ABSTRACT:
A low emission fluid disconnect 10 is provided along a flexible flow line 12 for transmitting fluid from the transport 16 to a bulkhead 14. The disconnect includes a ball valve 32 including a ball 31 rotated between the opened and the closed positions about a stem axis. The disconnect also includes union housing 64 and a female body 58 for threaded engagement with the ball valve. A poppet sleeve 82 is linearly moveable within the union housing between the opened and closed positions, and has an end surface 104 substantially conforming to an exterior surface of the ball. The poppet member is guided when moving between the opened and closed positions. A very low volume of fluid is released when the union housing is disconnected from the ball valve.
