1. Maintain proper system performance

• Delivers the precise amount of fluid needed
• Keeps engines, cooling systems, or hydraulics running smoothly

Example: Too much fuel = waste and smoke
Too little fuel = loss of power

2. Prevent damage

• Stops overpressure or fluid overload
• Prevents components from running dry

This helps protect expensive parts like pumps, compressors, or engines.

3. Improve efficiency

• Avoids wasting fuel or energy
• Helps systems operate at optimal levels

4. Control pressure and flow stability

• Keeps flow steady instead of erratic
• Maintains consistent system behavior

5. Support system regulation and automation

In modern systems, it works with controllers to:

• Adjust flow automatically
• Respond to changing conditions (load, temperature, demand)

Inconsistent or erratic operation

• System works fine, then suddenly doesn’t
• Fluctuating pressure or performance
• Unstable behavior (surging, cycling on/off)

Poor performance

• Loss of power (in engines)
• Weak cooling (in refrigeration units)
• Slow or weak hydraulic response

Over- or under-delivery of fluid

• Too much fluid → flooding, overpressure, inefficiency
• Too little fluid → starvation, overheating, poor function

Unusual noises

• Hissing, knocking, or chattering
• Often caused by unstable flow or pressure

Leaks

• Fluid leaking from the valve body
• Indicates worn seals or internal damage
