2P25U3S/14 is an important type of liquid pressure relief valve, widely used in the automatic control equipment, refrigeration systems and oil and gas refineries for the device’s feedback control loop. It functions as a safety valve, enabling the fluid pressure within a system or in a vessel to be kept under a certain predetermined pressure. A 2P25U3S/14 relief valve has a self-adjusting pressure reducing valve; it changes the opening area or outlet pressure of the valve in order to maintain a continuous and stable pressure difference between the inlet and outlet pressure. This type of valve ensures that equipment and systems operate within their design performance range, allowing abnormalities to be promptly identified and reduced.

Application Field

A 2P25U3S/14 relief valve is generally used in systems where a known and predetermined pressure needs to be maintained, so that the functioning of the system remains stable and efficient. The precise control of this valve has made it to be widely used in the automation and refrigeration industry. It is often integrated in systems that are employed in air conditioning systems, commercial air compressors, oil and gas piping networks, heating systems, and in process cooling units. The reliable performance and accurate control of this valve has made it to be an important part of these systems. Additionally, the 2P25U3S/14 is used in the upstream industrial control loops of pressure vessels; it is also employed in protecting the equipment from dangerous overloads and pipe blockages.

Working Principle

A 2P25U3S/14 relief valve works on the basis of a self-adjusting pressure reducing valve, which controls the opening area or outlet pressure of the valve in order to maintain a continuous and stable pressure difference between the inlet and outlet pressure. The pressure relief valve can also be set to have a certain outlet pressure by using an adjustment knob. Its operation is characterized by two adjustments: one is the main valve, which regulates the maximum outlet pressure, and the other is the pressure setting knob, which sets the structure of the valve. Depending on the pressure setting, the valve automatically adjusts the outlet pressure for a functional balance between the inlet and outlet pressure.

In general, the outlet pressure is set to be slightly lower than the inlet pressure to ensure proper operation of the system. The structure of the pressure control device in combination with the adjustable outlet pressure, makes the 2P25U3S/14 relief valve an ideal choice for pressure control systems, where a controlled and stable outlet pressure is required to maintain a constant flow within the system. The efficient operation of this valve ensures quick and effective leak prevention as well as the protection of personnel when the system is subject to overpressure.
