2. Introduction
The VDHT valve series are designed for several
applications in neutral media compatible with
the sealing and O-ring materials used. Typical
media are water, cleaning uids and light
heating oil.
The valves are used in several applications: car
wash systems, stationary high pressure cleaning, mobile cleaning vehicles and dust bindings
systems, ect.
Function
The directional valves are pilot operated ON/OFF
– seat valves electrically activated by a coil.
• Possible to get a compact and simple block
solution (Integrated valve block)
Versions
The valve housing, blocks and manifolds are
made of stainless steel AISI 304 (W.No. 1.4301),
and the piston of stainless steel AISI 316 (W.No.
1.4401). Standard valves are delivered with PTFE
piston and FKM as seal material and FPM O-rings.
VDHT inline valves are available with a number of
mounting possibilities, ow direction, port size:
3
¼,
/8, ½, ¾ and 1” BSP and more - dening the
following designation. The VDHT valves are also
available with NPT thread.
VDHT integrated valve blocks provide a space
and cost-saving solution in applications where
valves are placed next to each other. Furthermore, integrated valve blocks provide a
pressure loss reduction.

Temperature
• Medium temperature: 2–90 °C (35.6–194 °F)
• Ambient temperature: 2–80 °C (35.6–176 °F)
depending on the coil specication
• Storage temperature: -40–80 °C (-40–176 °F)
Provided that the valve is drained from uid
and stored “plugged”.

Viscosity
For correct functioning of the VDHT valves, always ensure the inlet pressure to be higher than the outlet
pressure
The VDHT pilot oprated poppet type (armature + poppet) always needs min. 1 l/min. (0.26 gpm) ow to
ensure correct functioning
Max viscosity of uid: 45mm
