| 20090184276 | APPARATUS TO BIAS VALVE CLOSURE MEMBERS - Apparatus to bias valve closure members are described. An example biasing apparatus includes a first spring seat that has a first seating surface and a first protruding member extending a predetermined distance from the first seating surface and a second spring seat that has a second seating surface and a second protruding member extending a predetermined distance from the second seating surface. The first and second protruding members engage to slidably couple the first and the second spring seats. | 07-23-2009 |
| 20090321674 | AUTOMATED BALL VALVE AND ACTUATOR - A ball valve and ball valve actuator including a unique valve stem seal and mounting connection between the ball valve and actuator. The stem seal design reduces leakage issues and significantly lengthens the life span of the ball valve and actuator and the mounting connection between the actuator. The ball valve maintains the centrality of the valve stem in connection with the actuator pinion and minimizes torque and shear forces transferred to the valve stem and hence the stem seal itself. | 12-31-2009 |
| 20110180738 | ROTARY VALVE APPARATUS - A rotary valve apparatus includes a casing having a fluid passageway, a rotor rotatably mounted in the casing and configured to control, by rotation thereof, a flow state of fluid flowing in the fluid passageway, a drive mechanism for rotating the rotor, and a lock mechanism configured to allow transmission of a rotational force from the drive mechanism to the rotor and to inhibit rotation of the rotor under non-rotation driving state of the driving mechanism. | 07-28-2011 |
| 20120298901 | Ball Valve - A ball valve includes a first ball clamping assembly that defines a first seat surface in contact with an exterior of the ball. A second ball clamping assembly defines a second, sealing seat surface in contact with and adapted to seal with the exterior of the ball. The second ball clamping assembly is coupled to the first ball clamping assembly to clamp the ball between the first and second seat surfaces. The second ball clamping assembly includes a seat ring holder and a seat ring carried by the seat ring holder. The seat ring of the second ball clamping assembly has a sealing seat surface. A springing member is provided between the seat ring and the seat ring holder and springingly biases the seat ring toward the ball. The seat ring holder has a shoulder that supports the seat ring against fully compressing the springing member. | 11-29-2012 |
| 20120313025 | FLUID CONTROL VALVE - An actuator unit | 12-13-2012 |
| 20130026406 | VALVE DEVICE - The on-off valve includes a body having a fluid path, a spherical valve body opening and closing the fluid path, a guide member opposing the valve body and having a flange portion radially extending outward, a first seat member slidable along an outer peripheral surface of the guide member and seating the valve body, an O-ring disposed between the first seat member and the guide member, a chamber formed of an inner wall portion of the fluid path, the outer peripheral surface, the flange portion, and the first seat member, and a spring member disposed in the chamber and urging the first seat member toward the valve body. In the on-off valve, a gap portion is formed between the inner wall portion and the first seat member and connects the valve body side of the fluid path to the chamber. | 01-31-2013 |
| 20140264126 | Reduced Wear Valve - A reduced wear single input valve includes a valve stem that has a first end and a distal end, and a valve housing that has an input port and an output port. The valve stem pass through a seal interfaced to valve housing at the output port side. A valve seat is within the valve housing has one side in fluid communication with the output port and an opposing side in fluid communication with the input port. A ball is urged against the valve seat by a force of a resilient member, thereby preventing flow of fluid from the input port through the valve seat and to the output port until an opposing force is applied on the ball by the valve stem, thereby counteracting the force of the resilient member. The valve stem is isolated from a pressure from the input port while the ball is seated. | 09-18-2014 |
