UNT-PRC001-EN.book Page 20 Tuesday, May 8, 2012 10:54 AM General Data Piping Packages Factory-Installed Piping Packages UniTrane fan-coils have standard piping packages available as a factory built and installed option. Piping package options are also available for the hot water reheat coil on two-pipe units equipped with either a fan speed switch or Tracer ZN520 and UC400 controller. Factory built assures all piping packages are fully tested under water for leaks and are built within strict tolerances.
PAGE 21
UNT-PRC001-EN.book Page 21 Tuesday, May 8, 2012 10:54 AM General Data Piping Packages The deluxe piping package also includes a strainer on the entering water pipe and unions at the coil connections along with the basic components. The strainer body is cast brass construction, with a stainless steel mesh strainer that is easily removed for cleaning. The unions are forged brass construction and close with a minimum amount of effort.
PAGE 22
UNT-PRC001-EN.book Page 22 Tuesday, May 8, 2012 10:54 AM General Data Piping Packages Three-Way Modulating Valves These valves modulate the water flow through the coil in response to a signal. Three-way valves allow water that is directed through the coil to mix with water that is directed through the bypass line. This mixture exits through the leaving water pipe. All modulating valves are three-wire floating point equal percentage valves.
PAGE 23
UNT-PRC001-EN.book Page 23 Tuesday, May 8, 2012 10:54 AM General Data Selecting the Correct Modulating Valve Size Modulating valves are available in any of four port sizes. The port sizes relate to a Cv of 0.6, 1.1, 2.3, 2.7, 3.3, and 3.8, which is the coefficient of flow. The coefficient of flow is defined as the volume of water flow through a control valve in the fully open position with a 1 psig differential across the valve.
