A pressure regulator including a housing including an inlet flow passage and an outlet flow passage; a plunger reciprocally mounted in the housing and including a plunger flow passage having an axis offset from an axis of the inlet flow passage, and a stationary valve seat fixed to the housing and positioned between the inlet flow passage and an inlet to the flow passage of the plunger, wherein the valve seat is configured to receive and abut the inlet to the flow passage of the plunger.

The invention relates to a pressure equalizing insert (1) which is provided for installation in a valve (10) for regulating a fluid stream in particular in a HVAC system. The pressure equalizing insert (1) comprises a housing (2) having an actuating member (3) which is movably mounted thereon and is configured to at least partially guide the fluid stream regulated by the valve (10) and, when the pressure equalizing insert (1) is installed, co-operates with a valve seat (15) depending upon a pressure difference prevailing in the fluid stream in order to regulate the fluid stream. The invention further relates to a valve (10) having an installed pressure equalizing insert (1), wherein the pressure equalizing insert (1) can be inserted in particular as a pre-assembled assembly into the valve (10).

A pressure regulating device for a liquid includes a main hollow body having an inlet end and an outlet end for the liquid, which are connected via a longitudinal passage, a tubular valve member, which is slidingly accommodated in the passage and has a regulating end upstream from the flow of the liquid, a seat placed inside the passage, upstream from the valve member, and having a transverse surface formed in the passage to interact with the regulating end of the valve member and define therewith a part having an adjustable width for the liquid. The seat is eccentrically supported in the passage and is formed of one piece with the main body, and is supported proximate to the inlet end for the liquid by a pair of longitudinal support wings substantially parallel to the flow direction.

An axial flow regulator includes a lateral access port through a portion of the valve body that provides access to a valve seat assembly and/or other portions of the valve trim without having to remove or uncouple the outlet flange or the inlet flange from the adjacent pipe sections. The lateral access port may extend through an outlet flange portion of the valve body and is configured to allow a valve seat assembly to be laterally inserted into and removed from the outlet flange. A valve seat assembly which may be configured for installation in the axial flow regulator includes a pad holder and a support ring for the pad holder that is separable from the pad holder. The pad holder may have alignment struts projecting radially outwardly from a pad support body. The support ring may include strut receivers that slidably receive the alignment struts of the pad holder.

A pressure regulator includes a housing having an upper housing portion and a lower housing portion, the lower housing portion defining an annular recess and the upper housing portion having a bottom surface, an annular protrusion extending from the bottom surface, a diaphragm disposed between the upper housing portion and the lower housing portion, the diaphragm including an outer lip having a first thickness, a flexible connecting section connected to the outer lip and having a second thickness smaller than the first thickness, and an annular inner section connected to the flexible connecting section, the outer lip having a bottom surface disposed in the annular recess and a top surface, and the protrusion being pressed into the top surface so that the outer lip seals between the upper housing portion and the lower housing portion.

Provided is a hose including a first connector assembly including a regulator assembly, a second connector assembly, and a hose assembly coupled to the first and second connector assemblies. The hose assembly includes an inner hose member having first and second ends, an outer hose member having first and second ends, a first hose connector assembly coupled to the first ends of the inner hose member and outer hose member and the first connector assembly, and a second hose connector assembly coupled to the second ends of the inner hose member and outer hose member and the second connector assembly.

Example embodiments relate to a gas-pressure regulator having an inlet, an outlet, a housing, a diaphragm, a control element, a control chamber and a discharge chamber. The inlet and the outlet each open onto the control chamber, wherein the diaphragm partially delimits the control chamber. The diaphragm and the control element are movable relative to each other, wherein a passage between the control chamber and the discharge chamber is open in a relative discharge arrangement of the diaphragm and the control element. An adjustable biasing element impedes a relative movement between the diaphragm and the control element.

Provided is a hose including a first connector assembly including a regulator assembly, a second connector assembly, and a hose assembly coupled to the first and second connector assemblies. The hose assembly includes an inner hose member having first and second ends, an outer hose member having first and second ends, a first hose connector assembly coupled to the first ends of the inner hose member and outer hose member and the first connector assembly, and a second hose connector assembly coupled to the second ends of the inner hose member and outer hose member and the second connector assembly.

A pressure reducer assembly (100) for adjustably reducing a pressure of a fluid includes a pressure reducer body (110) defining at least a part of a pressure reducer chamber (120) along a central axis (X-X). The pressure reducer chamber (120) includes an inlet section (122) and an outlet section (124) fluidly coupled with the inlet section (122). A biasing means piston rod (132) having a center (Y) along the central axis (X-X) connects the inlet section (122) with the outlet section (124) and is axially moveable with respect to the pressure reducer body (110). The pressure reducer assembly (100) is characterized in that the piston rod (132) includes an interaction protrusion (133). The pressure reducer assembly (100) further includes an adjusting device (140) comprising an actuating part (141, 143) and an adjusting part (142). The adjusting part (142) is configured to functionally interact with the interaction protrusion (133) such that a maximum axial movement of the piston rod (132) is adjustable by actuating the actuating part (141), particularly by manually actuating the actuating part (141).
