IQVALVES控制阀IQ PFCV系列产品介绍

iQ Valve’s new breed of patented, solenoid operated, proportional flow control valves are unparalleled in the valve industry. Our PFCV (Proportional Flow Control Valve) line outperforms the other types of proportional valves through unique design innovations.

iQ Valve’s proportional valves have no rubbing contact surfaces which gives them low hysteresis, high frequency response, quick time response (less than 35 msec.) and long life. Since no sliding friction is encountered, the electrical drive circuit can be as simple as a straight DC electrical signal; however, a pulse-width-modulated signal can also be used. These single-stages, 2-way poppet valves will perform well even at low pressure drops.

Our patented pressure balanced designs allow us to create flow control valves that can operate, even when pressure is fluctuating. The poppet construction eliminates leakage within the working pressure ranges. The working fluid is isolated from the coil and other parts of the solenoid by an isolation diaphragm; thus, the fluid path is limited exclusively to the poppet area and the inletand outlet paths. This feature makes these valves suitable for both gases and liquids.

iQ Valve 的新型专利电磁操作比例流量控制阀在阀门行业中是优质的。PFCV（比例流量控制阀）系列通过独特的设计创新优于其他类型的比例阀。

iQ Valve 的比例阀没有摩擦接触面，因此具有低滞后、高频率响应、快速响应（小于 35 毫秒）和长寿命。由于没有遇到滑动摩擦，电气驱动电路可以像直接直流电信号一样简单；然而，也可以使用脉宽调制信号。这些单级 2 通提升阀即使在低压降下也能表现良好。

获得的压力平衡设计使我们能够制造出即使在压力波动时也能运行的流量控制阀。提升阀结构消除了工作压力范围内的泄漏。工作流体通过隔离膜片与线圈和螺线管的其他部分隔离；因此，流体路径仅限于提升阀区域以及入口和出口路径。这一特点使这些阀门适用于气体和液体。
