Abstract: Welded check valves include a poppet assembly, a spring, and a disc that contacts the spring. The disc may be held at a position away from a weld when forming the welded check valve. Embodiments may include retention features configured to allow one or more of the poppet assembly and disc to pass the retention features in an assembly orientation, and to retain those elements when they are in an operational orientation. Methods include inserting the poppet assembly, contacting the poppet assembly with a spring, inserting a disc, retaining the disc away from a weld side, and welding the check valve together. The poppet assembly and/or disc may pass one or more retaining features when inserted, and be retained by the retaining features when the check valve is operated. The weld may be a thermal weld.

Abstract: The invention relates to a conveyor device for a vacuum distillation plant for substance mixtures that polymerize and/or decompose readily, in particular acrolein, in which plant an intermediate product formed in a preliminary stage is delivered by means of a pump into a vacuum distillation column (37). The invention is characterized in that the pump is a hermetically sealed centrifugal pump (31) having a magnetic coupling, and in that a pressure holding control valve (34), which is configured to adjust the throughput of the centrifugal pump (31) to a predetermined value, is provided between the centrifugal pump (31) and the vacuum distillation column (37).

Abstract: Poppet valve for a piston compressor, having a valve body with a plurality of inlet ducts, wherein each inlet duct has an inlet section and an outlet section. The outlet section opens into a valve seat, wherein each inlet duct is assigned a closing element and a spring. The closing element can be moved in an axial direction (A) in such a way that the valve seat can be closed by way of the closing element. The spring has a first spring end section and a second spring end section, wherein the spring is arranged in the inlet duct and bears with the first spring end section against and is held on the inlet section of the inlet duct. The second spring end section is connected to the closing element, to bring about a pre-stressing force on the closing element, which pre-stressing force is oriented towards the valve seat.

Abstract: A pressure relief valve includes a valve seat at the outlet, a valve body, and an air dashpot damper. In some embodiments, the valve body is configured to engage the valve seat and move along a central axis relative to the valve seat in response to a pressure at the outlet to regulate a flow of combustible gas through the outlet. In some embodiments, the air dashpot damper includes a tubular member having a closed distal end and an open proximal end, and a piston member received within the tubular member. In some embodiments, the tubular member or the piston member is attached to the valve body, and the piston moves relative to the tubular member along an axis of the tubular member in response to movement of the valve body relative to the valve seat. In some embodiments, the pressure relief valve includes a plurality of the air dashpot dampers.

Abstract: A coupling apparatus for a floor drain which includes a hollow body having an exterior surface and an interior surface, with the interior surface defining a flow chamber. A primary inlet extends through the exterior surface of the body into the flow chamber; the primary inlet being of a first size to accommodate a drainage line from a hot water tank. At least one secondary inlet extends through the exterior surface of the body into the flow chamber. Each secondary inlet is of a second size, smaller than the primary inlet, in order to accommodate a smaller drainage line. A single outlet through the exterior surface of the body is provided for draining the flow chamber.

Abstract: A charge air cooler comprises an outlet tank having a drain mechanism integrated in a wall thereof. The drain mechanism comprises a first valve head disposed to a first side of the wall, a first spring member disposed between the first valve head and the wall, a second valve head disposed to a second side of the wall, a second spring member disposed between the second valve head and the wall, and a valve stem coupled to each of the first valve head and the second valve head. The valve stem is reciprocatingly disposed within an aperture formed in the wall. The drain mechanism is configured to be in a closed position when an internal pressure within the outlet tank is at least one of greater than a first pressure value and lower than a second pressure value.

Abstract: A check valve is provided which may be installed horizontally or in other non-vertical orientations, and used with variable frequency drives and other applications without the valve becoming misaligned. In one aspect, the valve includes a housing with an inner surface and a passage. A flange within the housing divides the housing into upstream and downstream portions, and extends around the inner surface, defining a valve seat and a valve aperture. A poppet is positioned in the downstream portion. The poppet includes a valve head and a plurality of guide legs extending from the valve head and into the downstream portion, and not through the valve aperture. The valve head is resiliently biased in the closed position against the valve seat to inhibit fluid flow in a first direction. A guide disposed within the housing receives the plurality of guide legs of the poppet valve as the poppet valve moves between an open position and a closed position.
