| 137315040 | Pressure regulating type valve | 6 |
| 20090145487 | SANITARY VALVE ASSEMBLY - A reusable sanitary valve assembly with a releasable cap or cover that disengages from the valve indicating an over-pressure situation has occurred, the cap or cover is capable of being reset, and once it is known that gas, liquid or other contaminants have possibly entered the valve following an over-pressure situation, the interior of the valve can be inspected by removing a portion of the valve while the valve remains sealed on a pressurized substrate and, if the interior of the valve is contaminated, the interior of the valve can be cleaned and closed without unseating the valve. | 06-11-2009 |
| 20110186147 | REGULATION VALVE - The present invention concerns a regulating valve ( | 08-04-2011 |
| 20110272040 | QUICK RELEASE GAS PRESSURE REGULATOR - A quick release gas pressure regulator having a primary pressure zone, a secondary pressure zone, and a gas bottle connection zone within the main body. A pressure-regulating device is positioned within the secondary pressure zone of the main body. A gas chamber sealing plug is disposed at the front portion of the first pressure chamber of the main body. An external axial pressure relief passage is formed at the gas chamber plug. A positioning ring seat includes an internal axial pressure relief passage communicating with the external axial pressure relief passage. A pressure relief O-ring is positioned at the joint between the internal axial pressure relief passage and the external axial pressure relief passage. A gas supply back-up post is divided by the pressure relief O-ring into a sealing portion and a pressure relief portion. A pushing member radially passes through the main body and the positioning ring seat, and having a pushing inclination facing the internal end of the gas supply back-up post. A return spring is positioned at the internal end portion of the pushing member. An operating lever is pivotally connected to the main body. The operating lever includes a cam portion facing the external end of the pushing member. In this way, an easy detachment and an improved use safety are achieved. | 11-10-2011 |
| 20140366959 | SEAL ASSEMBLIES FOR USE WITH FLUID VALVES - Seal assemblies for use with fluid valves are described. An apparatus includes a cage, a plug having a seal gland and a seal assembly to be at least partially positioned in the seal gland. The seal assembly includes a back-up ring having a wedge-shaped protrusion and a seal defining a wedge-shaped groove to receive the protrusion. A pressure is to act on the back-up ring to urge the protrusion into the groove. An engagement between the protrusion and the groove is to urge the seal into sealing engagement with an inner surface of the cage. | 12-18-2014 |
| 137315050 | Diaphragm type | 2 |
| 20110226347 | PRESSURE REGULATOR HOUSING ASSEMBLY - A pressure regulator housing assembly includes a lower housing and an upper housing; a plunger and diaphragm assembly supported within the lower and upper housings, the plunger movable toward and away from a valve seat. The diaphragm has a radially inner edge fixed to one end of the plunger and a radially outer edge clamped between an annular surface within said upper housing and a surface of a clamp ring locked against rotation relative to said upper housing thereby isolating said diaphragm from any contact with the lower housing. Upon assembly of the upper and lower housings requiring relative rotation therebetween, an upper edge of the lower housing is engaged by a lower surface of the clamp ring. | 09-22-2011 |
| 20140020769 | QUICK CONNECT, POST ENERGIZED FLANGED JOINT FOR A DIAPHRAGM VALVE - A diaphragm valve feature a valve body having a passage that opens to allow fluid to pass, and closes to prevent fluid from passing, through the valve body; and a bonnet assembly having a pressure ring to load/unload a diaphragm depending on a first spring constant to seal a peripheral portion thereof, and a compressor to close/open the passage of the valve body. A rotational connection fixes together the valve body and bonnet assembly with a second spring constant that is higher than and independent from the first spring constant, and includes the valve body having a rim with two shouldered pins on opposite sides. The bonnet assembly has a corresponding rim with two keyways on opposite sides thereof. Each keyway is recessed to receive and engage a respective shouldered pin when the bonnet assembly is rotated relative to the valve body. | 01-23-2014 |
