K7 Flow Control Valve offers improved flow accuracy thanks to a single piece final assembly which over comes hysteresis. The valve also has the ability to operate in both a Clock Wise (CW) or Counter Clock Wise (CCW) direction allowing it to be bi-directional.  The valve will operate with #2 fuel oil, B20 Bio-diesel, and liquid propane. The K7 Flow Control Valve comes in two body sizes 3” and 4” in diameter. There are multiple sizes within each body size. The 3” model is UL listed for #2 fuel oil and B20.
