An axial piston pump may comprise a valve plate assembly including a plurality of valve plates rotatably disposed adjacent to each other and configured to control the flow of fluid between a piston chamber and inlet and outlet port passages. The piston pump may also comprise a swashplate arrangement that is capable of being angled in two different directions to be used in combination with the valve plate assembly. A fixed displacement axial piston pump may also comprise the valve plate assembly disclosed herein in which pressure transitions are facilitated in the same fashion, but without the variable of changing swashplate angles which control pump flow.

Disclosed is a flow control valve 100. The flow control valve 100 comprises a cylindrical body 20, a piston 40, at least one fluid seal 60, a handle 60 and a nut 90. The flow control valve 100 is connected between an inlet and an outlet of a pipe to control flow of liquid/gases passing there through even at high temperature and pressure. The flow control valve 100 provides good force to the liquid/gas passing there through and provides an equal distribution of the flow at the outlet without resulting in pressure drop.

A disc for a multiple orifice valve includes a disc body and a disc orifice extending through the disc body. A disc surface of the disc body includes a recessed portion and a raised portion that at least partially circumferentially surrounds the recessed portion. The recessed portion is configured not to contact an opposed disc when the disc is assembled within a housing of the multiple orifice valve, and the raised portion is configured to contact the opposed disc when the disc is assembled within the housing of the multiple orifice valve.

A fluid flow control system having a fluid inlet configured to be operatively coupled to a fluid source, a fluid outlet in fluid communication with the fluid inlet such that fluid may exit the system therethrough, a proximity sensor for detecting the position of an object within a region adjacent the sensor, and a flow control device configured to regulate fluid flow between the inlet and outlet in response to object detection by the sensor, wherein the flow control device varies the fluid flow proportional to the detected distance of an object from the sensor. A water flow control system for use in a shower environment is also provided, as well as a shower control system, methods for controlling water flow based on sensing of the presence and location of an object, and methods for reducing water consumption.

The invention relates to a valve for modulating flow and pressure used in tubing for the transportation of liquids, which modulates the flow and pressure of the fluid, preventing the generation of air bubbles and the passage of these through the tubing, thereby preventing them being registered as consumed cubic metres. The valve comprises: two adapters with a female thread on the outer parts of the valve, same containing the internal parts of the valve; a bar having a variable number of perforations or holes, same containing a mobile disk; a mobile disk having a variable number of perforation or holes; a stainless steel screw joined to the mobile disk; and a PVC pipe containing the bar, the mobile disk and the stainless steel screw.

A throttling valve that allows an operator to remove and replace the flow trim of the throttling valve without disassembling and/or removing the throttling valve from a flow line, and without removing an actuator, which eliminates the need to recalibrate said actuator. The throttling valve also allows drops in fluid pressure to be staged upstream and/or downstream of a main multi-port-disc trim within the same valve body to help prevent cavitation and freezing of fluids contained within the valve. The throttling valve also allows direct connection of actuators to a valve body.
