The rotary valve adopts sapphire spool, which can be applied to all kinds of corrosive liquids. The valve head is processed by PCTFE (polytrifluoroethylene), which is maintenance-free.
Spool rotor rotation depends on the planetary reducer motor as the power device.
Advanced zirconia ceramic processing technology, strict inspection procedures, unique sealing scheme, to ensure that the service life of the valve can reach more than 1 million times, without maintenance and care.
Contact with liquid medium parts of the material of good chemical resistance. Various materials can be selected to ensure the compatibility of chemical media.
