2 inch Pressure Relief Valve
The 2 inch pressure relief valve is an adjustable pressure relief valve to reduce the inlet pressure to a certain required outlet pressure and, relying on the energy of the medium itself, automatically maintains the stability of the outlet pressure.
From the perspective of fluid mechanics, the pressure relief valve is a throttling element that can change local resistance. That is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are altered, resulting in different pressure losses, so as to achieve the purpose of reducing the pressure. Then, relying on the adjustment of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain deviation range.
Main features of the 2 inch pPressure relief valve.
- Accurate pressure control
- Fast opening to maintain line pressure
- Slow closing to prevents surges
- Completely automatic operation

The pressure relief valve is widely used in various industrial and civil fields, mainly including the following aspects:
- Energy industry: in the transportation channels of petroleum, natural gas, and coal gas, the pressure relief valve is used to reduce the internal pressure of the system and ensure the safe and stable operation of pipeline equipment.
- Chemical industry: it controls the pressure of liquids or gases to ensure the reliable operation of equipment and systems and avoid dangerous situations caused by excessive pressure.
- Gas supply system: it is used to control the pressure stability in places such as indoor drinking water supply, heating gas supply, and industrial gas use.
- Thermal system: It controls the supply pressure of hot water to ensure the smooth and safe operation of the entire system.
- High-rise buildings and urban water supply networks: in high-rise buildings and urban water supply networks, the pressure reducing valve is used to reduce the water pressure, ensuring that each water consumption point obtains a stable service water pressure and flow rate.
- Mine and other occasions: in mines and other occasions where stable pressure is required, the pressure reducing valve is used to improve the operating conditions of the system and save water resources.
Is a leaking pressure relief valve dangerous?
Yes, a leaking pressure relief valve can be dangerous. Here are the reasons. First, a leaking pressure relief valve may lead to a loss of system pressure. In a hydraulic or pneumatic system, for example, this can cause the system to malfunction, affecting the normal operation of related equipment and potentially leading to equipment damage. Second, the leakage may be accompanied by the release of high-pressure fluids or gases. If these substances come into contact with people, they can cause physical harm such as cuts, bruises, or even serious injuries like burns in the case of hot fluids. Third, continuous leakage can also lead to environmental pollution. Fluids leaking onto the ground may contaminate soil and water sources. Moreover, the leaking fluid or gas may be flammable or explosive. In such cases, there is a significant risk of fire or explosion, which poses a serious threat to the safety of people and property in the surrounding area. In conclusion, a leaking pressure relief valve is a potential hazard that requires timely attention and repair to ensure the safety and normal operation of the system.
What is high pressure relief valve?
A high pressure relief valve is a safety device designed to protect pressurized systems from exceeding their maximum allowable pressure. It automatically opens at a predetermined pressure to release excess pressure, preventing potential equipment failure or explosions.
