PROPORTIONAL VALVES

HT1032/35
Proportional valve assemblies. HT1032 for one thruster
or windlass HT1035 for two thrusters or a thruster
and a windlass. These valves can be mounted on a
HT1010 tank.

HT1032 HT1035

Model HT1034 Proportional control joystick
Single joystick control.
The LED lights up when the joy-stick is opening the proportional valve.
The LED will go out when the joy-stick is in neutral.
The LED can be installed in one of the mounting holes of the joystick.

Note HT1012 two stage, load-sensing valve set is supplied standard with an HT5034 electrical junction box.

For systems not incorporating an HT1011 or HT1012 load sensing valve, the HT5034 electrical junction box must be ordered
separately, if required.
For systems including an HT1010 reservoir tank, one HT1013 on/off, directional valve is supplied standard with the tank, but
the HT1012 two stage, load-sensing valve set must still be ordered separately. If the system incorporates two thrusters with
proportional control, then an HT1035 dual valve assembly will be supplied, rather than two HT1032s.
For electronic control of any thruster, as required for integrated joystick systems, dynamic positioning/station holding
systems, etc., proportional valves must be used, with connection heads specified for electronic compliance with the output of
the electronic control system.

When a proportional valve such as the HT1032 is specified, the valve will be set up by Vetus to match the flow requirements
of the thruster or other device. Without such an adjustment, control range may be drastically reduced. Please discuss this
with your VETUS hydraulic support engineer when completing your order.
