摘要： A pinch valve assembly has opposing pinch members for pinching oppositely against a fluid conduit sleeve and a hydraulic displacement mechanism acting on the opposing pinch members. The hydraulic displacement mechanism a hydraulic displacement push rod coupled to a first pinch member at one end and penetrating a hydraulic reservoir at an opposite end to displace hydraulic fluid therein and a pinch member push rod penetrating the hydraulic reservoir at one end and coupled to a second pinch members at an opposite end. As the first pinch member moves towards the sleeve to pinch against one side of the sleeve, the at least one hydraulic displacement push rod moves into the hydraulic reservoir to displace hydraulic fluid therein to cause the pinch member push rod to be pushed from the hydraulic reservoir under pressure to push against the second pinch member to pinch against an opposite side of the valve.

摘要： An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.

摘要： The invention relates to valve system for controlling a process fluid within a liquid processing system. The valve system comprises a valve arrangement, a pneumatic or hydraulic control system, and a connector unit. When the valve arrangement is connected to the connector unit, two or more valves are formed, such that the pneumatic or hydraulic control system controls an open/close or pressure control mode of the valves. A pump diaphragm system is disclosed, as well as a system for purifying a biological material that comprises the valve system or the pump diaphragm system. Also discloses are methods of using the valve system or the pump diaphragm system in a process for the purification of a biological material.

摘要： A vacuum-based energy-saving large-capacity precision pressure regulation valve includes a base valve seat, a middle valve seat, and a pressure regulation seat. The base valve seat includes a main channel that receives a primary-side pressure and a secondary-side pressure to flow therein and includes a valve port piston arranged in the base valve seat to form a valve port opening. The valve port piston is rotatably coupled to a sealing straight rod that is coupled to a main diaphragm. The main diaphragm is clamped between the middle valve seat and the base valve seat to form a vacuum pressure chamber. A balance diaphragm is clamped between the middle valve seat and the pressure regulation seat. An atmosphere passage is connected to a space below the balance diaphragm. A guide passage and a feedback passage are in communication with the vacuum pressure chamber and the main channel.

摘要： A pinch valve has an upper casing support the entire pinch assembly and the lower casing. In a particular embodiment, a quarter-turn actuator is deployed and the sleeve may be removed without moving the actuator. The body may be open or closed to retain an external air pressure used to help close the sleeve and reduce actuator forces.

摘要： An apparatus for optical in-situ gas analysis includes: a housing; a measuring lance a first end connected to the housing and a second end projecting into the gas to be measured; a light transmitter that is arranged in the housing and whose light is conducted into the measuring lance and is reflected by a reflector arranged at the second end onto a light receiver, and the optical path defines an optical measurement path within the measuring lance; and, an evaluation device for evaluating received light signals of the light receiver. In order to be able to reduce the consumption of test gas, the measuring lance has an outer tube, with the outer tube having openings for the gas to be measured. The openings can be closed by at least one seal for the test phase, with the seal searingly closing the openings by the enlargement of its volume.
