Pressure independent control valve with integrated flow limiter AFQMP 2 - return and flow mounting, adjustable setting
Description
virtus.danfoss.com
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 limiter, connection neck for electrical actuator and a pressure actuator with one control diaphragm.
Controllers are used together with Danfoss electrical actuators:

Function Flow control
No. of revolutions
Flow control cone adjusts the flow by opening and closing. This action is provided by an electric actuator. The max flow is limited by limiting the maximal opening of the flow control cone. This is done by rotating the flow limitation nut. The pressure independent flow control is achieved by maintaining a constant differential pressure over the flow control cone. The differential pressure over the flow control cone is lead to the pressure actuator diaphragm through the impulse tubes. It is factory preset. The opening/closing of the pressure control cone is performed by changing differential pressure over the diaphragm. When differential pressure over the flow control cone: a) rises, the pressure control cone takes over the exceeded differential pressure by closing, until set differential pressure over the flow control cone is reached. b) drops, the pressure control cone compensates the missing differential pressure by opening, until set differential pressure over the flow control cone is reached. Pressure actuator diaphragm is equipped with excess pressure safety valve to protect diaphragm from the damages caused by too high differential pressure.
