You get what you pay for in Manifolds 
Caleffi is one of the biggest names in hydronic controls. When you want the best, you want Caleffi.

These manifolds include:

• Flow meters on each branch - This aids in set up for troubleshooting and allows for heat control on each loop of tubing.

• A Balancing Valve for each branch of the manifold - This provides maximum control and flexibility.

• Shut-off Ball Valves - for isolation and control.

• Supply and Return Temperature Gauges - for system troubleshooting and performance measurement.

• Air eliminators and purge drain - right on the manifold for easy start-up

• Top quality Brass construction for proven reliability

• Mounting Bracket for secure professional look.

• Sub-Zoneable - With the addition of an actuator on the balancing valve, each loop or any combination of loops can be a separate thermostat controlled zone.

• Models with "IN" suffix are built inverted (tubing connections going upward).
