Piping
The valves should be mounted in a weather-protected area in a location that is
within the ambient limits of the actuator. Allow sufficient room for valve with
actuator and for service. The preferred mounting position of the valve is with
the valve stem vertical above the valve body, for maximum life. However, the
assemblies can be mounted with valve stem vertical above the valve or up to
45° in relation to the horizontal pipe. The actuators should never be mounted
underneath the valve, as condensation can build up and result in a failure of
the actuators. Do not reverse flow direction.
