For example, a 60-gallon air compressor tank would need a drain valve with a flow rate of at least 6 GPM.
3. Pressure Setting
Pressure-based drain valves have a pressure setting that determines when the valve will open and drain the tank. The pressure setting should be adjusted to match the operating pressure of your air compressor.
Most drain valves come with a factory-set pressure setting, but you may need to adjust it to ensure that the valve opens at the correct pressure. If the pressure setting is too low, the valve may open too frequently and waste water. If the pressure setting is too high, the valve may not open often enough and condensation can build up in the tank.
4. Material
Automatic drain valves are typically made from brass, stainless steel, or plastic. Each material has its own advantages and disadvantages:
- Brass: Brass is durable and corrosion-resistant, but it can be more expensive than other materials.
- Stainless steel: Stainless steel is highly corrosion-resistant and can withstand harsh environments. It is also very durable, but it can be more expensive than brass.
- Plastic: Plastic is a less expensive option, but it may not be as durable as brass or stainless steel.
The best material for your automatic drain valve will depend on your specific needs and budget. If you need a valve that is highly corrosion-resistant and durable, stainless steel is a good choice. If you are on a tighter budget, brass or plastic may be a better option.
