摘要： The pressure retaining valve has a housing (1) with an inlet channel (4) and an outlet channel (5) which can be connected thereto. A valve piston (8) with a valve spindle (11) is fitted to move in the housing. The valve piston (8) is loaded by a spring (7) towards the valve seat (3) and, in its closed position, shuts off the connection between the housing inlet (4) and outlet (5) channels. A diaphragm (9') separating the spring (7) and the valve piston (8) is mounted in the housing (1). Between the separating diaphragm (9') and the valve seat (3) there is a guide plate (10) movably guiding the valve spindle (8). It surrounds the valve spindle (8) to form a narrow annular gap (12) acting as a choke, thus preventing control oscillations. To make the valve proof against counter-pressure, the area of the valve seat (3) corresponds to the active area of the separating diaphragm (9').

摘要： A relief valve for low pressure operation includes a valve body (12) having an enlarged cylindrical bore (20) in alignment with an inlet port (16) and defining a valve chamber (22). An outlet port (18) opens laterally from the valve chamber (22). A seat insert (80) is received in the bore (20) and defines an axially facing raised seat (92) circumferentially about the inlet port (16) at a location closely adjacent the outlet port (18). A poppet valve member (50) with a truncated conical configuration and a maximum outer diameter only slightly less than the inner diameter of the enlarged bore (20) is mounted for engaging the seat (92) and blocking flow through the inlet (16). A biased stem (44) extends into the valve chamber (22) in axial alignment with the seat (92). The stem (44) has a cylindrical end portion which is recieved in a cylindrical opening (110) formed axially into the poppet valve member (50) on the end thereof opposite the seat insert (80). The cylindrical end portion and the cylindrical opening are sized to permit lateral shifting and alignment of the poppet valve member (50) relative to the seat (92) while preventing excessive and unwanted tilting of the poppet valve member (50) relative to the bore (20).

摘要： The invention relates to a backflow preventer (1) comprising a valve member (6) in the interior (5) of the insertable housing (2) thereof. Said valve member (6) sealingly rests against a valve seat (7) in the closed position thereof while being movable from the closed position thereof into the open position thereof counter to a restoring force. The interior (5) of the housing is provided with an interior section (A) which has an interior cross section that is larger than the outer circumference of the valve member in the movement zone of the valve member (6). The aim of the invention is to prevent undesired noise from developing as a result of the valve member (6) vibrating on the inner circumference of the housing also when the quantity of penetrating medium is low. Said aim is achieved by providing at least the movement zone of the backflow preventer (1), which is located near the valve seat (7), with an elastic valve member guide (9) that is effective between the valve member (6) and the interior housing wall surrounding the interior section (A) so as to guide the valve member (6) free from play.
