GV130 GV130 Top Guided Single Seated Control Valves (Balanced)

GV130 series top guided single seated control valve which applied with P single seat plug with pressure balanced fluid, can bear big working pressure difference.The dynamic stability of the control valve is improved due to the use of balanced seal ring. This series is suitable for the occasions with fluid containing some impurity particles, and can reduce plug stuck.

Product Details:


12-1


Features

1, Can work in occasions with higher pressure difference despite the characteristic of GV120(unbalanced plug)

2, With small unbalanced force,large allowing pressure difference,stable operation due to the use of balanced plug 


Benefits    

1, The structure is relatively simple so it is suitable for occasions with particle impurities, and can reduce stuck

2, Compared with GV120 (unbalanced Plug),the required thrust is smaller in the same closing pressure, so a film head with smaller thrust can be selected to lower the cost.
