ABSTRACT:
A hydraulic valve with a housing, which is made of a plastic material, and with at least two fluid connections and a valve element arranged movably in the housing. A valve of this kind must on the one hand be able to withstand a sufficient pressure and on the other hand the production of the valve must be inexpensive. For this purpose the housing is surrounded by a metal sheet enclosure having at each fluid connection an opening, which is surrounded by a metal sheet wall projecting from and connected with the metal sheet enclosure.
