How to Distinguish between Rising Stem Gate Valves and Non-Rising Stem Gate Valves?
Dec , 15 2023
1. Non rising stem gate valve: The stem nut is located inside the valve body and in direct contact with the medium. When opening and closing the gate, rotate the valve stem to achieve this. The advantage of this structure is that the height of the gate valve remains constant, so the installation space is small, making it suitable for gate valves with large diameters or limited installation space. ...

Can Gate Valves and Globe Valves Be Used Interchangeably?
Dec , 15 2023
Structurally Gate valves can rely on medium pressure to tightly close the sealing surface, thereby achieving the effect of no leakage. When opening and closing, the sealing surface of the valve core and valve seat always come into contact and rub against each other, so the sealing surface is prone to wear. When the gate valve is close, the pressure difference between the front and back of the pipe...

Analysis of Steam Valve Leakage due to Sealing
Dec , 15 2023
The sealing damage of the steam trap valve is the main cause of internal leakage of the valve. There are many reasons for valve sealing failure, among which the failure of the sealing pair composed of the valve core and valve seat is the main reason. There are many reasons that affect the damage of the valve sealing surface, including mechanical wear caused by incorrect selection, high-speed erosi...
