A. Call Excel! As the cylinder has a large volume of oil within its body, under pressure this oil compresses. When the directional valve shifts to allow the cylinder’s direction to change, this oil decompresses rapidly causing the bang. With expert fitting of additional valving this fluid can be decompressed and therefore do away with the destructive banging.
