The Purpose of Drain Valves

Industrial air compressors are used in construction, manufacturing, and other industrial settings.

Fleet vehicles or transport trucks that use air compressors to inflate tires.

Medium-sized home workshops equipped with an air compressor.

Large commercial shops, garages, or workshops that use air compressors to power tools and equipment.

Automotive repair shops that use air compressors to power brake blowers and other automotive equipment.

Types of Drain Valves Used for Compressed Air

Automatic drain valves: These valves are designed to open and close automatically based on a preset schedule or pressure level. They are typically installed at the lowest point in the system, where condensate is likely to collect. Automatic drain valves can be controlled by a timer or a pressure switch, and they can be set to open and close at specific intervals to ensure the system is properly drained.

Manual drain valves: As the name suggests, these valves must be manually opened and closed by the operator. They are typically located at the lowest point in the system and are used to release excess moisture and contaminants on an as-needed basis. Manual drain valves are often used in systems that do not require frequent draining, or in cases where automatic draining is not practical.

Float-operated drain valves: These valves use a float mechanism to open and close the valve as the level of condensate in the system rises and falls. The float rises with the level of condensate and activates a switch that opens the valve when the condensate reaches a certain level. Float-operated drain valves are often used in systems with high moisture content or in areas where automatic draining is not practical.

Thermally-activated drain valves: These valves are designed to open and close based on the temperature of the system. They are typically installed at the lowest point in the system and are activated when the temperature reaches a certain level, indicating that condensate has formed. Thermally-activated drain valves are often used in systems with high moisture content or in areas with extreme temperature fluctuations.

Q: My customer didn't need the product – can I return it?

A: Yes, although there may be a 25% restocking fee depending on to circumstances. Please contact your salesperson for additional details.

Q: Can you send me a drawing/spec sheet/submittal?

A: Yes, if it's an existing one on file. If not, an REA form will need to be filled out for one of the Engineers to create.

Q: What is the purpose of draining valves?

A: The critical purpose of a drain valve is to enable surplus water vapor to escape into the atmosphere. The removal of condensation aids in the prevention of corrosion, which can harm the compressor and reduce its lifespan.

Q: Should the drain valve be open or closed?

A: If the unit will not be used for a long time, it is advisable to keep the drain valve open until it is needed. This allows moisture to drain entirely and prevents rusting on the interior of the tank.

Q: Where should drain valves be installed?

A: Above the internal stop valve, a drain-off valve must be fitted. It is the property owner's obligation. The building water service is made up of the communication and supply pipes.

Q: Which way do you turn a drain valve?

A: To open the drain, look at the handle of the drain valve and turn it counterclockwise. Close the drain by turning it clockwise. It's common for new valves to be difficult to turn. If necessary, use pliers; the valve will not be damaged.

Q: Why is the drain valve used in air bottles?

A: To remove collected condensate from the receiver, a drain valve is installed at the bottom of the bottle.

Q: How should a drain valve be installed?

A: Installation of an air compressor drain valve varies depending on the type of valve and the specific compressor. It is important to follow the manufacturer's instructions and consult a professional if necessary.

Q: What is the difference between drain valve and isolation valve?

A: Vent and drain valves are examples of normally closed valves which are only opened when required to depressurise (vent) or drain fluids from a system. Isolation valves must effectively stop the passage of fluids. Gate valves, ball valves and plug valves are generally considered to provide tight and effective shut-off.

Q: When to use a valve with a drain?

A: Ball valves with a drain port use this feature to drain fluids or debris from the system. They are often used in applications where it is necessary to completely drain the system or remove residual fluid after shutting off the valve.
