is born in 1935 as flexible metal hose manufacturer.
As described by “Our hystory” in other section of this web site, few
years later Ultraflex starts to produce push pull cables.
Who has been following our growth and technical development along the past
time might think to an ideal path, or to a marine wake which starting from
mechanical control cables has later widened to mechanical controls, steering
helms and wheels, hydraulic steering systems and recently to electronic
During roughly 70 years Ultraflex has been extending its range of products
in order to meet our customers’ demand and most of all always aiming to
improve our quality through a constant rise in designing, R&D efforts,
new production systems and a better customer assistance, since we are fully
aware that all the people who love boating wish to use reliable products
having performances according to their expectations.
Therefore we will maintain our helm straight keeping on investing in quality
and innovation and we are sure you will want to follow our ideal marine wake
with us for many years to go.
HYDRAULIC STEERING SYSTEMS
All the components of Ultraflex hydraulic steering systems are
made specifically for the marine environment, using materials and working
process which offer long life and safety for the most extreme conditions.
A HYDRAULIC STEERING SYSTEM WORKS
hydraulic steering system consists of a steering pump, a cylinder tied to
the rudder or to the outboard or sterndrive engine and the connecting nylon
or copper tubing.
Under normal operating conditions, a turn of the steering wheel will send
the oil from the helm unit into one of the two connecting hydraulic lines.
The oil will be pumped into one of the chambers of the cylinder and either
extend or retract the cylinder rod, depending on the steering wheel
The fluid going out from the other chamber of the cylinder is returned to
the helm via the other hydraulic line.
There are two basic components in all the hydraulic steering systems: the
helm unit and the cylinder, connected by nylon or copper tubing.The helm
unit consists of both a hydraulic pump and a valve assembly.
The valve assembly prevents outgoing fluid from returning along the same
line, isolates each steering station, locks the rudder and eliminates rudder
“feedback” to the helm.
The cylinders are double acting and may be balanced or unbalanced, (in which
case the rod extends through only one end of the cylinder).
AND WARNINGS WHEN SELECTING AN HYDRAULIC STEERING SYSTEM
strength required to drive a boat equipped with an hydraulic steering system
is inversely proportional to the number of turns of the wheel lock-to-lock.
The wheel turns are determinated by the ratio between the cylinder volume,
pump displacement and the free movement of the rudder.
With the same type of cylinder installed on the engine, the less are the
turns, the faster is the response but higher is the effort; more wheel
turns, slower is the response and lower is the effort.
Other factors that can influence steering effort are:
dimension, or engine power|
type (displacement, planing, etc.)|
