Sun regeneration valve assemblies are standard products that are easy to order. Regenerative circuits divert the oil from the rod end of a cylinder back to the bore end, instead of channeling the fluid to tank, allowing for faster speed and reduced force. Using a cylinder with a 2:1 area ratio between piston and rod provides equal extend and retract speeds. Sun manufactures two types of regeneration valve assemblies.
• Full time regeneration assemblies use a pilot-to-close check valve and a standard check valve to provide continuous regeneration with reduced output force from the cylinder. They provide fast extension speeds with low force.
• Pressure sensitive regeneration assemblies use a pilot-to-close check valve and a counterbalance valve to provide a regeneration function. The first part of the cylinder extension begins with regeneration, when there is very little load. When the load resistance increases, the pressure on the full-bore side starts to increase. As the bore-side pressure increases, pilot pressure will begin to open the counterbalance valve, connecting the rod side of the cylinder to tank, causing the regeneration function to cease. The cylinder will now extend with pressure acting on the full-bore area for increased force, but with reduced speed.
They are available in Line Mount and Sandwich assemblies, with flows ranging from 40 to 910 l/min and can incorporate load locking. Sun’s regen solutions are ideal for compacting machines as well as presses and machine tool applications when speed and/or force control are required.

Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
