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:

• AFQMP 2 PN 16/25/40 DN 65-250

- AMV(E) 655 without spring return function

- AMV(E) 658 SD 2) spring return function and

- AMV(E) 659 SD 1) spring return function;

- AMV(E) 55

• AFQMP 2 PN 16/25/40 DN 65 -125

- AMV(E) 56
