Product Description

The stainless steel gate valve has the characteristics of good sealing performance, low fluid resistance, low opening and closing effort, small erosion of the sealing surface by medium when the valve plate is fully opened, double flow direction, stainless steel and cemented carbide used in the sealing surface, long service life and so on. The stem of the valve adopts integral forging structure. The smaller diameter of the stem is in accordance with the standard. The connection between the stem and the gate plate is in shape. The strength of the connection is greater than that of the trapezoidal thread of the stem. The strength test of the connection between the stem and the gate plate conforms to API 591.
