RUNDONG Company can produce both upper and lower types of the oil machine parts to suit the general type pumps from BAOSHI and LANSHI factories. The upper valve guide is made from superior quality alloy steel by CNC machining. The lower valve guide is finely made from ductile cast iron. Both types have gone through heat treatment and special surface treatment for increased mechanical strength and corrosion resistance. Some models of the oil drilling equipment part are designed with additional guide sleeve. Split type metric and imperial general design helps customers reduce the operating cost.
