Key Features:
-
Spring-Loaded Mechanism: Utilizes a spring to maintain the valve's sealing force, ensuring precise and reliable operation.
-
Low Lift Design: The valve has a low lift characteristic, meaning it opens slightly to release pressure, making it suitable for applications where minimal discharge is required.
-
External Thread: Features external threading for easy installation and compatibility with standard piping systems.
-
Safety Function: Designed to automatically release excess pressure when the system pressure exceeds the preset limit, preventing potential damage or hazards.
-
Pressure Relief: Ensures safe and controlled release of fluid or gas to maintain system integrity.
Applications:
-
Commonly used in industrial systems, such as boilers, pressure vessels, pipelines, and hydraulic systems.
-
Suitable for applications involving steam, gas, or liquid media.
Advantages:
-
Reliability: Provides consistent performance under varying pressure conditions.
-
Compact Design: The low lift and external thread design make it space-efficient and easy to integrate.
-
Safety Compliance: Meets industry standards for pressure relief and safety.
Operation:
When the system pressure exceeds the set pressure, the spring-loaded mechanism allows the valve to open, releasing the excess pressure. Once the pressure returns to a safe level, the valve reseals automatically.
