The flange-butterfly valve is a valve used to control the flow of fluids in pipelines. With this kind of valve the flow will be changed by a rotatable disc in the flow-cross section.

Due to the double eccentric valve-disc (streamlined shape) the flange-butterfly valve is almost maintenance free and mainly used in water- and waste water treatment plants.

Technical Data

This two-part butterfly valve is often used for chemical plants to handle aggressive media. For this purpose is PTFE for the seat ring and for the disc coating particularly well suited.

There are two different flange designs:

Technical Data

High performance butterfly valves are suitable for sophisticated applications at most difficult conditions.

The disc is built-in in double eccentric and triple eccentric version into the housing. The straight incident flow protects against corrosion and abrasion equally. The spheric sealing surface at the disc enables nearly wear-free operating at highest tightness and minor torques. The shaft seal underneath the head flange is adjustable without dismantling the actuator. High performance butterfly valves are available as wafer or lug type.

Diaphragm valves are generally used to control a medium inside a pipeline. Especially for aggressive and/or viscous media (with solids) the use of a diaphragm valve is recommended.

Due to the design this valves are absolute tight and easy to maintain. Diaphragm valves are available with various linings, like PTFE, Halar, Viton, EPDM or NBR. The type of the flange connection (flange, screw socket, welding flange), as well as the construction type (straight bore, weir type) can be predefined by your requirements.

Technical Data

Highly recommended is the use of this valve for high temperature (up to 600°C), due to the fact that the valve disk and the metal valve seat make the use of conventional sealing materials unnecessary.

Technical Data

In bellow globe valves the shaft, that lifts/lowers the valve disk, is covered with a stainless steel bellow. This gives and additional sealing and furthermore high protection against undesired leakage to the valve.

Technical Data

Vent valves and air relief valves are mainly used in silo structures or in water pipes. It's task is the pressure compensation inside a pipe or a container.

By filling the silo the valve shall relief the pressure to prevent overpressure which could burst the silo. By emptying the silo the valve has to vent the depression in the closed system because the ambient atmosphere could compress the silo. According to the system's volume one- or two-piece version and various size ranges can be chosen.

Technical Data

Foot valves are generally used for withdrawal (pumps) of liquid media which could be polluted with undesired solids.

Basically it is a check valve with a preceding strainer. By using the check valve and the strain-filter the medium will be suctioned and cleaned. The check valve prevents the back-flow into the polluted medium.

Technical Data

The purpose of safety valves is to prevent a system and its components against excessive pressure increases.

To ensure this prevention, the valve has a spring-loaded valve, which opens at a predefined counter-pressure to release the overpressure into the ambit or a by-pass line. Due to that a potential damage of the pipe and/or other components is prevented. After reducing the unwelcome overpressure, the valve closes automatically.

Technical Data

The use of a needle valve is highly recommended for subtle dosing at small size ranges, high temperature (up to 305°C) and high pressure (>100bar).

This valves are absolutely suitable as shut-off device at measurement tasks for fill-level and flow rate.

Float valves control fill-levels of inflow and outlet. If the fill-level in a container lowers, the float will also lower and open the valve by a a lever; so the medium can flow in.

When the float reaches a defined level, the inflow closes again. Float-valves are available in various materials and with different types of opening.

For media with unfavorable viscosity and, as the case may be with solids, its recommend the use of a hose pinch-valve.

The medium flows through a flexible tube element. By the use of a hand wheel or a pneumatic cylinder, the tube will be hardly pressed together and the line will be closed safely. We provide various types of connection for this kind of valve; for example closed or opened versions with flanged or threaded ends. Generally this valve will be installed for up to 4 bar overpressure. On request we provide hose pinch-valves for a pressure range up to 40 bar.
