The flow switch of the FF series comes in different housing sizes in industrial high-pressure cleaning technology. For example, in industrial washing machines, car, truck or self-service car washes as well as in refrigeration or hydraulic applications.

Robust and flexible

The simple mechanical operating principle of the piston valve seat design means that it is practically maintenance-free in all applications. The volume flow raises a piston (fitted with a magnet) out from a valve seat against a spring force. The stroke causes a magnetic field change that actuates a hermetically isolated Reed switch and generates an electrical signal with the spring-supported stabilization of the piston and the short installation length of the housing use is possible in all installation positions. The range consists of housing sizes for nominal pipe widths from DN 8 to DN 50 and freely selectable switching values from 0.4 l/m.

Fast, precisely und long-lasting

You benefit from a quick response <100 ms and a high switching value repeatability > 1,000,000 switching operations. With an average switching frequency of 30 switching operations per hour, the service life is min. 30,000 operating hours. The ideal flow monitor with low pressure loss to ensure reliable operation of your application.

Piston valve seat design for low investment costs

The flow switch FF is designed as a device family with a piston valve seat design. As if made to be used in large quantities with outstanding economy. The devices are independent of location and can be installed as required.
