Abstract: A container (10) for receiving biopharmaceutical content (C) in liquid, fluid or gaseous form, includes a peripheral wall (12) that is closed on itself, at least one transfer pipe (22), at least one guiding element (30; 130), and wherein the at least one guiding element (30; 130) includes a gripping member (32; 132) and an attachment member (44; 144). The gripping member (32; 132) and the attachment member (44; 144) are structurally separate and independent of one another and the guiding element (30; 130) has reciprocal assembly elements (60; 160) allowing the structural or functional assembly of the gripping member (32; 132) with the attachment member (44; 144) to ensure the positioning of the gripping member (32; 132) close to the attachment member (44; 144) and the connecting area (46; 146) of the corresponding peripheral wall (12).

Abstract: A valve arrangement comprising a main valve member being axially movably arranged in a valve housing and arranged to interact with a main valve seat of the valve housing in order to restrict or regulate a pressure in a main fluid flow in response to a pilot pressure acting on the main valve member. A control valve member is axially movable within the main valve member in response to an actuating force acting on the control valve member. A pilot valve member is axially movable within the control valve member, and is arranged to interact with a pilot valve seat of the control valve member to restrict a pilot fluid flow out from a pilot chamber. The pilot valve member is resiliently loaded towards the pilot valve seat relative the main valve member or the valve housing, such that the resilient loading on the pilot valve member is adjustable in response to the actuating force.

Abstract: A valve device includes: a poppet that is formed in a hollow shaft shape except for a leading end, has a tapered closure part at the leading end and a side hole passing through a wall of the hollow shaft-shaped part, and rotates around a shaft center thereof during opening and closing actions; and a valve seat having a sloped seat surface with which the closure part of the poppet comes into contact when closing the valve device. The closure part of the poppet or the seat surface of the valve seat, whichever has a higher hardness, has a cut mark of the opposite direction from a direction of rotation of the poppet around the shaft center that occurs during the valve closing action.

Abstract: A check valve (100) has a valve seat (20), and a valve disc (30) which closes the valve seat (20) in an openable/closable manner by linear reciprocating oscillation in the direction approaching or departing away from the valve seat (20), the check valve (100) being configured, as a lift-type check valve, to allow therein the inflow direction (D1) of a fluid (F) flowing into the valve seat (20) and the passing direction (D2) of the fluid (F) passing through the valve disc (30) to cross each other, the valve disc (30) being provided with, on the inflow side (primary side) thereof, a deflection surface (40) on which the fluid (F) is deflected from the inflow direction (D1) to the passing direction (D2).

Abstract: A variable valve may include a housing having hinge support portions protruding from a first side thereof, and an opening at a second side thereof, a first gate rotatably coupled to the hinge support portions so as to open and close a part of the opening, a first spring mounted on the housing to apply elastic force in a direction in which the first gate is closed, a second gate rotatably coupled to the hinge support portions so as to open and close a remaining part of the opening, and a second spring mounted on the housing to apply elastic force in a direction in which the second gate is closed, in which the first spring and the second spring may have different spring constants.

Abstract: An embodiment provides a check valve including a valve case, a positive pressure valve having a resin ring sealing member, and a resin negative pressure valve. The positive pressure valve and the negative pressure valve are disposed in the valve case. The positive pressure valve includes a first mount surface and a second mount surface disposed on an inner diameter side of the first mount surface. In the valve case, a presser cap is mounted on the positive pressure valve so as to sandwich the ring sealing member and the negative pressure valve with the first mount surface and the second mount surface of the positive pressure valve.

Abstract: A valve arrangement comprising a valve housing, a pilot chamber, a main valve member and a control valve member. The main valve member is axially movably arranged in the valve housing and is arranged to restrict a main fluid flow. The control valve member is movable in an axial direction relative the main valve member in response to an actuating force acting on the control valve member. The control valve member is arranged to interact with the main valve member to define axially separated pilot and bypass fluid restrictions. The pilot restriction restricts a pilot fluid flow out from the pilot chamber. The bypass restriction restricts a bypass flow bypassing the main fluid flow. The bypass flow is separate from the pilot fluid flow. The pilot and bypass restrictions are adjustable in response to the actuating force, thereby allowing simultaneous adjustment of the pilot pressure and the bypass fluid flow.

Abstract: A valve unit for a motor vehicle having a valve housing, which includes a valve inlet and a valve outlet, and having a valve body disposed in the valve housing, which includes a cross-section, increasing up to an inflection point and decreasing once past the inflection point, and which is guided from a closed position in which the valve body seals the valve inlet to a final opened position in which the valve body abuts a stop element fixed in the valve housing, releasing the valve inlet, and in which an inflow section is formed between the valve inlet and the inflection point of the valve body, and an outflow section is formed between the inflection point of the valve body and the valve outlet.

Abstract: Systems and related methods for conserving various resources, such as, but not limited to, water, laundry chemicals, natural gas, electricity, linen, labor, and wear on equipment (e.g., a solenoid valve of a commercial washing machine drain line). The inventor has spent the past 14 years in the industrial chemical field, allowing him to access and service commercial washing machines, and has discovered that drain issues relative to such commercial washing machines result in enormous losses to such institutions that process a large volume of laundry. Such typical institutions include, but are not limited to, hotels, hospitals, prisons, universities, colleges, laundries, and nursing homes. By replacing a portion of the opaque drain pipe section between the valve and the floor drain, operators and technicians can quickly determine if a leak is occurring, and take corrective action. An access port may also be provided to test characteristics of discharged wash water.

Abstract: A gas flow adjusting device is provided, which includes a tube body, a first horizontal shaft, a second horizontal shaft, two leaf structures, a torsional spring and two linkage assemblies. The first and second horizontal shafts are disposed in an accommodating space of the tube body and spaced apart from each other along an axial direction of the tube body. The leaf structures are pivoted on the first horizontal shaft and have a swinging direction identical to the axial direction. The torsional spring is sleeved around the second horizontal shaft and provides a resilient force along the axial direction. The linkage assemblies are connected to the leaf structures respectively, and each of the linkage assemblies is connected to the second horizontal shaft and the torsional spring. Therefore, when the leaf structures swing to different angles, the twisting amounts of the torsional spring are minimally varied.

Abstract: A coupling part, particularly a coupling cuff, for a quick-release coupling for high-pressure hydraulic lines, has a coupling housing having a through-flow channel and a valve device disposed within the through-flow channel, this device having a tappet-like closing valve for closing off the through-flow channel in the uncoupled state of the coupling part. The coupling housing has a conical valve seat surface, and the closing valve has a longitudinal valve axis as well as a valve head having a conical surface and a valve sealing ring for sealing contact with the valve seat surface. The valve sealing ring has a circular-cylindrical ring circumference surface that projects beyond the conical surface in the radial direction and has a valve seal diameter DVD.
