3.3.2 Remote control operations
BIFFI has the ability to apply advanced engineering technology to the
design and manufacture of hydraulic controls and accessories.
The experience and the knowledge acquired in the actuator industry
allow BIFFI to meet with the highest requirements for control modes
and operating conditions by correct selection of schematics,
components, materials and protection treatment.
The actuator service can be On-Off or Modulating. Actuator control
can be local or remote by electric, or hydraulic signals.
The control system can include devices for automatic operation or
stay put in case of emergency conditions (electric or hydraulic supply
failure, high temperature, low or high pipeline pressure etc.).
The control systems have where is possible a "manifold design": the
components are connected by a flange to the manifold or assembled
into the cavities machined into the manifold. This allows to have a
very "compact" unit to reduce the number of connections by fittings
and pipes and then to make the assembly and disassembly of each
component easier, and to minimise the risk of oil leakage also in
case the system undergoes strong vibrations. Control systems can
be supplied as panel mount or enclosed into a weatherproof cabinet.
Control systems can be supplied separate or assembled onto the
actuator. The actuator housing has dedicated supports for the
mounting of control systems and accessories.
