美国PROPOTION-AIR公司成立于1985年,法人总统丹尼尔五库克利用对销售及市场推广前景的*发明一种电子式空气压力调节器。这气压装置设计以接受各种电子模拟和数字信号,以控制气动压力与准确性,而否定的影响,振动,安装位置或环境方面的关注。
Proportion-Air制造完成闭环质量电子流量控制阀门,快速响应和控制空气流量的能力从2 SCFH 250 SCFM。
我们所有的电子积木的空气流量控制阀是f系列质量流量传感器。 f系列使用高速压差技术产生一个电信号与空气的质量流量成正比——或者任何你想控制的气。
这个高速流信号能够使用各种Proportion-Air直接质量流量控制阀关闭循环气流。 根据你需要的空气流量,f系列流传感器匹配适当的流量控制阀,然后专门校准你的精确的流量范围。
每个电子流量控制阀不断地将你的命令信号,传感器信号的f系列流量传感器。 然后控制阀打开或关闭(几乎瞬间)保持吩咐流量。 *QB1TFEE150比例阀
Proportion-Air manufactures two types of flow control valves; closed loop mass flow control valves and open loop variable orifice flow control valves. The F-series mass flow transducer is the heart of the closed loop models. The F-series calculates flow based on differential pressure which results in very fast flow measurements. This flow can be connected to Proportion-Air’s pneumatic control valves as a feedback loop for closed loop control. The FCV (Flow Control Valve) is a variable orifice angle seat design. The FCV closes the loop around an internal valve position with an integral LVDT. The position of the valve directly correlates to valve flow capacity (Cv) based on careful design of the parabolic valve plug geometry.
Our Complete Line of Electronic Flow Control Valves
electronic flow controlProportion-Air manufactures complete closed-loop mass electronic flow control valves that have quick response and the ability to control air flow rates from 2 SCFH to 250 SCFM.
The building block for all of our electronic air flow control valves is the F-series mass flow transducer. The F-series uses high speed differential pressure technology to produce an electrical signal proportional to the mass flow of air – or, whatever gas you want to control.
This high speed flow signal is able to be used by a wide variety of Proportion-Air mass flow control valves to close the loop directly around air flow. Based on your required air flow rate, the F-series flow transducer is matched to the appropriate flow control valve and then calibrated specifically to your exact flow range.
Each electronic flow control valve constantly compares your command signal to the transducer signal of the F-Series flow transducer. The control valve then opens or closes (almost instantaneously) to maintain the commanded flow rate.
