Certain embodiments provide a cover mounted on top of a manifold, the cover comprising an exhaust opening and an inner surface forming a space between the inner surface of the cover and an outer surface of the manifold, wherein the space is configured to receive pressurized gas at an inlet positioned on a first side of a valve. The valve is coupled to the outer surface of the manifold and positioned within the space. The exhaust opening is positioned on a second side of the valve opposite the first side of the valve such that pressurized gas circulates from the inlet around the valve and exits through the exhaust opening.

This heating assembly comprises a thermally conductive tube (42), to be immersed in a thermally expandable material of a thermostatic element of a valve, an electric heating resistor disposed inside the tube and from which there extend electrically conductive wires (62), and a unitary housing (1) made from plastic, through which the fluid to be regulated flows via the valve, and which is secured by over-molding of a longitudinal end portion (44) of the tube. In order to make the molding of the over-molded housing simple and inexpensive to carry out, while being easy to adapt to various geometric forms of the heating assembly, the invention proposes that, before the housing is molded, a reinforcement (7) for supporting the wires outside the tube, which is separate from the housing, and to which the housing is secured by over-molding, can be securely mounted on the end portion of the tube and supports the wires outside the tube, said wires being externally mounted on the reinforcement, and, when the housing is being molded, keeps the wires in place while the plastic material of the housing coats these wires, the reinforcement and the end portion of the tube.

A plumbing fitting includes a housing and a missing valve. The housing includes a first aperture, a second aperture, a third aperture, and a mixing chamber in fluid communication with the first aperture, the second aperture, and the third aperture. The mixing valve is disposed within the housing. The mixing valve includes a first flow control valve that is configured to control a first flow of fluid from the first aperture to the mixing chamber.

An in-line shutoff valve includes a valve body with an inlet chamber, an outlet chamber, and a poppet seat disposed between the inlet and outlet chambers. A poppet is movably disposed within the valve body and has an open and closed position. The poppet seats against the poppet seat in the closed position, fluidly separating the inlet chamber from the outlet chamber. The poppet is unseated from the poppet seat in the open position, fluidly coupling the inlet and outlet chambers. A manifold with a servo port and a vent port is disposed within the valve body between the inlet and outlet chambers, the vent port being in fluid communication with the servo port to cool valve internal structures when the poppet is in the closed position.

A temperature-controlled pressure regulator assembly includes a regulator having a regulator body, a valve seat, an inlet, an outlet, and defines a flow passage connecting the inlet and the outlet. A control element controls the device, a portion of the flow passage extends through a heat chamber, and a heater is positioned to heat the chamber thereby conveying heat to a fluid in the flow passage. A controller is electrically coupled to the heater and is coupled to a power source. A thermal cut-off fuse is coupled to a control circuit, with the thermal cut-off fuse arranged to electrically decouple the heater from the control circuit in response to a temperature exceeding a threshold, thereby deactivating the heater. The thermal cut-off fuse is disposed in a circular fuse holder and positioned adjacent the heater and adjacent a longitudinal center of the heat chamber.

A block valve and a block valve for a raw material container having a structure in which a retaining part of a liquid material or cleaning fluid is not present inside. In a block valve (10), one side of a main flow path (18) communicating with a supply route (14) of a block body (11) and a first minimal port part (21) of a first diaphragm valve (12) disposed in a tilted state with respect to the block body are connected, another side of the main flow path and a second minimal port part (22) of a second diaphragm valve (13) are connected, a port opening (25) of the second diaphragm valve is communicated by a supply port part (15), and a joint port part (23) of the first diaphragm valve and a connection line (16) in a vertical direction are connected by a communication path (19).

A valve control assembly includes a valve body having an inlet adapted to be coupled to a source of process fluid having a first temperature, an outlet, and a fluid flow path extending between the inlet and the outlet, and a bonnet coupled to the valve body. An inlet port, an outlet port, an annular plenum, an inlet passage, and an outlet passage are integrally formed in the valve body or the bonnet. The inlet port is adapted to be coupled to source of media and the annular plenum is disposed between the inlet port and the outlet port, immediately adjacent a portion of the fluid flow path. The inlet passage directs the media from the inlet port to the annular plenum, which changes a temperature of the process fluid flowing through the fluid flow path from the first temperature to a second temperature different from the first temperature.

A multi-way valve includes an outer casing provided with an internal cavity, at least one input to the cavity, at least one output from the cavity, the at least one input having sealing means, and an actuator adapted to cause the opening of the sealing means of the inputs. A cross-section of the actuator is smaller than a cross-section of the inner cavity.
