Air handling unit – heating coil

Introduction

Heating coil graphic

Typical for applications are: considerable amount of operating hours under part-load conditions; fast control action is essential (positioning time);  0-10 V control signal; 2-port or 3-port valves; flanged or threaded valves; PN 16 pressure class.

The proposed combinations vary in: control accuracy (valve characteristic, positioning time); availability of fail-safe function; amount of flow volume; input signal for frost protection; robustness.

High control quality combination

High control quality combination

Stroke valves (20/40 mm stroke) with selectable flow characteristic; (also 2-port valves VVG41 and VVF41/VVF52);  fine gradual increments in kVS-values; excellent flow control in hydraulic circuits with large volumetric flows; fail-safe function; input signal for frost protection; extended actuator functionality using accessories; robust and easy to service.

Fast and accurate flow control combination

Fast and accurate flow control combination

Magnetic 2-port/ 3-port valves: threaded or flanged with integrated actuator and selectable flow characteristic; fast and high-precision flow control in hydraulic circuits with medium volumetric flows; opening without inlet jump; excellent for minimum controllable load; fail-safe function; input signal for frost protection; long service life due to few moving parts.
