2 alancing Service egulation of multi-circuit chilled water and hot water systems is essential to achieve design performance. MILLNTI valves have excellent throttling characteristics through full travel and are ideally suited for balancing duty. Two (2) pressure tapping points are provided on the valve body, and check valves, pet cocks, or PT plugs can be fitted as requested. n adjustable memory stop is included as standard on all wrench operated valves, and memory stop gear operators should be provided on all valves requiring gears. fter the desired signal has been attained during the balancing procedure, the memory stop or memory gear can be adjusted so that the valve may then be used for isolation purposes and re-opened to the balancing position. In order to retain the plug at the required position, an adjustable torque collar is provided as standard on wrench operated valves, and gear operators can be supplied on all valve sizes. The adjustable torque collar and gear operator prevent any rotational movement of the plug due to flow, and particularly under high velocity flow, assists in preventing slamming and subsequent pressure surges. page 1 page 2 Valves can be supplied with either two (2) check valves (illustrated above) or two (2) hand operated pet cocks (illustrated below) to be used in conjunction with a portable differential meter to measure the pressure drop across the valve when balancing a hot or chilled water system. PT plugs are also available upon request.

3 Valve Specification OVVIW OF VLV TILS The Milliken criteria of quality, reliability, safety and value are embodied in the MILLNTI balancing valve, setting higher standards for dependable performance with excellent features achieved by the utilization of the very latest design and manufacturing techniques. ~ omputer ided esign ~ High Integrity asting ~ N manufacturing delivers consistent sizes on all components ll complemented by a rigorous Quality ontrol System ody MILLNTI valve body casting is in STM 126 L cast iron for class 125 valves on sizes 2-1 /2" and larger, and STM ductile iron for class 250 valves and 1 /2" - 2" valves, using high pressure molding techniques. Flanged, grooved, and threaded ends are available. Grooved ends meet NSI WW -606 for ductile or steel pipe. Seat The MILLNTI valve incorporates as standard, on 3" and larger, a 1 /8" thick welded 99% nickel seat for corrosion and erosion resistance specifically profiled for low torque and extended seat life. 2-1 /2" and smaller sizes are furnished with an overlay of corrosion and abrasion resistant epoxy. Stem Seal High integrity sealing by combining the advantages of a resilient and abrasion resistant U-cup seal. From vacuum to high pressure, the self-adjusting seal system gives positive, trouble-free service and is retained independently of the plug stem or external torque device, thereby eliminating periodic maintenance. earings The plug rotates in permanently lubricated stainless steel bearings, located in the body and bonnet, along with upper and lower PTF thrust washers, which ensure consistently low operating torque. Plug Supported on integral trunnions, the plug is totally encapsulated with an elastomer that is molded. High integrity sealing is achieved by a variety of elastomers which protect the plug right up to the trunnions. When assembled, the light compression of the elastomers onto the PTF thrust washers prevents entry of abrasive materials in the bearings. onnet Seal Superior O ring sealing with metal/metal contact means lower bolting stresses compared with compression gaskets. Flow The port design (round on 1 /2"- 12" and rectangular on 14" and larger) with streamlined internal contours gives the highest industry capacity straight through flow in the full open position, reducing turbulence and pressure drop. Travel Stops djustable open and closed travel stops are fitted as standard on both wrench and gear operated MILLNTI valves. Flow harts ertified flow charts to be supplied when requested. The flow data testing is completed by a 3rd party testing facility. page 3 page 2

4 esign and onstruction Milliken balancing valves are designed specifically for balancing hot and chilled water systems in multi-story commercial buildings, schools, hospitals, or any facility that uses hot or chilled water for heating and cooling. The balancing valves provide an accurate means of adjusting and reading flow in condenser and hot or chilled water systems. These valves maintain the desired flow, balance point and temperature throughout the building. The valves are constructed to allow the required flow to be balanced by using the flow curve charts and the use of memory stops on either wrench or gear operated valves, and also allows the valves to be shut off and returned to the memorized open position. The valves are designed to allow smooth flow through the valves. The plugs are completely elastomer coated, supported on oil impregnated stainless steel bearings for long maintenance free life. Flow measurement is by upstream and downstream Schrader fittings, PT plugs, or hand operated pet cocks for use with differential meters. ll sizes have been rigorously flow tested for repeatability of flow, and comprehensive flow charts are available.
