Product Overview

n Choice of 16 ﬁ xed ﬂ ow cartridges which

automatically controls the ﬂ ow rate to each

emitter regardless of differential pressure

changes.

n Compact design featuring ½”, ¾” and 1” union

end connections and choice of NPT, Sweat

and Press ﬁ ttings for ease of installation and

maintenance.

n Suitable for hydronic and plumbing applications,

constructed of DZR low-lead brass (Certifed low

lead).

n Eliminates the need for on-site measurements and

trial and error ﬂ ow rate setting as required with

manual calibration valves.

n Incorporates an ﬂ ow cartridge, made of an anti-

scale, low noise polymer.

n Ideal for applications including open fan coil

systems and hot water recirculation balancing.

PRODUCT RANGE - FLOWCAL™ 127 SERIES TECHNICAL SPECIFICATIONS 127 SERIES The FLOWCAL flow cartridge is composed of a cylinder, a springloaded piston, and a combination of fixed and variable orifices through which the fluid flows. These variable orifice sizes increase or decrease by the piston movement, contingent on the system’s fluid thrust. A calibrated spring counteracts the pressure to regulate the amount of fluid which may pass through the valve orifices, maintaining a balanced system.
