  • After the installation, manifolds are one component homeowners and builders will actually see.

Versatility

  • 1 to 12 circuits
  • 1 in. and 1-1/2 in. trunks
  • 4-wire actuators for individual circuit control
  • Mounts in a 2x4 wall
  • Easy to add extra circuits
  • Bring supply/return in from either end
  • Each circuit can be individually balanced by adjusting the valve located under the blue cap or under the flowmeter
  • Maximum flow rates are 12 gpm for 1 in. manifolds and 20 gpm for 1-1/2 in. manifolds. Individual circuit flow meters are 0-2 gpm for 1 in. and 0-4 gpm for 1-1/2 in. manifolds.
  • Circuits can be completely isolated by closing ballancing valves under blue caps and inside flowmeters.
  • Manifolds and gauges are rated to 180°F and 80 psi pressure. Fittings are spaced at 2-1/8 in. on center.

Save Time on Installation

  • Seamless, one-piece construction
  • Already mounted on brackets
  • Easy to balance fl ow or fi nd air-locked circuits with fl ow meters
  • Easy to measure zone temperature drop
