A lubricator-retainer valve comprising: a body having a flowway therethrough; a valve actuator in sliding sealing engagement with said body; resilient means urging said actuator toward a first position;MUD VALVES a piston on said actuator in sliding sealing engagement with said body and providing part of a control fluid chamber exposed to pressure fluid from a control line connector which when pressurized urges said actuator to a second position; Safety valves a floating valve seat carried by said actuator; a traveling ball valve member carried by said actuator and cooperable with said seat to control flow through said flowway; trunions carried by said body and eccentrically engaging said ball valve member to rotate the ball valve member between open and closed position as said actuator moves between said first and second position; a mandrel carried by said actuator below said ball valve member and in the path of travel of the ball valve member when traveling from closed to open position;Instrument Manifolds force transmitting means between the ball valve member and mandrel; means releasably latching said mandrel to said body with the ball valve member in closed position; and pressure responsive means exposed to a second pressure fluid from a lock pressure connector for operating said releasable latching means.
