High pressure solenoid valves play a crucial role in the petrochemical industry, with a wide range of usage scenarios and strict technical requirements.
Reactor and Process Control
Characteristics of working conditions: high temperature (up to 400 ℃ or above), high pressure, strong corrosive media (such as sulfuric acid, hydrochloric acid, chloride ion environment).
Technical requirements:
The valve body material should be lined with fluorine (PTFE/PFA) or special alloys (such as Hastelloy, duplex stainless steel);
Require high sealing, corrosion resistance, and long service life;
Material conveying and flow regulation
Application scenarios: Pipeline transportation systems for media such as crude oil, natural gas, liquefied gas, solvents, etc.
Technical points:
High pressure level (≥ 10 MPa) is required, and some hydrogenation units can even reach up to 70 MPa;
Fine chemicals, such as lithium battery electrolyte production, require higher precision control and cleanliness.
Steam and Thermal Energy Management System
Typical applications: heat tracing pipelines, heating pipelines, waste heat recovery systems.
Key Performance:
High temperature resistance (>300 ℃), thermal fatigue resistance;
Most products have passed Ex d IIC T6 explosion-proof certification, ensuring safe operation in flammable steam environments.
Security protection and emergency shutdown system
Importance: To prevent major accidents such as leaks, fires, explosions, etc.
Application example:
Refinery storage tank area, LNG receiving station, hydrogen refueling station;
Adopting a fast response explosion-proof solenoid valve, the action time can be as short as tens of milliseconds;
