Our News How solenoid valves have evolved
Posted:Dec 08, 2022 Views:213 Back to List
Development of the basic design principles has led to reduced energy consumption with the introduction of the direct acting double coil design. This uses two independent windings with high and low power. The high power coil opens the valve and then integrated electronics switch over to the low power coil to provide the holding force. This twin coil approach provides sufficient power to open the valve, but then uses 75 percent less power to hold the valve in position.
The design of the coil and its operation has a direct effect on the performance of the valve. The latest energy saving designs, even in single coil conventional formats, can allow the coil to be overexcited to open the valve and within half a second, the current is reduced by 95 percent, which is still sufficient to hold the valve in the open position. The cumulative effect of this type of feature can have a significant impact on the energy required for process control. |
