10S Series Control Valve

The 10S Series multi-stage pressure dropcontrol valve adopts the sleeve guided structure and pressure balanced plug. Itis mainly used in service conditions with high differential pressure andapplications that produce flash evaporation and cavitation. According todifferent parameters, it is designed with different pressure drop cages thatform a multi-stage pressure drop trim. The cages designed according todifferent service conditions ensure the occurrence of flash evaporation andcavitation in the valve is eliminated. Throttling is carried out from the timewhen the media contact the first cage, and the high differential pressure atthe inlet is gradually reduced after several times of throttling. Thus it iseffectively ensured that the pressure is always above the saturated vapor pressurewhen the media flow in the valve, and the occurrence of flash evaporation andcavitation is eliminated, so that the service life of the control valve isprolonged under severe service conditions.
