The function of a butterfly valve is to control the flow of a medium through a pipe. In the cross-section of the flow, a rotatable disc ensures the required flow. If the disc of the butterfly valve is parallel to the flow, it is fully open.
The butterfly valves from END-Armaturen are versatile valves that are flow-efficient in design and can be easily automated. In addition to long service lives and switching cycles, they impress with their robustness and adaptability.
Manual operation of the butterfly valves is possible with a worm gear or a hand lever. The hand lever can be adjusted in 10 locking positions and use a grid disc to show which position the valve disc is in.
Pneumatically operated butterfly valves are used very frequently because they are much safer compared to electrical variants when used in a plant area that is at risk of explosion. Pneumatic actuation can be implemented using two types of actuators.
Both pneumatic and electrically actuated butterfly valves are particularly suitable for applications where the valves are to be operated very frequently or remotely. Pneumatically actuated butterfly valves should be selected in plant areas that are at risk of explosion, as they are then safer
Butterfly valves can be operated manually or automatically. The automation here is associated with little effort. In order to design a suitable actuator for automation, the following questions must be answered:
Depending on the type of medium and the butterfly valve, the built-in sleeve may wear out. Sleeves are particularly stressed by aggressive media, for example due to mechanical or chemical effects. You will find a large selection of sleeves as spare parts for different series and sizes in our shop. Some sleeves have additional reinforcement rings for even greater resistance.
Butterfly valves are used for a wide variety of applications, machines and media. For example, flows of liquids and gases can be effectively regulated.
Butterfly valves can be used for a large number of media – regardless of whether they are systems, machines or tank and silo vehicles, for example. A few examples in the overview:
The wafer-type butterfly valves Art. WA are clamped between two flanges according to EN 1092-1. Without using additional flange seals.
The LUG-type butterfly valve Art. WM are also screwed directly onto a flange. This results in smooth transitions within the pipeline without dead spaces or turbulence.
The butterfly valves are immediately available from stock in the nominal sizes DN50 up to DN300. The versions are differentiated by the type of installation in the pipe system.
There is a wide variety of butterfly valves. The prices are affected by the following factors:
In our online shop we have an extensive range with over 900 different butterfly valves. Find out about current prices, approvals, additional data sheets with technical information and instructions.
