The transmission thread on the stem of the rising stem gate valve is exposed outside the valve body, which can intuitively determine the opening and closing of the gate and its position; The rising stem gate valve is driven up and down by the thread transmission between the valve stem and the steering wheel, which drives the gate to rise and fall. When the rising stem gate valve is fully opened, the height is relatively large, requiring a large installation space

The sealing surface of the gate is processed once, followed by a copper welding process to weld a layer of copper onto the sealing contact surface, and then processed again to improve the hard sealing effect based on the softness of the copper,

Bright stem hard seal gate valve is a universal valve type widely used in fluid control in industries such as petroleum, chemical, and metallurgy. Hard sealed gate valves have the characteristics of low resistance, good sealing performance, and strong cutting ability, and are one of the indispensable infrastructure in the industry.
