Functions of Drain Valves
Understanding the functions of drain valves is pivotal in appreciating their importance. Here are some key roles they play:
Fluid Removal:
Drain valves efficiently remove unwanted liquids or gases, preventing the accumulation of contaminants or impurities within systems.
Maintenance:
Regular draining ensures that systems remain in optimal working condition, reducing the risk of damage or malfunction.
Safety:
In emergency situations, the ability to quickly shut off the flow of hazardous substances is critical, and certain types of drain valves excel in this aspect.
- Drains that are visible on the bottom skin are lightning safe and can withstand a fire resistance test without leakage or allowing any internal surfaces to exceed safe fuel tank temperatures
- Can have remote access capabilities – providing flexibility in access and installation location
- Can have secondary seal that permits O-ring replacement with fuel in tank
- Can meet requirements of TSO-C76
Types of Drain Valves
Drain valves are available in many types, meeting the needs of different system components. Examples include:
Float-operated:
This valve allows water to flow into a special housing. When the water inside the tank reaches a predetermined level, a float triggers the drain’s opening and lets the excess water drain out.
Timer-controlled:
A timer-controlled valve opens and closes at pre-set intervals. This type of system is ideal for highly regulated operating environments.
Zero-loss:
This drain valve type contains a sensor probe that monitors water accumulation inside the tank. When the water reaches a specified level, the probe delivers an electrical signal to a solenoid. The drain then opens, but the water flow stops before the release of compressed air.
Parts of Drain Valves
A drain valve is made up of a stem and a hollow cylindrical body. The stem runs parallel to the hollow section of the body’s axis. When the stem is open, liquid or gas travels through the hollow area of the body. The stem closes the passage through the body when it is rotated, thereby preventing the liquid or gas from leaving. The stem of certain drain valve designs prevents the flow, whereas the stem of others is employed to raise or lower a flow-blocking gate. Depending on the design, this gate might be in the shape of a disk or a ball.
