9, valve stem, especially the threaded portion, often should wipe, lubricant has been dirty dust would be replaced by new, because of the hard stuff is contained in the dust, easy to wear and tear of thread and the surface of the valve stem, affect the service life of pneumatic single-seat regulating valve < br / >
