OEM Customized Piston Piston Rings - CONCENTRIC VALVE – DONGYI

FOR LUBRICATED AND NON-LUBRICATED COMPRESSORS

Smallest possible clearance volume, therefore maximum delivery volume

Low flow resistance

Compact, space-saving design

Concentric valves are a space-saving alternative to conventional inlet/outlet valves. They are suitable for all types of compressors in the lower power range.

In concentric valves, the suction and discharge parts are integrated in a common valve body. This allows a very compact design of the compressor. To achieve an ideal valve/cylinder head construction, the valves are individually tailored to the customer’s requirements.
