Abstract

An electromagnetically operable pressure-regulating valve is proposed, in whose valve connection element (40) there is configured a choke bore (57, 57a to 57c). The choke bore (57, 57a to 57c), which operates hydraulically like a choke, facilitates the balancing of the pressure-regulating valve in the hydraulic system and produces a characteristic curve of the pressure-regulating valve which is virtually temperature-independent.
