A valve member cooling arrangement for a valve having at least one housing with sets of working fluid inlet/outlet ports and coolant supply/return ports. A valve member movably disposed within a valve chamber has a valve head configured to control flow between the working fluid ports. The valve member has valve member inlet/outlet openings and defines an internal valve member cooling passage uniting the valve openings. At least one coolant sleeve is disposed about the valve member. The coolant sleeve(s) have inflow and outflow ports separated inflow from outflow by at least one seal. During static and dynamic positioning of the valve member, the valve member inlet(s) are in communication with inflow port(s) of the coolant sleeve, and the valve member outlet(s) are in communication with outflow port(s) of the coolant sleeve(s).

In a process valve P comprising a housing, which defines first and second seats on both sides of an intermediate chamber and which is connected to product lines and comprises a closing element with a metallic shaft and first and second valve disks having surfaces that face the product lines the surface of at least one valve disk is thermally decoupled from the valve disk to a very large extent. The process valve P with the thermal decoupling unit is installed in a node of a food treatment and/or filling plant.

Single-piece valve closure members (e.g., discs, plugs, balls, etc.) including integral flow paths formed via additive manufacturing processes are disclosed. In some examples, an apparatus includes a single-piece valve closure member. In some examples of the apparatus, the single-piece valve closure member includes an integral flow path to direct a flow of fluid within the valve closure member. In some examples, a method includes forming, via an additive manufacturing process, a single-piece valve closure member. In some examples of the method, the single-piece valve closure member includes an integral flow path to direct a flow of fluid within the valve closure member.

An internally cooled inlet or outlet valve for internal combustion engines, has a valve disc, a valve stem and a cavity inside the valve stem and the valve disc. A coolant is arranged in the cavity, wherein the cavity is provided with at least one guide vane for the coolant.

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.

Single-piece valve closure members (e.g., discs, plugs, balls, etc.) including integral flow paths formed via additive manufacturing processes are disclosed. In some examples, an apparatus includes a single-piece valve closure member. In some examples of the apparatus, the single-piece valve closure member includes an integral flow path to direct a flow of fluid within the valve closure member. In some examples, a method includes forming, via an additive manufacturing process, a single-piece valve closure member. In some examples of the method, the single-piece valve closure member includes an integral flow path to direct a flow of fluid within the valve closure member.

A drop-in valve assembly for a lube flow control valve for an OE valve body. The OE valve body has a bore that communicates with a solenoid inlet port, first and second cooler inlet ports, and a first sump port. A sleeve is configured to be positioned in the bore. The sleeve has openings configured for fluidly communicating with the solenoid inlet port, the first and second cooler inlet ports, and the first sump port therethrough. A valve member is configured to be positioned in the sleeve in the bore and to axially move therein between first and second positions. Moving the valve member from the first position to the second position at least partially reduces fluid communication from the first cooler inlet port to the first sump port and at least partially increases fluid communication from between the first cooler inlet port and the second cooler inlet port.

A method and an apparatus for supplying inert gas into a poppet valve intermediate are provided that are capable of properly filling the inert gas without waste into the poppet valve intermediate of any size. After a negative pressure is achieved by suction in an internal space (Win) of a poppet valve intermediate (W) as compared to an ambient pressure (Pa) of the poppet valve intermediate (W), the inert gas is supplied into the internal space (Win) until a pressure (F) of the internal space (Win) reaches the ambient pressure (Ps) of the poppet valve intermediate (W).

A hollow poppet valve (10) is provided with an additional flange shape cavity (S1a), in addition to an ordinary valve head cavity (S1) formed in the valve head (14) of the valve (10) in communication with a valve stem cavity (S2) formed in a valve stem (12). A coolant (19) is loaded in the cavities to facilitate dissipation of heat out of the valve. This flange shape cavity (S1a) extends radially outwardly round a bottom portion of the valve head cavity (S1), extending close to a valve seat, thereby significantly facilitating heat transfer between the coolant (19) and the valve seat of the valve, yet, since the flange shape cavity (S1a) does not influences the thickness of other regions of the valve, it does not degrade durability of the valve.

A heat exchanging valve arrangement includes, a manifold defining a chamber, a first passageway, a second passageway, a third passageway, and a fourth passageway, and a member movable relative to the manifold configured to define fluidic communication between the first passageway and the second passageway when in a first position and between the first passageway and the third passageway when in a second position, fluid is flowable into the chamber through the fourth passageway such that fluid is exposed to surfaces of the member regardless of whether the member is in the first position or the second position.
