Domestic hot water (DHW) – storage tank charging

Introduction

Storage tank charging graphic

Typical for applications are: slow changes in heating demand; low pressure drop in the valves; fail-in-place behavior at power failure; 3-position control signal; 3-port flanged or threaded valves; PN 6, 10 and 16 pressure class.

The proposed combinations vary in: control performance; ability for precise selection related to kVS-values gradual increments;  price/performance ratio; PN pressure class; amount of flow volume, robustness.

High control quality combination

High control quality combination

PN 16 stroke valves (20/40 mm stroke) with selectable flow characteristic; (also 2-port valves VVG41 and VVF40); fine gradual increments in kVS-values; excellent flow control in heating circuits with large volumetric flows; robust and easy to service; extended actuator functionality using accessories; offering for different PN classes, and control signals.
