1. Introduction

The 3/2-way valves are designed for applications
in high-pressure humidication and adiabatic
cooling systems.
Each valve has an IN, OUT and DRAIN port.
When the valve is not in operation the connec­tion between IN and OUT is closed while the
connection between OUT and DRAIN stays
open. This allows to instantanously relief the
pressure at shut down from the application,
typically a nozzle branch, to prevent the nozzle
from dripping. If desired, the nozzle branch can
be entirely drained after shut down to avoid
bacterial growth. Furthermore, each valve has its
individual properties to match exactly the
specic needs in size and functionality.

All of our valves are made of stainless steel (AISI

304) and are suitable for potable and technical
water. They have an extremely long service life for
at least one million operations and are even then
very easy to service.

Inline valves are available with European BSP
thread (G-thread) and American National Pipe
Thread (NPT). For the VDHT 15EC Danfoss oers a
wide range of single and multiple manifolds.

The enclosure rating is IP67, including any
standard coil. A large variety of coils for various
supply voltages is available for all our valves.

2. Overview

VDHT 2E for small ows

VDHT 15E for medium ows

VDHT 15EC Cetop 3

The VDHT 2E is a small valve for minor ow rates
up to 2 litres per minute (0.52 gpm).
It is a direct operated valve with one NO and NC
armature.
The VDHT 2E requires 2 coils activated by a
common signal (ie. 24V a.c.).
It is suitable for systems with many zones with
few nozzles and is a very cost eective solution.

The VDHT 15E is a medium size single inline valve
for ow rates up to 15 litres per minute (4 gpm).
It is comprising a piston type NC valve and a NO
pilot stage in one housing. The NO part has a
relative small orice, so it cannot drain a big
volume very fast.
It covers a very wide ow range already starting
from 1 litre per minute (0.26 gpm).
The VDHT 15E requires 2 coils activated by
acommon signal (ie. 24 V a.c.)

The VDHT 15EC 3/2 is the Cetop 3 variant of the
VDHT 15E, by means that connections are made
through a valve block or multiple vave manifolds.
In multiple valve applicatons up to 5 valves can
be installed on a common manifold side by side,
saving time, space and plumbing eort.

Sub-base valve manifolds

Danfoss oers sub-base manifolds for installin 3,
4 or 5 VDHT 3/2 way valves side by side.
The sub-base manifolds represent a very
cost-eective solution, saving signicantly on
time, space and plumbing eorts, as the number
of connections is minimized.
