The Roth HK, HKV, and Commercial Manifolds are made of solid brass and come already assembled.

 

The Roth HK Heating Manifold with adjustable and closable flow indicators is made of heavy-walled, corrosion resistant brass alloy, 30 mm (1.2") inside dimension, with a 27.5 mm (1.1") flat gripping surface. The manifolds are available with 2-10 connections (except 9) for heating circuits. The manifolds have 1" G female threads on both ends so the piping connections can be made on either the left or right side.

• The supply manifold has flow indicators that have built-in adjustment and stop valves for adjusting the flow rate of each heating loop. The indicator is scaled from 0.02 to 1.5 US gal/min (0.1 to 6.0 l/min). The flow indicators are 2.17" (55 mm) on center.
• The return manifold has valve assemblies that can be used for isolation or for mounting thermostat-controlled electric actuators. The protective cap can be used to close this valve by completely tightening the cap. The valve assemblies are 2.17" (55 mm) on center.
• The drain and vent valve assemblies and supply/return adapters can be installed on either end of the manifold as required by the installation. The drain assembly can be rotated for easy purging of the air in the tubes.
