Question 1

Gas Blending

Accepted Answer

Our QKL electronic proportional pressure regulator ( I/P converter) products help with gas blending applications that need repeatable pressure control. By controlling the pressure of each specific gas to a process, a tailored blend can be achieved. Here two QKL proportional pressure regulator ( I/P converter) are controlling the pressure of two types of media in a gas blending application. Our proportional pressure regulator can also work in tandem with the proportional flow control valve to stabilise the inlet air pressure, and thus stabilise the flow rate after the flow control valve.
