Hydraulic valve body screwed into housing - incorporates counter screw to ensure good sealing

摘要

Valve body (7) for high pressure hydraulics which is screwed into a bore (2) with an inner seal (11) pressed against a shoulder (4) and an outer seal (21). The valve body at the housing surface (13) extends outwardly and a counter screw (17) separated from the valve body by a threaded connection (8) forms a closing head part (33). ADVANTAGE - Valve body assembly in which the distance between the housing contact surface and the bore shoulder is significantly reduced.
