AFQMP 2 is a self-acting flow controller with integrated control valve and with pressure actuator with adjustable spring, developed for the use in district heating / cooling systems. The controller prevents flow to exceed set max flow. Pressure actuator with adjustable spring enables adjustment of differential pressure over the control cone from 0.1 to 1 bar. Increased flows can be provided. In a combination with electrical actuators AMV(E) and ECL electronic controllers the flow and temperature can be controlled to achieve highest energy savings. AFQMP 2 has a control valve with adjustable flow limiter, connection neck for electrical actuator and a pressure actuator with one control diaphrag.
