The Caleffi TwistFlow distribution manifolds use integrated balancing valves, enabling precise 0.25- to 2-gpm adjustment to each circuit. These manifolds are used for distributing fluid to emitters used in hydronic heating or chilled water systems. Simply twist a circuit stem and read the flow rate on the integral scale. Universal compression fittings are compatible with all brands of PEX or PEX-AL-PEX tubing. TwistTop thermo-electric actuators have “popup” indicators that give visual indication fluid is flowing.
