In order to make it possible to increase a diameter and output thereof, a diaphragm structure is provided that has low repulsiveness, can be largely deformed to increase a stroke even without being applied with a large force from an actuator, and is unlikely to give rise to a defect or fault even when formed thin, and a fluid control valve is provided with the diaphragm structure and the actuator that presses the diaphragm structure, wherein the diaphragm structure is provided with: a protruding part that is formed in a tubular shape and pressed by the actuator; a brim part that spreads from a base end of the protruding part outward with respect to the protruding part; and a support part that is formed on an outer circumference of the brim part and attached to another member, and the brim part is formed in a film shape.

A GLV-gas lift valve that uses dual “Fortress™” seals on both sides of the bellow 19 to protect said bellow from both high dome pressure 3 acting against outside bellow surface and high injection pressure acting against bellow 19 internal surface. When valve is in closed position, after dome pressure 3 is applied, upper-dome side “Fortress™” seal is engaged and prevents high dome pressure reaching said bellow 19 external surface. When valve is in fully open position, when injection pressure 14 is applied, lower seal 10 is engaged and prevents access of high injection pressure into bellow acting against bellow internal surface. This principle allows much higher pressures to be applied in valve dome section and injection section by reducing differential pressure across the bellow 19. In addition, lower “Fortress™” seal allows very high injection pressure 14 more than 10 KSI to be applied without damage to bellow or gas lift valve components.

A GLV-gas lift valve that employs TSMS-two simultaneous mechanical stops, first one when SEWB-single edge welded bellow 8 is fully compressed to solid by valve dome pressure 5 and second mechanical stop where adjustable sealing arrangement with compressible seal 25, threaded regulating nut 17 and threaded jam nut 18 are compressed against orifice 15, compressible seal 25 is fully compressed into groove 30, gap 26 is fully exhausted, dimension L reaches zero, and gap 31 is completely exhausted, providing second mechanical stop between TC ball 14 and orifice 15. Sealing arrangement can be TC-Tungsten carbide ball 14 butted against orifice 15, flat, conical or curved sealing surface containing said compressible seal, that is solidly compressed against SEWB or DEWB, thus providing second mechanical stop and sealing fluid flow through GLV. Compressing SEWB/DEWB to full solid protects bellow from high dome pressure 5 while “Fortress Seal™” per U.S. Pat. No. 11,424,732 B2 protects bellow from high injection pressure.

A rotary valve may be operated by automated means and permits aseptic coupling of a source fluid conduit to any of a few or many possible outlet conduits. The valve assembly may be provided with numerous connectors for output coupling but it is not necessary to connect tubing to all of them.

A device for influencing the volume flow of a filling product in a filling plant for filling with filling products includes a valve body with a valve seat and a valve cone which can be displaced relative to the valve seat, an actuator for positioning the valve cone relative to the valve seat, an electronic controller for controlling the actuator, and a housing which is directly connected to the valve body and in which the actuator and the electronic controller are disposed. An arrangement for reducing a heat input into the electronic controller is provided.

A regulator performing fluid control includes an annular protruding portion having a valve seat on its leading end and an annular diameter-decreasing surface formed by decreasing an inner diameter of the annular protruding portion toward a valve hole. The regulator includes a valve element provided with a contact surface to be in contact with the valve seat and a columnar step portion provided on an inner peripheral side of the valve seat protruding from the contact surface toward the valve hole, the step portion having a diameter larger than an inner diameter of the valve hole and being coaxially formed with the valve hole. An annular ridge is formed by an outer peripheral surface of the step portion intersecting an end face of the step portion on the valve-hole side with the annular diameter-decreasing surface to constitute a passage narrowing portion.

A flow rate control valve has a waterproof function of a driving motor. The flow rate control valve is for transferring a fluid pumped by a water supply pump to a nozzle unit and a nozzle cleaning unit for cleaning the nozzle unit. The flow rate control valve includes al least one housing in which the fluid pumped by the water supply pump is accommodated, and at least one driving motor configured to change a communication area of each of the at least one housing, the nozzle unit, and the nozzle cleaning unit by rotation. At least one sealing adapter is formed between the at least one housing and the at least one driving motor so as to prevent the fluid from flowing into the at least one driving motor.

A gaiter seal for shielding a functional element of a container-processing machine extends between parts of a working head of the container-processing machine includes axially-adjacent gaiter modules that extend along an axis and support-and-sliding elements at interfaces between adjacent gaiter modules. The support-and-sliding elements radially support and guide the first and second gaiter-modules along the functional element.
