BESI Marine Systems GmbH produces reliable and robust hydraulic single-acting spring return actuators.
The HSTP-F actuator may be installed in any place - submerged in medium, in dry spaces, on deck, or in hazardous areas.
The valve position is determined by limit switches mounted externally on the actuator, or by volume transmitters installed inside the central control unit, such as the solenoid valve cabinet. The BESI volume transmitters are accepted by all major classification societies and are type-approved by Germanischer Lloyd (GL). They provide an inexpensive but very precise and reliable signal transmission and eliminate the need for any electric cabling to the valves. This ensures economic installation even in hazardous areas of a ship.
As a unique safety feature, the actuator provides a second independent piston for manual operation. It allows an emergency operation to be undertaken completely independent from the hydraulic circuit ? important in situations where the hydraulic circuit may be defective. For manual operation, a portable hand-pump can be connected to the actuator via a quick connector coupling.
