FRANK GMBH products

Diaphragm valves allow a secure shut-off of difficult fluid media and a certain control to some extend. Since only the body and diaphragm get in contact with the media, diaphragm valves are extremely suitable for aggressive fluids. Thanks to the design of FRANK diaphragm valves they can also be used for abrasive and solid-containing fluids. In case of hot, moist chlorine (for chlorine electrolysis for example), we recommend our unique EL-PVDF diaphragm valves. A travel stop mechanism is a standard feature of our diaphragm valves.

Butterfly valves are characterized by their short overall length. FRANK plastic butterfly valves are robust valves for extremely sophisticated applications. They are corrosion resistant and easy to handle thanks to the top flange dimensions being in line with DIN EN ISO 5211 for automation and thanks to their relatively low weight. Our butterfly valves are available with a lever which can be locked in 5° increments or with a corrosion proof plastic gear unit.

Gate valves are used to regulate and close off flow volumes. They are often used in water industry, especially water treatment.

The free circular passage in the "OPEN" position ensures little pressure loss. The ball enables the flow to be shut off quickly. Our ball valves stand out because they can be connected in so many different ways. The top flange dimensions in line with DIN EN ISO 5211 allow straightforward automation. We recommend the FRANK ball valve with relief well for gas emitting media.
