AVQM combined with AMV(E) 13, AMV(E) 23 (SL) or AMV(E) 33 (SL) has been approved according to DIN AVQM is a self-acting flow controller with integrated control valve developed for the use in district heating / cooling systems. The controller prevents flow to exceed set max flow. In a combination with electrical actuators AMV(E) and ECL electronic controllers the flow and temperature can be controlled to achieve highest energy savings. Main data: DN -32 k VS m 3 /h Flow range m 3 /h PN 16 Differential pressure over control valve Δp MCV 0.2 bar Temperature: Circulation water / glycolic water up to 30 % 2 0 C Connections: Ext. thread (weld-on, thread and flange tailpieces) AVQM has a control valve with adjustable flow limiter, connection neck for electrical actuator and a pressure actuator with one control diaphragm. Ordering AVQM Controller Example: Flow controller with integrated control valvefor flow rate 0.7 m 3 /h; PN 16; T max 0 C; ext. thread - 1 AVQM DN controller Code No: 003H6735 Option: - 1 Weld-on tailpieces Code No: 003H6908 The controller will be delivered completely assembled, inclusive impulse tube between valve and actuator.

Actuator 10. Control diaphragm 11. Union nut 12. Impulse tube 13. Compression fitting for impulse tube 14. Excess pressure safety valve Function Flow volume causes pressure drop across the adjustable flow restrictor. Resulting pressures are being transferred through the impulse tubes and/or control drain in the actuator stem to the actuator chambers and act on control diaphragm for flow control. The flow restrictor diff. pressure is controlled and limited by means of built-in spring for flow control. Control valve closes on rising differential pressure and opens on falling differential pressure to control max flow. Additionally the electrical actuator will operate from zero to set max. flow according to the load. Controller is equipped with excess pressure safety valve, which protects control diaphragm for flow control from too high differential pressure. Settings Max flow limiting Max flow limiting is being done by the adjustment of the flow restrictor position. The adjustment can be performed on the basis of flow adjustment diagram (see relevant instructions) and / or by the means of heat meter. VD.DB.V7.02 Danfoss
