Abstract: According to one embodiment of the invention, a control valve for regulating temperature comprises a conduit, a fluid limiter, a restoring actuator, an opening actuator, and a restoring actuator chamber. The conduit has an inlet, an outlet, and an opening between the inlet and the outlet. The inlet is operable to receive fluid into the conduit and the outlet is operable to dispense of fluid out of the conduit. The fluid limiter is operable to at least partially cover the opening and thereby resist flow of fluid through the opening. The restoring actuator is operable to provide a force that moves the fluid limiter toward the opening to resist flow of fluid through the opening. The opening actuator is operable to provide a second force that moves the fluid limiter away from the opening to allow the flow of fluid through the opening. The opening actuator is activated based on a temperature of fluid in the conduit. The restoring actuator chamber is disposed around the restoring actuator and has a passage in communication with fluid upstream of the opening.

Abstract: A constant flow rate control valve (10) is provided including a cup member (12) disposed in a flow passage through the valve (10). The cup member has an orifice (18) located in an end wall (14) of the cup member (12) and a plurality of side ports (22) in a side wall (16) of the cup member (12). The cup member (12) is moveable axially within the valve (10), with such movement being opposed by a resilient spring member (30) downstream of the cup member (12). The valve (10) includes a fixed retainer ring (26) in a valve body (24) surrounding the side wall (16) of the cup member (12) which blocks or exposes areas of the side ports (22) in response to movement of the cup member (12). Start up slots (34) in a side wall (36) of the valve body (24) are also blocked or exposed in response to movement of the cup member (12). Fluid pressure acting on the end wall (14) of the cup member (12) urges the cup member (12) against the spring (30), so that the retainer ring (26) exposes only that side port (22) area appropriate to the pressure being exerted and the cup member (12) exposes only that start up slot (34) area appropriate to the pressure being exerted.

Abstract: According to one embodiment of the invention, a system for regulating a temperature of a fluid through a conduit comprises a conduit, a moveable obstruction, an actuator, and a pressure generator. The conduit has an inlet, an outlet, and an opening between the inlet and the outlet. The inlet is operable to receive fluid into the conduit and the outlet is operable to dispense of fluid out of the conduit. The moveable obstruction is operable to at least partially cover the opening and thereby resist flow of fluid through the opening. The actuator has a chamber with a heat sensitive substance. The heat sensitive substance is operable to change a characteristic upon receipt of thermal energy from fluid traveling through the conduit. The actuator is additionally operable to move the obstruction upon the change in characteristic of the heat sensitive substance. The pressure generator is operable to apply pressure to the chamber to change a property of the heat sensitive substance. The change in property of the heat sensitive substance changes the movement of the obstruction by the actuator.

Abstract: According to one embodiment of the invention, a method for regulating temperature in a system comprises receiving, at a building management system, information concerning a degree of opening of a plurality of control valves. Each of the plurality of control valves is associated with at least one terminal that is in communication with a supply header line of a system, and is operable to open or close according to its own logic based on the demand of the associated terminal or terminals. A determination is made, based on the degree of opening of the plurality of control valves, as to whether changes need to be made to the operating parameters of production equipment of the system. The changes to the production equipment operation of the system are operable to change at least one parameter of a fluid being supplied to the supply header line of the system. An initiation of changes is made if it is determined that the change needs to be made. The changes in the production equipment yield a difference in the at least one parameter of the fluid.

Abstract: According to one aspect of the invention, a fluid regulating control valve includes a housing having an upstream region and a downstream region and having a control orifice formed therein adjacent the downstream region and a piston slidably disposed within the housing. The piston has a fluid passage defining an intermediate region disposed between the upstream region and the downstream region and an edge adjacent the downstream region. The valve also includes an elastic member disposed within the housing for opposing translation of the piston within the housing and a throttling element adjacent the upstream region. The throttling element has a throttling surface adjacent the edge of the piston, in which the throttling surface and the edge define a throttling orifice therebetween. The valve further includes an equalization aperture formed in the housing to allow a fluid in the downstream region to enter an equalization chamber defined by a region between an inside surface of the housing and an outside surface of the piston.
