ABSTRACT:
A bleed valve for bleeding fluid from a hydraulic circuit comprises a valve body having a valve passage therethrough adapted for fluid communication with the hydraulic circuit, a valve seat on the valve body, and a sealing assembly. The sealing assembly has a valve closure connected to a valve stem and adapted for sealing engagement with the valve seat. The sealing assembly is moveable between a closed sealing position in which the valve closure sealingly engages the valve seat to block fluid flow through the valve passage and an open position in which the valve closure is spaced from the valve seat to permit fluid flow through the valve passage. A valve fitting on the valve body has an outlet port for exhausting fluid from the valve passage. The fitting is moveable relative to the valve body for selectively positioning the outlet port with respect to the valve body. The outlet port is in fluid communication with the valve passage regardless of its relative position with respect to the valve body.
