4500D Temperature & Pressure Control Valve

The AMOT 4500D is a combined temperature and pressure control valve used in applications where both temperature and pressure control are required simultaneously. The AMOT 4500D valve combines temperature control, pressure regulating and pressure relief into a single manifold valve, reducing installation costs and simplifying material planning. The valve is designed to be mounted directly on the oil tank to reducing piping.

The AMOT 4500 temperature & pressure control valve has been specifically designed and developed by AMOT Controls as a pressure and temperature regulating valve for lubricating oil applications. The pilot regulates the oil pressure operated Cartridge Regulator. The pilot feed to the Regulator is taken downstream of the oil filters to sense the oil pressure. Pressure is controlled by regulating the amount of oil that is dumped through the Cartridge Regulator back to the main reservoir.

The temperature of the oil is then controlled by the internally sensed 3-way temperature in the control 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-controlled oil exits the valve and flows through the lube oil system filters before flowing to the equipment requiring lubrication.
