The PN16 Proportional Lift Safety Valve is engineered to provide controlled, gradual pressure relief in industrial systems. Unlike full-lift valves that open instantly at set pressure, proportional lift valves begin opening progressively as pressure approaches the limit—offering smoother, more stable system protection.
This spring-loaded safety valve discharges excess steam, air, or gas when the system reaches the preset maximum pressure or temperature, preventing catastrophic failures such as boiler explosions, tank rupture, and pipeline damage. Its precise proportional lifting mechanism ensures both sensitive response and reduced mechanical stress on the system components.
The reliable and durable construction makes this valve ideal for continuous industrial use where stable overpressure protection is required.
