Valve Piping Packages

Indoor heating and cooling control

Piping packages control the flow of water to the hydronic coils on fan coils, blower coils, and VAV boxes. Proper piping package design and installation is critical to the operation of your hydronic system.

  • Available in ½", ¾", 1”, 1 ¼" and 1 ½" valve sizes
  • 2-way or 3-way valve bodies
  • On/Off, modulating, or proportional type actuator

Product Overview

Standard factory-assembled piping packages consist of a 2- or 3-way on/off motorized, electric control valve and two ball-isolation valves. Available options include 2-way and 3-way modulating or proportional control valves, fixed-flow (FC) and adjustable (PICV) control devices, pressure temperature (P/T) ports, unions, and y-strainers with a blowdown valve.
