Compressor Control Valves - What They Are & Why They're Important

Do you know what a compressor control valve is and how it works? If not, you’re not alone. But knowing about compressor control valves is essential if you own or work on a compressor, as they play an important role in loading and unloading cycles. we’ll outline the basics of these valves and explain their benefits. We’ll also discuss how they work and why it’s important to have one on your compressor. Finally, we’ll provide an overview of the installation process for these valves, so that you can be sure your compressor is equipped with the proper control valve.

What is a compressor control valve?

Compressor control valves are absolutely essential for maintaining safe working conditions, preventing over-pressurization, and regulating the pressure in air or gas systems. The control valves control the compressor’s loading and unloading cycles.

Primary control valves consist of the inlet guide vane assembly that determines how much air is drawn into the compressor and is the primary antisurge control, and the compressor discharge valve that determines how much discharge air leaves the compressor into the compressed air system.

In addition, there are two discharge control valves: the discharge check valve that prevents air from flowing backwards through the compressor; and the customer-supplied discharge block valve that isolates the compressor from the air supply during compressor shutdown.

Inspect them periodically for wear and tear, and make sure they are in working order by checking for leaks and noise.

Benefits of having a compressor control valve

Compressor control valves are essential for a healthy compressed air system. They help to regulate pressures , flow and temperatures of different essential systems inside a compressor, for example, inlet guide vane assembly determines how much air is drawn into the compressor (air Compressor supply) acting as primary antisurge control, and the compressor discharge valve that determines how much discharge air leaves the compressor.

Besides these main compressor control valves , there are other control valves in the system, for example, the discharge check valve which serves a very important function of preventing any backflow of air into the compressors, safe guarding it from surge conditions.

The Block valve in the discharge line ensures compressor isolation in case of shutdown and maintenance activities.

Control valves in oil system ensures proper pressure and flow for the bearings of the compressor and the motor. Control valve in oil mist line ensures that the oil vapor’s are being removed and a proper vacuum is maintained inside the oil tank for safe compressor operation.

How do compressor control valves work?

Most of the control valves are controlled either electrically (electronic control valve) or pneumatically through a compressor controller using a control logic to ensure proper operation, advanced noise control as per control philosophy. Contact Turbo Airtech to know more.
