What is the difference between high pressure valve and low pressure valve air compressor?
*
The key differences between high pressure and low pressure valves for air compressors are:
High Pressure Valves:
- Designed to handle liquid, gas, or corrosive fluids at pressures greater than 3,000 psi (207 bar)
- Can withstand pressures up to 15,000 psi in some cases
- Used in industrial applications like oil & gas, pharmaceuticals, and water treatment where high pressure control is critical
- Made of materials like stainless steel or carbon steel to be corrosion and abrasion resistant
- Provide tighter shut-offs and are suitable for demanding, high-pressure operations
Low Pressure Valves:
- Can only withstand pressures up to 2,000 psi (138 bar)
- Typically used in applications with temperature ranges from -29°C to +150°C
- Made of materials like carbon steel, stainless steel, and brass
- Stainless steel is the standard material due to its high corrosion resistance
- Work the same way as high pressure ball valves to control liquid or gas flow
- Can be divided into full bore or reduced bore designs based on flow passage
High pressure ball valves are engineered to safely and reliably control much higher pressure fluids compared to low pressure ball valves, which are better suited for lower pressure applications. The choice depends on the specific pressure requirements of the industrial system.
