    摘要： A valve apparatus for use in industrial plants and systems. The valve apparatus can a first ball valve, a second ball valve, a third ball valve, and a fourth ball valve disposed between first and second blocks. A bleed valve assembly is disposed between the first ball valve and the second ball valve, and the fourth ball valve is disposed between the second and third ball valves. The bleed valve assembly is configured with threads or a cam lock for connection to a flex hose. The bleed valve assembly can include a globe valve. The valve apparatus can be implemented as a DBB (Double-Block and Bleed) valve assembly that includes the first, second, third, and fourth ball valves. The fourth ball valve disposed between the second and third ball valves can function as an extra bleed valve.

    摘要： A valve actuator for moving a valve element includes an actuator body, an opening piston, a closing piston, a first lost-motion link, and a second lost-motion link. The actuator body has an inner surface, a vent opening, a full-open pneumatic passageway, and a full-closed pneumatic passageway. The opening piston is movably disposed within the piston chamber between the vent opening and the full-open pneumatic passageway. The closing piston is movably disposed within the piston chamber between vent opening and the full-closed pneumatic passageway. The first lost-motion link is coupled to the opening piston and is operable to selectively rotate the valve element. The second lost-motion link is coupled to the closing piston and is operable to selectively rotate the valve element.

    摘要： The invention relates to a drainage connector (1) having a cup-shaped housing (2) which comprises a housing base (3) and a housing wall (4). A connection geometry (5) is arranged on the outside on the housing wall (4) for inserting into a container opening, wherein an inlet pipe (9) of an inlet side (7) is guided to an outlet side (8) through the housing base (3) and an annular collecting chamber (10) is formed between the inlet pipe (9) and the housing wall (4). In order to discharge denser fluid which can accumulate in the collecting chamber, the housing (2) has a discharge channel (11), which leads from the collecting chamber (10) to the outlet side (8) and can be closed from the outlet side (8). The drainage connector is intended to be producible in a cost-effective manner at low cost and to have a low mass. For this purpose, the inlet pipe (9) on the outlet side (8) merges into an outlet pipe (13) which has a closing element (16) that can be moved between an open position and a closed position, wherein the housing (2) comprising the connection geometry (5), the inlet pipe (9) and the outlet pipe (13) is formed from plastic as a single piece.
