trex valve, 4" angle pattern. A Flo-Trex valve is installed on the discharge side of a pump and combines three valves in one body: a non-slam check valve, a tight shut-off valve and a calibrated balancing (throttling) valve with metering ports for flow measurement. Replacing three separate fittings with one reduces equipment cost, installation labour and the space needed in the mechanical room.
