Here’s the English translation of the safety valve description:
Standards: ANSI, ASME, API, BS, DIN, and other international standards
Type: Spring-loaded, safety valve, valve
Size: 1/2" - 24" (DN15-DN600)
Material: Carbon steel, stainless steel, chromium-molybdenum steel, brass, aluminum alloys, etc.
Pressure: Maximum working pressure customizable based on model and requirements
Operation Mode: Automatic pressure release, suitable for high-pressure systems, protecting equipment from overpressure damage
This type of safety valve is commonly used in steam, gas, liquid, and other fluid systems to automatically open when pressure exceeds a safe limit, releasing excess pressure and thus ensuring the safe operation of pipelines, vessels, and systems.
Design and Manufacture: Conform to ASME, API, BS, DIN standards
Flange dimensions: Conform to EN1092-1/ANSI B16.5
Face to Face dimensions: Conform to EN 558-1, DIN3202 F4
Testing: Conform to EN 12266-1, API 598
Driving mode: Manual, pneumatic actuator, electric actuator
The Safety Valve is widely used in high-pressure systems, including steam, gas, oil pipelines, and other industrial applications. It is designed to automatically open and release excess pressure, protecting vessels, pipelines, and equipment from overpressure damage. It features reliable, stable performance with a simple and durable structure.
Valve Warranty: 2 years, unconditional replacement for quality issues.
The A21H type is suitable for equipment or pipelines carrying media such as water, air, and steam at operating temperatures ≤200°C; the A27Y type is suitable for equipment or pipelines carrying corrosive media at operating temperatures ≤200°C, serving as an overpressure protection device. The A28H(Y) type is suitable for equipment or pipelines carrying media such as air, steam, water, and nitrogen-hydrogen mixtures at operating temperatures ≤200°C; The A28Y-P/R model is suitable for equipment or pipelines with corrosive media at operating temperatures ≤200°C, serving as an overpressure protection device.
