Abstract: A sealing ring provides a fluid seal between a first flange and a second flange. The sealing ring forms a tubular element and includes a tapering wall member defining an interior funnel-shaped through-going opening extending axially and tapering from a proximal end to a distal end. The tapering wall member is made from a resilient material proving an axial deflection of the tapering wall member when exposed to an axial force.

Abstract: A hydraulic valve includes a valve housing (4) with an inside that defines at least one first flow path (7), and with a valve insert (16) which is arranged in the inside of the valve housing (4). The valve insert (16) includes a movable valve element (14) situated in the first flow path (7). An infrared temperature sensor (46) is arranged on or in the valve housing (4) and is directed onto a surface of the valve insert (16) or a surface of a thermal conductor (48) connected to the valve insert. A hydraulic manifold may be provided with such a hydraulic valve.

Abstract: Some particular preferred embodiments relate to the field of pumping stations for sewage and wastewater with submersible pumps mounted in the bottom of the wells. To allow easy cleaning and maintenance of the pumps without getting in contact with the dirty water the solution is a system for easy lifting of the pump out of the well and lowering the pump again with an auto coupling.

Abstract: A hydraulic heating and/or cooling system hydraulic manifold is constructed in a modular manner with a main module (2). At least one load module (4) is connectable to the main module (2) and includes a hydraulic connection (22, 24) for a load circuit, and a closed-loop control device (26, 28) controlling flow through the load and for connection to an identically configured further load module (4). The at least one load module (4) includes a circuit board (44) which extends between a first (34) and a second axial end (36) of the load module (4) and which at its first (34) and second end (36) have electrical couplings (50, 52) which correspond to one another. The electrical coupling (52) at the second end (36) of the circuit board (44) can electrically conductively engage with an electrical coupling (50) at the first end (34) of the further identical load module (4).
