KG S Y S T EM I N F O RMAT I O N Hydraulic Spring Return Actuator (Type HSTP – F) C O N TA C T F L OW MA N A G EME N T WWW. B E S I . D E BESI Marine Systems GmbH & Co. KG produces reliable and robust hydraulic single-acting spring return actuators. Installation The HSTP-F actuator may be installed in any place - submerged in medium, in dry spaces, on deck, or in hazardous areas. Position Response 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. Emergency Operation 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.

Single-acting ¼ -turn actuators need only one hydraulic supply pipe. • Operation of high oil pressure levels of 100 up to 135 bar, and up to 160 bar on request. • Small, compact overall dimensions. • Wide range of torques. Opening torques range from 190 Nm up to 7.730 Nm and closing torques from 100 Nm to 4050 Nm.
