Butterfly valve housing for a butterfly valve having a closing element mounted rotatably in the housing, wherein receiving openings are arranged in the housing between the two flange connection discs and between the reinforcement structure, wherein the receiving openings are directed from the outer circumference in the direction of the vertical centre axis, into which the inserts can be inserted into the housing, wherein the inserts are arranged form-fittingly in the receiving openings.

Butterfly valve housing

Butterfly valve for shutting off or regulating a medium, which flows through a pipeline, containing a housing, wherein the housing is configured in one piece and is preferably composed of plastic, a disc and a shaft, wherein the disc can be pivoted along the shaft between an open position and a closed position, wherein the disc comprises a core composed of plastic and a shell composed of plastic, wherein the plastic of the core and the plastic of the shell are different.

Butterfly valve

Hand lever, preferably produced from plastics material, for operating a valve, preferably a butterfly valve or a ball valve, including a lever and a locking plate, wherein the lever comprises a locking element and a lever upper part, wherein a fastening element for fastening on a valve and for connection to the locking plate is arranged on the lever upper part and the locking plate comprises a receiving opening for receiving the fastening element, characterized in that the receiving opening is realized in an oval manner and the fastening element comprises a round cross-sectional area or the fastening element comprises an oval cross-sectional area and the receiving opening is realized in a round manner, wherein the oval and round contour of the receiving opening preferably comprises at least one recess or slot.

Hand lever

Valve for fluid and gaseous media, more particularly for regulating the pressure in pipelines, containing a housing of at least one upper and lower part, a pressure adjustment unit, wherein the pressure adjustment unit comprises a spindle, a spring plate, a spring holder and at least one spring, a cartridge, wherein the cartridge forms a function unit by means of which the function of the valve is defined, wherein the cartridge preferably contains an interior housing, a fastening means, a poppet and a diaphragm, wherein the diaphragm serves for dividing the housing into a medium-free and a medium-flowing area, wherein the cartridge is pre-fitted as a function unit and is disposed replaceably as a complete unit in the housing.

Valve having an exchangeable cartridge

A valve includes a leakage indicator and a valve housing. The valve housing includes a valve housing upper part, a valve housing lower part, and a diaphragm. The diaphragm divides the valve housing into a fluid-flow area and a fluid-free area. The leakage indicator is an absorbent element that projects into the fluid-free area.
