A28X series safety valves are suitable for the working temperature ≤ 200 ℃ gas, oil and other media equipment or pipeline, as overpressure protection device.
Working Principle
When the pressure in the equipment exceeds the permissible value, the valve automatically opens and then discharges the full amount, and when the pressure is reduced to the specified value, the valve automatically closes to ensure the safe operation of the equipment.
Application Areas
Mainly used in air compressors, pressure vessels and industrial piping systems.
