FlowCal™ 3/4 In Male Compact Automatic Recirculation Balancing Valve (NPT), Series 127

Balancing hydronic circuits is crucial for achieving optimal system performance and efficiency, thereby meeting desired comfort levels. This FlowCal compact automatic recirculation balancing valve automatically maintains the design flow rate to each terminal unit despite changing differential pressure changes across the circuits. With an exclusive scale-resistant, low-noise cartridge and compact body, FlowCal is ideal for controlling flow to fan coils, baseboards, radiators, or plumbing fixtures in hot water recirculation systems. Balancing is fast, easy, and efficient.
