This design of this product is different from market-sale products because during structure renovation, generally, need to replace parts, i.e. disassembly 20 pieces of screws; but for this product, replacing of one side diaphragm can be achieved by only replacing 7 pieces of screws, easy to be repaired and maintained. Double-layer diaphragm, outer layer is made of special Teflon material that is characterized with solution-resistant, more durable than common Teflon, low initiation pressure (about 1.5kgf/cm2); RDP-12-R available (coating-depressurized valve attached), stable coating output, accompanying slight pulse. It could operate below 6bar (not idle operation), alligatoring-hide crack or break resistant, longer use period than other relative products of normal operation.
RDP12-R: coating-depressurized valve attached; slight pulse, suitable to coating conveyance and not influence to spraying.
