KROM SCHRODER控制阀RV系列产品介绍
控制阀RV设计用于调节流量，以调节燃气和空气设备上的受控燃烧过程，这些过程需要高达100：1的大控制比。它适用于电子或机械的气体/空气比率控制系统。
该阀可确保燃烧器容量的精确调节。
它由一个三点步进控制器来驱动，对于RV..E / RVS..E，则由一个连续信号（例如4 – 20 mA）来驱动。 RV..E / RVS..E具有电子定位控制，可确保较高的控制精度。
在整个控制范围内，输入信号与流量之间的比率在很大程度上是线性的。
最小和最大流速使用两个无限可调的开关凸轮进行调节。可通过两个浮动辅助开关检查中间位置或激活外部设备。
The control valve RV is designed for regulating flow rates for modulating-controlled combustion processes on gas and air appliances which require a large control ratio of up to 100:1. It is suitable for use in electronic or mechanical gas/air ratio control systems.
The valve ensures exact adjustment of the burner capacity.
It is actuated by a three-point step controller or, in the case of the RV..E/RVS..E, by a continuous signal (e.g. 4 – 20 mA). The RV..E/RVS..E features electronic positioning control which ensures high control accuracy.
The ratio between the input signal and the flow rate is largely linear over the entire control range.
The minimum and maximum flow rates are adjusted using two infinitely adjustable switching cams. Intermediate positions can be checked or external devices can be activated via two floating auxiliary switches.
