In the industrial sector, high temperature and high pressure safety valves are indispensable safety guardians in fluid piping systems. When the pressure inside the system exceeds the preset safety value, this safety valve will act quickly to release the excess gas or fluid, thus ensuring that the system will not malfunction or have an accident due to high pressure.
Product Functions
The core responsibility of the high temperature and high pressure safety valve is to protect the system. Once the pressure in the system exceeds the permissible range, the safety valve will open immediately to discharge the excess gas or fluid into the atmosphere or outside the pipeline, keeping the system pressure at a safe level. It is especially worth mentioning that when used in high temperature working conditions above 350℃, this safety valve is usually equipped with a radiator or designed with a flower basket type valve cover to ensure that the spring can dissipate heat well and keep it working below 350℃, thus ensuring its rigidity and stable performance.
Product advantages
Precise calibration pressure: the deviation is only ±3%, ensuring the accuracy of system pressure control.
Small opening and closing differential pressure: the opening and closing differential pressure is not more than 15%, improving the sensitivity and reliability of valve operation.
Large displacement design: full opening structure, can quickly release a large amount of gas or fluid, effective pressure reduction.
Recoil disk parts: The valve flap is specially designed with a recoil disk to enhance the valve performance.
Efficient heat dissipation: Unique radiator structure enables the valve to operate stably at higher temperatures.
Open bonnet: suitable for high temperature media, improve the scope of application of the valve.
High-quality spring steel: the selection of high-performance spring steel to ensure long spring life and stability.
Easy maintenance: Flat structure of the valve flap and seat, easy to repair and rework.
Flexibility test: equipped with a lifting wrench, you can regularly check the flexibility of the valve opening to ensure that it is always in the best condition.

Installation guide
To ensure the best performance and long-term reliability of the high-temperature and high-pressure safety valve, please follow the installation steps below:
Vertical installation: The valve should be installed vertically at the highest point of the equipment for effective pressure relief.
Fixed support: The main safety valve should be fastened to a support that can withstand the reaction force generated by the vapor discharge.
Specialized hangers: The exhaust pipe should be equipped with specialized hangers to avoid putting weight on the main safety valve and to ensure that the connecting flanges are not subjected to additional pre-stress.
Trap design: The lowest point of the vapor exhaust pipe should be considered for trap design to prevent water shock when exhausting the vapor, which affects the safety of the system.
High-temperature and high-pressure safety valves play a vital role in industry with their excellent performance and wide range of applications. With proper selection and installation, this safety valve will become an indispensable safety guard in your fluid piping system.
