Product description of top guide control valve :
The single-seat control valve adopts fluid pressure balanced valve core structure. It can be withstand high working pressure differentials. At the same time, it uses a balanced sealing ring to make the control valve dynamic stability better with the 202MP cage single seat adjustment. Compared with the valve, it is more suitable for the occasion that the fluid contains some particulate impurities, and it is not easy to cause the spool to jam.
