 SERVICE RECOMMENDATION
  1. The globe valve is normally installed with flow direction and pressure under the disc. In case the flow in valve directs to the opposite direction, always check at factory before installing the valve. Under a certain service condition, especially when a valve is equipped with cylinders or electric motor actuators, there is a cost advantage in designing and installing the valve flow over the disc. If the actuator is sized to such condition, care must be taken to install the valve correctly.
     
  2. The globe valve is suitable for most throttling applications; however, it must not be used for a prolonged throttling at 10% open or less, which may cause excessive vibration, noise or damage to disc and seat. Use of small valves with a lower flow capacity may permit the valve to be opened to a greater percentage, and thus avoid damage. For continuous severe throttling, a control valve is required.
