Rising Stem Gate Valve

Rising stem gate valve is a common type of valves, mainly composed of valve body, valve cover, valve plate, valve stem. The characteristic of a rising stem gate valve is that the valve stem is exposed and can be directly operated by a handwheel or other driving device to drive the valve plate to achieve the function of opening and closing.Bright stem gate valves are usually equipped with trapezoidal threads on the lifting rod. Through the valve top nut and valve body guide groove, the rotational motion is converted into linear motion, thereby achieving the opening and closing of the valve and ensuring the complete smoothness of the fluid channel.

• Characteristics of rising stem gate valve

The main features of a rising stem gate valve include:
1. Compact structure: The structure design of the rising stem gate valve is reasonable, the valve rigidity is good, the channel is smooth, and the fluid resistance is reduced.
2. Reliable sealing: Flexible graphite packing and other sealing materials are used to ensure good sealing performance.
3. Easy to operate: The drive mode of the rising stem gate valve is diverse, including manual, electric, pneumatic and other forms, to meet different operational needs.
4. Material diversity: Valve body materials can be selected from cast iron, ductile iron, stainless steel, etc. to adapt to different working environments and media.
