What factors should I consider while choosing a pneumatic safety valve?

Ensure it matches your system's pressure requirements.Check if it can handle your required flow volume.Confirm it suits your media and environment.Verify it meets safety standards.Choose a proven, reliable valve.Ensure it fits your system.Consider ease of maintenance and overall cost.Opt for a reputable manufacturer.

How do I clean and maintain pneumatic safety valves?

Ensure the pneumatic system is depressurised and the valve is isolated.Examine the valve for wear, corrosion, or damage.Remove dirt or debris using compressed air or a soft brush.Apply appropriate lubricant to moving parts as recommended by the manufacturer.Conduct regular functionality tests to ensure the valve operates correctly.If necessary, replace worn seals, gaskets, or damaged components.Adhere to maintenance instructions provided by the manufacturer for specific valve models.

Working Mechanism

When pressure in the pneumatic system exceeds the safe limit, it acts on the valve.
The valve's internal mechanism responds to the excess pressure.
The valve opens, allowing excess air to escape from the system.
As air is released, the system's pressure decreases to a safe level.
The valve automatically closes when the pressure stabilises, ensuring system safety.
