The requirements of a diaphragm valve i.e. filter valve are:
- Steep rising edge and large air flow rate for efficient compressed air shock and therefore optimal cleaning of the filter element
- Fast closing for low compressed air consumption
- High life cycles for nearly maintenance-free operation.
RECO filter valves meet these requirements with power-reflex diaphragm, a polymer diaphragm with "Crisp-frog effect". The housing is made of aluminum. The diaphragm valves are both with integrated pilot solenoid valve (24V DC or 230V AC) as well as externally controlled (external pilot valve) available. Commonly used port size G 1.
