Calbalance NPT

Hydraulic separators are used to isolate primary circuits (boiler) from secondary circuits (application/heat transmitter) as much for flow than for charge loss. The size of hydraulic separators should be determined by the maximal inlet flow. The information used must be the highest, no matter if it’s from the primary or secondary circuit.


• Equipped with Calvent automatic air vent (#CV050)
• Separate air and dirt
• Offered with drain valve
• Zinc plated steel housing
• Provided with wall bracket
• Maximum operating pressure 150 psi
