4504 Temperature & Pressure Control Valve (2” | DN50)
When critical systems rely on precise thermal and pressure control , complexity can lead to higher costs and more failure points. The 4504 temperature and pressure control valve solves this by combining temperature control, pressure regulation, and relief protection into one compact valve. Perfect for direct mounting on oil tanks, AMOT’s 4504 temperature and pressure control valve minimizes piping and simplifies installation, supporting reliable, efficient operations day after day.

- Designed for use in applications where control of lubricating oil temperature and pressure is required, such as gas turbines.
The temperature of the oil is then controlled by the internally sensed 3-way temperature in the valve. The oil flow then split between flowing through a cooler external to the valve and an internal bypass that flows directly to the thermostatic elements. The flow through the internal bypass and cooled oil returning from the cooler are mixed and regulated by the temperature elements to the desired temperature before leaving the valve. The temperature and pressure regulated oil exits the valve and flows through the lube oil system filters before flowing to the equipment requiring lubrication.
