Valves are essential components to maintaining the performance of a reciprocating compressor. Because valves play such an important role in your compressor’s operation, we make sure that all of our valves and valve kits are in stock and ready to be shipped at competitive prices.

Our valves are manufactured using state-of-the-art CNC machining and milling. In addition, our high quality materials protect our compressor valves from premature failure.

SPECO can also provide you with necessary components to properly maintain your valves. Preventive valve maintenance will ensure the longevity of your compressor. Neglected valves cause overheating, output reduction, and eventual damage to pistons, rods and cylinders.

Our service technicians are practiced at reconditioning valves for many units.  Click here to learn more about our services.

When Do Valves and Unloaders Need Rebuilding?

There are several symptoms which may indicate the need to inspect valves for rebuilding:

> A noticeable drop in delivered air pressure

> Knocking or vibration in compressor

> An increase in air discharge temperature

> Changes in intercooler pressure on two stage units

It is important to remember that valves are the heart of any reciprocating compressor. Compressor valves are pressure activated while regulating through the compression cycle, and they open and close solely by the difference in pressure across the valve. And since a valve opens and closes during each compression cycle, it is not unusual for a valve to cycle 500,000 times per day.

Regularly scheduled valve inspections every six months will help increase the life of both your compressor and the valves themselves. If you plan on inspecting reconditioning valves yourself, our Sales Engineers will be happy to provide you with free instructions for this important process.
