Controllers - Valve Gate
This control is based on pump on demand technology. When the valve gates are fired, oil is used from the hydraulic accumulator. Once the pressure in the accumulator is below set point, the hydraulic pump replenishes the accumulator. The pump then rests until oil is needed again. This design eliminates waste, oil heating, and dramatically reduces electricity use. The conventional systems use a motor running all the time, or a air over hydraulic pump. These systems are wasteful. The problem with the air over oil pumps is that it takes 8 electric horse power to produce one air horse power. Both of these conventional designs have no comparison to simple pump on demand technology.
The use of one single energy source (120 volts AC single phase) means it is literally like plugging in a hand tool. The pump on demand allows for no water source needed to cool the oil. These systems come standard with time based switching. Optional sequential switching or cavity pressure switching can be added.
