Thermodynamic Disc Steam Trap is designed to trap the steam inside a hot water pipeline. The trap uses a simple thermodynamic principle that the steam rises above water. The trap has an inlet, outlet a chamber to trap the stem and other smaller components. The Thermostatic Disc Steam Trap lets the hot water in and the disc sits on top of the inlet. While there is no steam, the chamber above the disc is empty. This means, there is no pressure above the disc. So the incoming water pushes the disc above and flows through the outlet. This is the opening position of the trap. While there is steam in the water, the steam gets above the water and builds up inside the chamber above the Thermal Disc Steam Trap. When steam builds up, it forces the disc to lower and close the inlet.

This way, the water flow is stopped, but the steam keeps building up. As the pressure increases above, the steam starts to condense. Once the steam has condensed into water, the pressure above the Thermo Disc Steam Trap disc goes down. When the pressure below is higher than the pressure above, it pushes the disc upwards opening the outlet and the water starts to flow again. The trap does not need any adjustment while at operation. The Disc Type Steam Trap can come in different materials but the ductile iron materials are more common. The traps also come in various sizes and dimensions according to the standards and the application pipeline size.

In a thermodynamic disc steam trap, the flow of condensate is controlled by a circular shape valve head (valve disc) opening and closing against the valve seat. The valve disc is disconnected from all other parts of the trap, and rests on top of the valve seat.

High Temperature and High Pressure Disc Steam Trap works at high temperatures and pressures. Applications such as the oil and gas, petroleum, boiler, condenser, heat exchanger and power plant pipelines all use the High Temperature High Pressure Disc Type Steam Trap in operation. The trap works with a disc inside the chamber responding to the temperature and pressure. The disc opens up the inlet valve when the pressure drops inside the system. Once steam enters the system, it forces the disc to close the valve. The steam is captured on top of the disc inside the Stainless Steel High Temperature Disc Steam Trap chamber. The steam starts to condense and once the pressure drops below the threshold, the disc moves up to open the inlet and outlet valves.
The flow of the liquid continues until steam starts to enter the chamber. The cycle repeats without much of manual operation. The Cast Steel High Pressure Disc Steam Trap is the most commonly used but the elements inside the trap can be made up of different material types based on the liquid that is supposed to flow inside the trap. There are different pressure temperature deviations based on the applications as well. So the High Pressure Disc Type Steam Trap varies in dimensions, sizes, corrosion resistance and in temperature and pressure capacities from application to application.
