Pneumatic Air Feeder

The central hole of the main structure is by lapped finishing first and then electroplating so as to better ensure its roundness and straightness, which thus enables the core shaft to run smoothly. After processed, the main structure goes through anti-corrosive treatment, and then it is cleaned through ultrasonic wave before assembled so as to guarantee trouble-free when processing leftover materials. The exchangeable reversal valve is constructed large circular angle and its internal bore goes through mirror polishing treatment so as to greatly improve feeder’s loading speed and the life span of sealing ring. All the sealing parts are introduced from Japan.
