20100201118 | CONDUIT CONNECTION WITH SENSING FUNCTION - Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member ( | 08-12-2010 |
20110308655 | CLAMP RING FOR WELDED DIAPHRAGMS - A diaphragm sealed flow cavity comprises a first body comprising a support surface, a diaphragm comprising an outer portion that is joined by a weld to the first body, a clamped portion, and an inner portion that is movable along an axis, with the clamped portion of the diaphragm being compressed between the bearing surface and the support surface. The diaphragm sealed flow cavity may include a cylindrical body having a crimped portion for joining the cylindrical body to the first body. The diaphragm sealed flow cavity may also include a member that applies a live load to the clamped portion of the diaphragm. In the exemplary embodiments, the diaphragm sealed flow cavity may be realized as part of a diaphragm flow control valve having a valve body, diaphragm and a housing. | 12-22-2011 |
20130214192 | COATED SEALS - The seal made between two surfaces is enhanced by forming a coating, such as a self-assembled monolayer of a functionalized fluorinated macromolecule, on one or both of the surfaces. | 08-22-2013 |
20130270814 | CONDUIT CONNECTION WITH SENSING FUNCTION - Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member, a drive member, and a seal member, the drive member causing axial movement of the conduit gripping member to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member causing the seal member to form a zero clearance seal at a location that is axially spaced from the conduit gripping member. The zero clearance seal may comprise a face seal arrangement including a gasket, and the conduit gripping member may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include a sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both. In one embodiment, a body coupling member has a two piece construction of a main body and a conduit socket insert. A flared fitting embodiment is also provided. Sensing functions are also incorporated into fittings other than just zero clearance fittings. | 10-17-2013 |
20140103240 | ACTUATOR WITH DUAL DRIVE - A manually operated actuator is provided with an over-travel feature. The over-travel feature may be realized with a controlled thread backlash or with a biasing member such as a Belleville spring. When used with a flow control device such as a diaphragm valve, the over-travel feature allows the valve to open and close at actuator positions other than full stop positions. Embodiments for manual actuators and hybrid actuators are presented. | 04-17-2014 |
20140130904 | ACTUATOR WITH VISUAL INDICATOR SLEEVE - A device, for example a flow control device, and actuator or both are provided with a heat shrinkable sleeve about an exterior surface of a housing for the device. The heat shrinkable sleeve may contain indicia or information relating to the device. The heat shrinkable sleeve may also be used to contain fluid and contaminants that escape from the device from exposure to an environment that is exterior the heat shrinkable sleeve. The housing may include structure that retains the heat shrinkable sleeve in an installed position. Such structure may be, for example, a recessed surface, a flange, a crimp or other structure. | 05-15-2014 |

The diaphragm sealed flow cavity may include a cylindrical body having a crimped portion for joining the cylindrical body to the first body. The diaphragm sealed flow cavity may also include a member that applies a live load to the clamped portion of the diaphragm. In the exemplary embodiments, the diaphragm sealed flow cavity may be realized as part of a diaphragm flow control valve having a valve body, diaphragm and a housing. | 07-10-2014 |
20150060708 | BELLOWS VALVE WITH VALVE BODY CYLINDER ADAPTER - A valve having a valve body with a valve cavity that receives an axially extensible member, for example, a bellows. An adapter has a diameter that is less than the diameter of the valve cavity and greater than the diameter of the extensible member, so that the adapter is disposed between the valve body and the extensible member. The adapter forms a valve body compression seal and a compression seal for the extensible member. Use of the adapter allows a common valve body to be used with different sized bellows of different lengths and diameters as needed, as well as facilitates easy installation and replacement of the bellows. | 03-05-2015 |
