use on other fluids may be possible but, if this is contemplated, Spirax Sarco

a safety device is included in the system to prevent such over-limit situations.
iii) Determine the correct installation situation and direction of fluid flow.
iv) Spirax Sarco products are not intended to withstand external stresses that may
be induced by any system to which they are fitted. It is the responsibility of the
installer to consider these stresses and take adequate precautions to minimize
them.

plates, where appropriate, before installation on steam or other high temperature
applications.
