A cap for cooperating with a flow control element of a valve for a self-priming electric pump, the valve being designed to open and close a recirculation duct for the passage of the recirculating fluid from the impeller assembly to an intake duct, the cap having a tubular body and, coaxially inside the latter, a mushroom-shaped element, which divides, with its head, the cap into a first portion and a second portion to be applied at an opening of the recirculation duct outward, respectively in the overhead and underhead installation of the self-priming electric pump, the axial space occupation of the head and of the stem of the mushroom-shaped element that is extended from the head toward the second portion defining two alternative axial positions of interaction with the flow control element of the valve in the overhead and underhead installation.
摘要:
A double valve has two coils which can be piloted separately from each other and which each have a core. The coils are arranged in a common valve housing, and a flange housing is mounted to the valve housing. Two valve seats are arranged in the flange housing, and a diaphragm is associated with the two valve seats, with each coil being associated with one valve seat.

摘要:
A switchbox for monitoring the position of a manual quarter-turn valve has a housing mountable to the valve to be monitored/controlled. A handle-driven shaft extends through the housing, with one end of the shaft couplable to the valve stem such that movement of the shaft moves the valve stem. One or more shaft position sensor switches interact with a cam on the shaft to signal shaft position and/or provide control signals. A plate coupled to the shaft articulates within a recess on the surface of the switchbox to limit motion of the valve to an operable range, such as between full ON and full OFF. The switchbox has a pair of lock tabs with lock apertures. A lock aperture in the plate is alignable with the lock tab apertures to receive a pin or padlock for locking the valve in a selected position. A potentiometer can be utilized in place of a switch as a shaft position sensor. The switchbox may be used with an original or new handle and may feature detents to allow a range of valve settings.
摘要:
A valve for installation in a valve bore of a housing or valve block includes a valve bushing for insertion into the valve bore, a guided valve piston that can be moved axially in the valve bushing, an activation section of said piston projecting above the valve bushing axially, and a valve cover that is configured to be arranged over the valve bore and that forms, together with the activation section of the valve piston, at least one activation pressure chamber.

A valve for a refrigeration system includes a valve body having an inlet port, an outlet port, and walls forming a main cavity. The valve also includes a cartridge that resides within the main cavity and having a piston configured to travel in a first direction to permit fluid flow from the inlet port to the outlet port and in a second direction to impede fluid flow from the inlet port to the outlet port and a port plate configured to removably couple to the valve body to substantially close an end of the main cavity substantially enclosing the cartridge within the main cavity, the port plate including a plurality of ports, each port configured to accept at least one of various valve control elements configured to control the piston to permit or impede the fluid flow from the inlet port to the outlet port.
