International Classification:

G05D016/02

US Classification:

13750546, 251284

Abstract:

A pressure reducing fluid regulator having a housing with a flange including a plurality of ear-shaped protrusions is disclosed. Each of the protrusions includes at least one aperture configured to receive fastener such that the circumferential spacing between first and second fasteners is less than the circumferential spacing between the second fastener and a third fastener. The regulator includes a valve having a valve seat, a valve disc, a valve stem coupled to the valve disc and a valve guide that holds the valve stem. A lever having a first end coupled to the valve stem and a second end coupled to a diaphragm applies a force to the valve stem in a direction that is non-parallel to the longitudinal axis of the valve stem to cause the valve stem to frictionally engage the valve guide. The valve stem includes a stop that limits travel of the valve stem and disc toward the valve seat.

US Classification:

251214, 251258, 251263, 277375, 277523

Abstract:

Field removable bonnet assemblies for use with valves are described herein. An example field removable bonnet assembly for use with internal valves includes a body that is to be removably coupled to the internal valve. The body defines a bore that is to receive a valve packing. Additionally, the field removable bonnet assembly includes a shaft having a cam assembly that is to rotatably engage a stem of the internal valve. The shaft is rotatably coupled to the body and the shaft is at least partially positioned within the bore. Further, the field removable bonnet assembly includes a removable adjuster that is externally accessible to enable an adjustment of the removable adjuster relative to the body to change a force exerted by the valve packing on the shaft. The removable adjuster is field removable to replace or repair the valve packing.

Abstract:

Fluid flow control members for use with valves are described herein. An example fluid flow control member for use with a valve includes a body having a first seating surface to control a flow of fluid through the valve. The body defines a second seating surface opposite the first seating surface to control a flow of fluid through the valve. Additionally, the body defines an aperture to receive a stem of the valve, and a bore surrounded by the first seating surface to receive at least one of a seal or a sliding member each of which have a first surface to be engaged by a second surface of a spring seat coupled to the stem to control a fluid flow through the valve.

US Classification:

251 58, 251 61, 251263, 137460, 137496, 137498

Abstract:

An apparatus for operating a device such as a self-closing internal valve is disclosed. The apparatus includes a housing assembly having an internal chamber, a fluid inlet in fluid communication with the internal chamber, and an actuator stem extending from the housing assembly. The actuator stem is moveable in response to the addition or removal of a fluid into or out of the internal chamber. To control the flow rate of a fluid into and out of the internal chamber, the apparatus includes a fluid control valve in fluid communication with the fluid inlet of the housing assembly, wherein the fluid control valve is adapted to restrict the rate of fluid flow into the internal chamber of the housing assembly.

US Classification:

137490, 137221, 137460, 13763015

Abstract:

Internal valve apparatus are described. An example internal valve includes a body having a valve seat disposed between an inlet and an outlet. A flow control member operatively coupled to the body moves between a first position in which the flow control member engages the valve seat to restrict the flow of fluid through the valve and a second position in which the flow control member is spaced from the valve seat to allow the flow of fluid through the valve. The example internal valve further includes a removable actuation member disposed within the body and responsive to a fluid pressure to cause the flow control member to move between the first and second positions.
