| 137315170 | Assembling or disassembling rotary valve | 13 |
| 20090288714 | Valve Control Assembly - Valve control assemblies are disclosed which accommodate out of plumb conditions using a flexible set of rings linked to the temperature control, and a projection/axial slot arrangement linked to the volume control. Different wall thicknesses are accommodated using one or more adaptors/extensions between a temperature bonnet control and a portion of the valve cartridge which controls temperature. There is also a combined shroud/tool for protecting the valve during rough-in and permitting it to be tested. | 11-26-2009 |

| 20100089464 | FLYING VALVE FOR FREE PISTON - The invention relates to oil and gas production and can be used for lifting a fluid from a well by using a gas power. The inventive flying valve for a free piston comprises a tubular body, a detachable element, which is insertable therein and is embodied in a form of a solid of rotation, and an arrester used for limiting the detachable element travel. The arrester is embodied in the form of a ring, the diameter of which is less than the internal diameter of the tubular body and is arranged coaxially therein. The thickness of the walls of the annular arrester gradually increases in the direction of the detachable element and the top and lower edges thereof are rounded. The arrester can be embodied in one piece with the tubular body and connected thereto by means of one or more connecting straps. Said arrester can be also embodied in the form of a separate part provided with at least two fixing projections. The tubular body is made of a flexible elastic material and the wall thereof is provided with holes matching the shape of the fixing projections of the arrester which are insertable therein. | 04-15-2010 |
| 20100288374 | SPLIT VALVE - Valve assembly including a first and second valve components in fluid connection with respective first and second ducts, each valve component having a housing and a closure member, a first closure member having a pivot axis extending transversely to the first duct, the first closure member being pivotable between closed and open positions. The first and second closure members each have a coupling element releasably interconnecting the closure members, so the second closure member can be moved with the first closure member upon pivoting of the first closure member around the pivot axis, the second closure member including connector element for engaging with a complementary connector element on the second housing in a closed position of the second closure member, which connector element maintains the second closure member in a non-pivotable sealed attachment with the second housing when the valve components are separated. | 11-18-2010 |
| 20140026981 | BALL VALVE - A ball valve including a valve body with connection portions, one or more threaded ring-nuts screwable to the connection portions to connect them, a control handle and a ring-nut spanner tool suitable for engaging the ring-nut to screw and unscrew the ring-nuts from the connection portions. The ring-nut spanner tool is housed in a rest position in the control handle and can be moved from the rest position to a working position outside the control handle. In the working position, the ring-nut spanner tool can engage the ring-nut. | 01-30-2014 |
| 20140305518 | Oilfield Safety Valve - An improved safety valve for oilfield operations comprising a first valve body comprising: an axial bore adapted to allow fluids to pass, a first end operatively engaging pump equipment, and a second end adapted to axially compress with a second valve body; the second valve body comprising an axial bore, adapted to axially compress with a second end of an intermediate valve body connector and the second end of the first valve body, and a second end operatively engaging pump equipment; the intermediate valve body connector having an axial bore and means for axial compression with the second valve body; the axial bores of the first and second valve bodies and the intermediate connector adapted to being axially aligned when compressed; and a valve internally disposed between the first valve body and the intermediate valve body connector and the second valve body and actuated by an externally accessible torque means. | 10-16-2014 |
| 137315190 | Particular valve seat or interface seal | 3 |
| 20100229962 | Multi-component Metal Seat Design for Ball Valves - A floating ball valve has a metal multiple component seat installed in the seat pocket. The multiple component seat further includes a support ring and at least one seal element. The support ring and the seal element are juxtaposed and both are adjacent to the ball when the floating ball valve is in a closed position. The support ring is in a overlapping complimentary position with respect to the seal element, the seal element having greater elasticity than the support ring and the support ring having a greater load bearing strength than the seal element. | 09-16-2010 |
| 137315200 | Replaceable | 2 |
| 20140311589 | MULTI-PORT CONNECTOR FOR FLUID ASSEMBLIES - A multi-port connector is provided with a body having an inlet port associated with a primary outlet port and a plurality of auxiliary outlet ports. The auxiliary outlet ports may include valve systems for selective fluid engagement with a fluid source. The primary outlet port of the body is valve-free in some embodiments, allowing the connector to be coupled with additional multi-port connectors to form multi-line fluid manifolds. | 10-23-2014 |
| 137315210 | With top entry valve | 1 |
| 20090266424 | Manifold - The invention regards a manifold for fluids, comprising a housing ( | 10-29-2009 |
| 137315220 | Butterfly valve | 2 |
| 137315230 | Having valve head or seat packing | 2 |
| 20150377373 | Butterfly Valve Comprising Removable Coupling Part - A soft-sealing, concentric butterfly valve ( | 12-31-2015 |

| 137315250 | Plug valve | 2 |
| 20130220445 | PLUG VALVE WITH A SPRING BIASED PLUG - In a plug valve with a plug supported around its axis of rotation in a flow passageway of the valve housing, the plug is supported in a floating manner against a spring force pressing the plug against an annular sealing element. The spring force is provided by a spring element bearing against the valve housing and engaging with a trunnion of the plug. The sealing element is supported in a fixed position against a flow passage opening. | 08-29-2013 |
| 137315260 | Having retainer at actuator end | 1 |
| 20150101682 | Mud Valve with Integral Yoke and Flange - A mud valve having a flange frame and yoke that are permanently connected to form a single unit without the aid of removable fasteners is described. Installation of the drain plug is facilitated by an arrangement of guide tabs on either side of the drain plug that are of different distances from the surface of the drain plug. This staggered arrangement allows the drain plug to be installed through a tilting and rotating of the drain plug that brings the tabs into alignment with guide rails on the yoke without necessitating the separation of the yoke from the flange frame. Similarly, the construction described allows the drain plug to be removed for repair or replacement in the field without disassembling the yoke and flange frame. | 04-16-2015 |
