API600 Stainless Steel High Pressure Rising Stem Gate Valves

JOEPAI customized API600 Stainless Steel High Pressure Rising Stem Gate Valves move in a straight line with the valve stem is called a rising stem gate valve (also known as a rising stem gate valve). Usually, there are trapezoidal threads on the lifting rod, which convert rotational motion into linear motion through the matrix at the top of the valve and the control slot on the valve body, that is, converting working torque into working tension. Some valves have a valve stem matrix installed on the door panel, and the handwheel rotates to drive the valve stem to rotate, thereby lifting the door panel. This valve mode is called a rotary valve or a hidden valve.

Product Features

1. Double sealing pair, reliable sealing, smooth channel, and low flow resistance coefficient.
2. The sealing surfaces of the gate and valve seat are made of hard alloy welding, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant, and has a long service life.
3. Medium to large diameter valve stem thrust rolling bearings are installed, which are flexible in opening and closing and easy to open and close.
4. The valve stem has undergone quenching and surface nitriding treatment, exhibiting excellent corrosion resistance, bite resistance, and wear resistance.
5. It is relatively labor-saving when opening and closing, and the switching speed is relatively slow, making it less prone to water hammer phenomenon.
6. Large height dimensions require a large installation space
7. Valve materials can be reasonably selected according to actual working conditions or user requirements, and can be suitable for various pressure, temperature, and medium working conditions.
