Circuit Balancing <strong>Valves</strong><br />
NIBCO Puts You In Control.....<br />
With Circuit Balancing <strong>Valves</strong><br />
New NIBCO ® Circuit Balancing <strong>Valves</strong> control and maintain a comfortable indoor climate while saving energy and<br />
reducing costs. These control valves ensure trouble-free operation and ease of maintenance.<br />
Why Balance Your System?<br />
Whether a system is designed for heating, cooling or water distribution, it must be properly adjusted and balanced<br />
for optimum design performance. An unbalanced system may produce temperature variations of up to 14° F<br />
between rooms, which can add up to 35% to energy costs.<br />
What are the Benefits?<br />
• A balanced system ensures a comfortable indoor climate<br />
• The correct flow in boilers and chillers<br />
• The desired flow distribution throughout the building<br />
• Energy savings and cost savings<br />
• Trouble-free operation and ease of maintenance<br />
• Lower capital cost<br />
Series 1710 – DZR Brass Balancing <strong>Valves</strong><br />
The 1710 series threaded and solder end range are ”T“ pattern globe style valves.<br />
Unique design features in the 1710 give improved flow measurement accuracy as well<br />
as a lower head loss characteristic compared to other valves.<br />
• Memory stop feature provides repeatable regulation and control<br />
• Valve position clearly visible in the hand-wheel display window<br />
• Accurate across all valve positions<br />
• Positive shut-off and isolation<br />
• Dezincification resistant alloy<br />
• ¹⁄₂" through 2" size range<br />
Series 1709 – DZR Brass (Mini) Balancing <strong>Valves</strong><br />
Offered in ¹⁄₂" and ³⁄₄" solder end configuration only the 1709 series valve is an<br />
economical option for circuit balancing. Used in applications where standard<br />
size valves just won't fit.<br />
• Globe style for greater control<br />
• Integral test points<br />
• Memory stop feature<br />
• Dezincification resistant alloy<br />
Series 737A – Iron Balancing <strong>Valves</strong><br />
The 737A series flanged and grooved end range is from 2¹⁄₂" through 12". Cast iron<br />
bodies and ductile iron bonnets are standard.<br />
• Non-rising stem design<br />
• Positive shut-off with EPDM elastomer disc<br />
• Graphite stem sealing<br />
• Linear scale with subdivision increments for accurate position indication<br />
• Discrete memory stop<br />
• Extended test points for easy access of balancing devices<br />
