Installation
General
See the outline drawings (Figures 1-2 through 1-7) for:

Overall dimensions

Process piping flange locations

Electrical connections

Lift points and center of gravity
Installation attitude does not affect actuator or fuel valve performance, but a vertical position is generally
preferred to conserve floor space as well as ease of making electrical and fuel connections. The LESV II
is designed for support by the piping flanges alone; additional supports are neither needed nor
recommended. Do not use this valve to provide support to any other component in the system. The piping
should be aligned and adequately supported such that excessive piping loads are not transmitted to the
valve body.
When the valve is flow tested at the factory, the lengths of inlet and outlet piping to the LESVII conform to
ANSI/ISA-S75.02. In order to maintain the valve flow accuracy and recovery performance in the
application, it is recommended that the installation piping lengths meet ANSI/ISA-S75.02.
EXPLOSION HAZARD—The surface temperature of this valve
approaches the maximum temperature of the applied process media.
It is the responsibility of the user to ensure that the external
environment contains no hazardous gases capable of ignition in the
range of the process media temperatures.
Due to typical noise levels in turbine environments, hearing
protection should be worn when working on or around the Large
Electric Sonic Valve. Noise levels of greater than 90 dB are possible.
The surface of this product can become hot enough or cold enough
to be a hazard. Use protective gear for product handling in these
circumstances. Temperature ratings are included in the specification
section of this manual.
External fire protection is not provided in the scope of this product. It
is the responsibility of the user to satisfy any applicable
requirements for their system.
