Centrifugal Compressors – Flare Valve, Suction Pressure Throttle Valve
As suction pressure increases or discharge pressure decreases, the compressor head requirement will decrease and the flow rate will increase. A flare valve will avoid stonewalling or overranging driver horsepower.
Suction Pressure Throttle Valve
A throttling device can also be placed in the suction piping to protect against overpressure or to limit the horsepower demand to the maximum available from the driver.
