What is a Vacuum Valve? A vacuum valve refers to the vacuum system components used to change airflow direction, adjust the airflow, cut off, or connect a pipeline in a vacuum system. It refers to valves with working pressure below standard atmospheric pressure. Vacuum valve components are sealed with a rubber sealing ring or metal […]
Read moreWhat Are the Applications of Sanitary Shut-off Valve?
What is a sanitary shut-off valve? A sanitary shut-off valve is a kind of mandatory sealed valve. When the valve is closed, pressure must be applied to the valve gate to ensure the sealing surface doesn’t leak. When the medium enters the valve from below the valve gate, the resistance the operating force needs to overcome […]
Read moreThe Improvement on Sealing Structure of Shut-off Valve
The shut-off valve has a simple structure. It can open or shut off the valve and ensure the valve’s sealing and upper sealing function through the mechanism of the valve stem being able to both rotate and lift. Due to the special movement mechanism of this type of structure, it has adverse consequences on the […]
