Undersized valves do not have sufficient capacity at maximum load. Oversized valves do not have sufficient authority over the load in modulating applications. Oversized valves can initiate cycling and the seat and ball can be damaged because of the restricted opening. Proper Use These valves are only for use in cold, warm, hot water systems and for steam applications. They are designed for a medium temperature range of from to 0 F, at a maximum pressure of 60 psig N valves are to be operated with the appropriate Honeywell direct coupled actuators only. Water should be properly filtered, treated and conditioned according to local conditions and the recommendations of the boiler or chiller manufacturers. The installation of a strainers and filters is recommended. IMPORTNT The presence of excessive iron oxide (red rust) in the system voids the valve warranty. 6-68

6 N, N CONTROL LL LES WITH THREDED CONNECTIONS Effective C When valves are mounted between pipe reducers, there is a decrease in actual valve capacity because the reducers create additional pressure losses in the system. This is especially true for ball valves because of their high capacity. Table.

Use the Effective C, not the valve C by itself, to more accurately apply a control valve to the piping system. Multiply the C value by 0.86 to get the capacity in K S, if metric units are required.

NOTE: fter valves have been installed in the piping, the installer can determine the ball orientation within the valve from the notches in the top of the valve stem. For two-way valves, the lengthwise direction of the notch indicates the flow through the ball (i.e. when the notch is parallel to the axis of the valve between and ports, the ball will allow flow through the valve). For three-way valves, the flow can be determined by the orientation of the T shaped notch in the valve stem, as shown in Fig. 7. M9 Fig. 8. ertical valve installation
