摘要： A suction/irrigation medical device valve system comprises a first valve plunger configured for insertion into a first valve plunger channel. The first valve plunger has a first latch member disposed at a distal end with a first sealing member and a first valve opening disposed proximally from the first latch member. The system also comprises a second valve plunger configured for insertion into a second valve plunger channel. The second valve plunger includes a second valve opening that is longer than the first valve opening. The system also comprises a valve body having the first and second valve plunger channels. The first and second valve plunger channels are configured to receive the first and second valve plungers, respectively.

摘要： A pressurization and evacuation system is provided, including a top 3-way valve including a first port, a second port and a third port, a bottom 3-way valve including an first port, a second outlet port and a third port, and an educator including a pressure inlet, a suction inlet, and a discharge outlet. Wherein: a first conduit fluidically connects the top 3-way valve third port with the educator pressure inlet; a second conduit fluidically connects the top 3-way valve second port with the bottom 3-way valve first port; a third conduit fluidically connects the bottom 3-way valve third port with the educator suction inlet; and a fourth conduit fluidically connects the bottom 3-way valve second port with a customer apparatus.

摘要： A three-way valve assembly, including a valve body having a fluid flow path and a valve member movable in the fluid flow path between a supply port and a work port, and between a load sense passage and a pressure relief port. The valve member may move between a first position and a second position for controlling flow and regulating fluid pressure differences sensed in the flow path; and for limiting fluid pressure in the flow path to a predetermined pressure level set by a pilot-operated pressure limiter valve when the valve member is in the second position. The valve member may move between the second position and a third position to open the flow path from the load sense passage to the pressure relief port for relieving fluid pressure in the flow path when the fluid pressure from an over-loaded actuator exceeds the predetermined pressure level set by the pressure limiter valve.

摘要： An electrically actuated control valve has three mouths and three operating positions, in which the three mouths includes a first mouth for inlet of a working fluid, and a second mouth and a third mouth for outlet of the working fluid. The three operating positions include a first operating position in which a passage of fluid from the first mouth to the second mouth and the third mouth is enabled, a second operating position in which a passage of fluid from the first mouth to only one of said second and third mouths is enabled, and a third operating position in which the passage of fluid from the first to the second mouth and the third mouth is disabled. The control valve includes an electric or electromagnetic actuator for controlling the passage of fluid from the first mouth to the second and third mouths providing the aforesaid three operating positions.
