Installation Considerations Mounting Angle of Valve Assembly Be sure to allow the necessary clearance around the valve assembly. The valve assembly must be mounted so that the actuator is horizontally even with, or above, the valve. This ensures that any condensate that forms on the valve body will not travel into the actuator, where it may cause corrosion or electrical malfunction.
Insulation of Ball Valve Assembly The ball valve should be completely insulated to minimize the effect of heat transfer and condensation at the actuator. Caution: The actuator itself must not be insulated. Doing so can result in excess heat or condensation within the actuator. Temperature Limits for Ball Valve Assembly When installing the ball valve assembly, observe the minimum and maximum temperature limits. Refer to the valve and actuator specifications on pages 7, 12, 15, 18, 21, and 24.
Flow Characterization for Proportional and Floating Control The Vx-2x13-xxx-9-xx series ball valve assemblies provide equal percentage flow, which is achieved with a flow characterizing insert (Figure-13). The parabolic shape of the orifice allows a gradual change in flow, so that equal movements of the valve stem, at any point of the flow range, change the existing flow an equal percentage, regardless of the flow rate.
Cavitation Limitations on Valve Pressure Drop A valve selected with too high a pressure drop can cause erosion and/or wire drawing of the flow characterizing insert. In addition, cavitation can cause noise, damage to the valve trim (and possibly the body), and choke the flow through the valve. Do not exceed the maximum differential pressure (pressure drop) for the valve selected. Refer to the chart in Figure-15.
Using Pipe Reducers with 2-Way Ball Valve Assemblies The following table provides estimated effective Cv’s when using pipe reducers with 2-way ball valve assemblies. Use these estimated effective Cv’s in place of the rated Cv’s when reducers or increasers are located within 6 pipe diameters upstream and 3 pipe diameters downstream of the valve. Warning: Do not reduce the valve size to less than one-half the line size, as this may weaken the pipe reduction area.
