2.1 Overview
The 2230C and 4430B Temperature Sensing Valves are normally closed, two-
way valves which are opened when the temperature of the process medium
increases above a preset setpoint.
The control pressure applied to the valve can be air, gas or lubricating oil and
is vented when the valve opens. This reduces the control pressure to an AMOT
Master Safety Control or other device to protect the engine when high
temperature is detected.
Fig 1 shows a typical installation using two Temperature Sensing Valves
connected in series. This ensures that the shutdown system is triggered in the
event of high temperature cooling water or gear case.
The orifice ensures that the pressure drop is transmitted to the shutdown
system device in large volume systems.
