Product Information

The alloy steel gate valve has the characteristics of good product sealing performance, low fluid resistance, labor saving for opening and closing, small erosion of the sealing surface by the medium when the valve plate is fully opened, double flow directions, stainless steel and hard alloy for the sealing surface, and long service life. The stem of the stainless steel gate valve adopts an integral forging structure. The smaller diameter of the stem is in accordance with the standard. The stem and the gate are connected by a form structure. The strength of the connection is greater than the strength of the trapezoidal thread of the stem. The strength test complies with API591.
