Dongguan spp industry Co.,Limited showcased some of our hydraulic and pneumatic components such as: hydraulic spool and sleeve, valve seat, valve needle, valve stem, valve shaft, valve body, etc. through the exhibition.

Precision hydraulic valve components generally require grinding processes. spp-industry has a wide range of grinding technologies combined with advanced grinding equipment. Internal and external cylindrical grinding machining, honing, profiling grinding, etc.

Precision spool and sleeve often require a high precision fit effect, and SPP has about 20 years of experience in this area. Whether it is a precision fit (no oil or water leakage) or a sliding fit (fit clearance of about 0.01), we can do it all.
