Parallel gate valves are classified as single gate plate or double gate plate It is classified into two types based on the thread position of the stem rising stem gate valves and non rising stem gate valves Advantages of a Rising Stem Gate Valve Fluid resistance is low and the sealing surface is eroded and eroded by medium
•The body and gate shall have guide surfaces to minimize wear of the gate seats during operation of the valve to accurately position the gate throughout the travel distance to its seat and to ensure the alignment of the gate and stem in
Gate valves have generally two seats one on the upper side and the other on the lower side The stem of a valve is used to open/close and the fluid as it moves the disc The stem is linked to the valve actuator or to the manual handwheel or lever at one end
