Patent number: 9400057Abstract: A rotationally adjustable valve is disclosed whereby the user is able to control the flow of fluids from complete shutoff to maximum flow by rotating the body of the valve, said rotation being axial to the flow of the fluid. Additionally, the user is able to attach high and low pressure test probes directly to the valve, as it is rotatably adjusted, so that additional equipment is not required next to the valve. An embodiment of this invention includes the use of an adjustable Cv disk to set the maximum flow of the valve, rather than just create a simple 180° on/off, very similar to a current 90° ball valve that this device will replace. All of the problems associated with the ball valve have been minimized including creating a linear relationship between the percentage open of the valve and the percentage of maximum flow of the valve.Type: GrantFiled: April 2, 2014Date of Patent: July 26, 2016Assignee: Griswold Controls, LLCInventors: Stefan Tuineag, Bryan Holloway

Patent number: 9400058Abstract: A part of an air tube having flexibility is surrounded by a casing, and the air tube inside the easing is pushed for deformation at a nearly right angle against the pipe axis by a male screw screwed to a female screw of the casing to change a cross sectional area of a passage inside the air tube. A first casing part and a second casing part are overlapped with each other, and openably connected by a hinge, and the overlap state of both the casing parts and is maintained by engaging a claw part with the hole. Opposite surfaces and of both the casing parts and are provided with support grooves and for supporting the outer peripheral surface of the air tube.Type: GrantFiled: October 18, 2012Date of Patent: July 26, 2016Assignee: AUTO-NIKKINENInventor: Antero Nikkinen

Patent number: 9400059Abstract: A tube constriction valve has a valve body (1) with an approximation sensor (3) and a clamping bolt (2) that squeezes the tube inside the valve body (1). The approximation sensor (3) detects the position of the tube constriction valve and can indicate corresponding data by an approximation element (4) on the clamping bolt (2). The tube constriction valve allows for automatic and also manual operation and at the same time contains a position indicator. Consequently, damage to the tube is prevented and processing reliability preserved.Type: GrantFiled: January 27, 2011Date of Patent: July 26, 2016Assignee: SARTORIUS STEDIM BIOTECH GMBHInventor: Rolf Matthiesen

Patent number: 9400061Abstract: Fluid valve apparatus having enclosed seals are disclosed. An example fluid valve includes a movable flow control member positioned between an inlet and an outlet of a fluid flow passageway of the fluid valve. A retainer is removably coupled to the flow control member such that the retainer and the flow control member define a sealing cavity when the retainer is coupled to the flow control member. A seal is positioned within the sealing cavity to define a sealing surface of the flow control member. The seal has an inner core composed of a first material, where the core is substantially encased with a sheath composed of a second material different than the first material. The retainer clamps the seal to the flow control member.Type: GrantFiled: July 29, 2013Date of Patent: July 26, 2016Assignee: FISHER CONTROLS INTERNATIONAL LLCInventor: David John Koester

Patent number: 9400062Abstract: A thermoelement and a thermovalve incorporating the same, in which reliable operation is achieved with a simple internal structure, and there is no risk of contaminant jamming. The thermoelement includes a casing, a mounting portion, a shaft, a heat-sensitive medium, and a seal member for drawing the shaft into the casing when the heat-sensitive medium expands. The thermovalve includes a body including a valve body linked to a shaft of a thermoelement, and a seating part on/from which the valve body can be seated/separated.Type: GrantFiled: October 31, 2013Date of Patent: July 26, 2016Assignee: SMC CORPORATIONInventors: Yoshihiro Fukano, Takayuki Murai, Hikaru Tsuyuki

Patent number: 9400063Abstract: A hydraulic control valve actuated by a diaphragm's integral spring whose thicker part acts with greater force to close the diaphragm and plug unit of the valve and whose thinner part may complete the closing motion so that the integral spring may weaken faster than linearly in relation to displacement of the diaphragm and plug unit. A snap seat supporting the plug may include a seat portion and a grip skirt portion integrally joined at an acute angle. A bracket and sliding guide may guide a helical rotor touching an indicator. Movement of the diaphragm and plug unit may rotate the helical rotor and the indicator without the indicator rising out of the valve. The cover may have an internal control passage in communication with a base of the valve to allow the cover to be installed horizontally and vertically conveniently and without disconnecting the control tubing above the valve.Type: GrantFiled: April 21, 2013Date of Patent: July 26, 2016Assignee: BERMAD CS LTD.Inventor: Zvi Weingarten
