20090145294 | Ring Sealed Diaphragm - A diaphragm actuator for a fluid process control device comprises a housing, a diaphragm, a stem, and a plate assembly. The plate assembly includes a concave plate and a convex plate, each having inner and outer radial portions. The outer radial portions compressingly engage and retain the diaphragm. The inner radial portions are compressed together onto the stem between a shoulder of the stem and a nut threaded onto the stem. Accordingly, the concave plate forcibly engages and provides a fluid-tight seal directly with the shoulder of the stem without requiring an o-ring or any other additional sealing component. Moreover, the concave and convex plates are structurally equivalent such that the actuator may easily be switched between a biased-open configuration and a biased-closed configuration. | 06-11-2009 |
20100327207 | BIASING APPARATUS FOR USE WITH ACTUATORS - Biasing apparatus for use with actuators are described. A biasing apparatus for use with a piston actuator includes a first sleeve at least partially surrounded by and movably coupled to a second sleeve. Additionally, the biasing apparatus includes a stop to limit an amount of movement of the first sleeve relative to the second sleeve and a biasing element positioned between first and second ends of the respective first and second sleeves to urge the first sleeve away from the second sleeve. | 12-30-2010 |

20080197307 | VALVE FLOW ADJUSTMENT DEVICE - A valve with a flow adjustment device in the form of a valve stem travel limiter includes a removable and reversible collar having a passage therethrough to receive a valve stem having a shoulder, the passage further includes two bores having different diameters. The flow adjustment device may be assembled to a valve stem to permit two different predetermined valve stem travel limits. | 08-21-2008 |
20080197310 | VALVE FLOW ADJUSTMENT DEVICE - A valve with a flow adjustment device in the form of a valve stem travel limiter includes a collar having a passage therethrough to receive a valve stem having a projection, the collar further includes a plurality of grooves having different depths. The flow adjustment device may be assembled to a valve stem to permit a plurality of different predetermined valve stem travel limits corresponding to respective different maximum flow capacities of the valve. | 08-21-2008 |
20100193715 | MANUAL OVERRIDE APPARATUS FOR LINEAR ACTUATORS - Apparatus for manual override operation of a linear actuator are described. An example manual override apparatus includes a manual operator having a first coupling on a first side and a second coupling on a second side opposite the first side. A first drive member having external threads is coupled to a housing of an actuator. The first drive member includes a first end to removably receive the first coupling of the manual operator, a second end to selectively engage an actuation member of the actuator, and a bore therethrough along a longitudinal axis of the first drive member. A second drive member disposed in the bore to be rotatably coupled to the first drive member. The second drive member has a first end threadably coupled to an actuator stem of the actuation member and a second end to removably receive the second coupling of the manual operator. Rotation of the first drive member in a first rotational direction via the manual operator moves the actuation member of the actuator in a first linear direction and rotation of the second drive member relative to the first drive member in the first rotational direction via the manual operator causes the actuation member to move in a second linear direction opposite the first linear direction. | 08-05-2010 |
