CONDITIONS AND EXCLUSIONS

Ultraflex products are guaranteed against defects in material or workmanship for a period of two years following the date of manufacture.
Defective products should be returned freight prepaid to the facility and must be accompanied by an issued Returned Goods Authorization number.
Upon receipt, the product will be examined to determine the cause of defect. If the product is determined to have a defect in workmanship or material, it will be repaired or replaced at our discretion.
This guarantee does not cover labor.
This guarantee does not cover products that have been misinstalled or misapplied. Futhermore, it does not cover claims for direct or indirect damage.
We decline liability and exclude guarantee if products are improperly installed, misapplied, or misused.

Our products are not intended to be used in racing applications.
The descriptions and guidelines shown in this catalog should be used as general reference only. For any further information please contact our Technical Service.
ULTRAFLEX hydraulic steering systems components are all marked CE in compliance with the EEC Directive 94/25 and the rule ISO 10592. The CE Examination on the ULTRAFLEX steering systems has been carried out by an Institute certified by the European Commission.

We kindly remind you that on the boats marked CE it is compulsory to install steering systems with components marked CE (see art. 4 and 5 of Directive 94/25/CE).

We inform you the ULTRAFLEX guarantee is null and void if some ULTRAFLEX components are installed on a hydraulic steering system together with products of other brands, with the exception of those brands clearly specified in our cross reference below.

ULTRAFLEX 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.
HOW THE SYSTEM WORKS

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 rotation.
The fluid going out from the other chamber of the cylinder is returned to the helm via the other hydraulic line.
There are only two basic components in all the hydraulic steering systems.
These are 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).


SUGGESTIONS AND WARNINGS WHEN SELECTING AN HYDRAULIC STEERING SYSTEM

The 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:

  • Vessel speed
  • Rudder dimension, or engine power
  • Propeller selection
  • Hull type (displacement, planing, etc.)
  • Sea conditions
  • Oil viscosity
