With this configuration one cylinder, the master cylinder, is used to drive a number of slave cylinders in sequence, the result is from only one input a number of cylinders will extend and retract simultaneously.
This all works by matching annulus to full bore volumes and transferring oil from one cylinder to the next. A hydraulic service line is connected to the full bore of the master cylinder, the rod side of the master cylinder is connected to the full bore of slave cylinder number 1, the rod side of slave cylinder number 1 is then connected to the full bore of slave cylinder number 2 and so on until the last cylinder in the sequence is reached where the rod side is connected back to tank.
All cylinders are then primed using internal valves so that every cylinder is in its fully retracted state with the annulus areas filled with trapped oil. The volume of oil in the rod side of each cylinder is identically matched to the volume of oil required to extend the full bore of the next cylinder in the sequence.
●High Qualities: Cylinder body and piston are made from solid chrome steel and heat-treated.
●Great Durability: Hard-chromium plated piston with replaceable, heat treated saddle.
●Stronger Mechanical Strength: Stop ring can bear full capacity (pressure) and is fitted with dirt wiper.
●Corrosion Resistant: Perfectly passed the neutral salt spray test (NSS) Grade 9/96 hours.
●Long life span: FAST cylinders have passed over 200,000 cycles cylinder life test.
●Cleanliness: Through fine cleaning, surface detection, ultrasonic cleaning and dust-free transfer during the process, and laboratory test and real-time cleanliness detection after assembly, FAST cylinders have reached Grade 8 of NAS1638.
