OutlineThe 10Q Series unbalanced shut-off valve adopts top guided pressure unbalanced plug. It is suitable for applications with low differential pressure. The plug and seat surfaces are subjected to hard alloy overlay welding to ensure long-time stable running of the valve. For shut-off applications of media of high temperature and service conditions with high differential pressure, we have specially designed the double-plug pressure relief type shut-off valve. The trim of this kind of valve adopts double-plug structure with flow to off design. When opening the valve, first open the small plug, and the starting force is relatively low because the area of thrust surface of the small plug is small. After the small plug is opened, the pressure after the valve is released and the differential pressure acting on the large plug is greatly reduced. The large plug can be opened with a relatively low actuator force. The trim of this kind of structure can meet the need for shut-off applications in service conditions with high differential pressure.

Outline The 10S Series unbalanced multi-stage pressure drop control valve is suitable for applications with high differential pressure and applications t hat produce flash evaporation and cavitation. According to the requirements in different service conditions, it is designed with various multi-hole cages that form a multi-stage pressure drop that form a multi-stage pressure drop trim, so that the internal energy of high trim, so that the internal energy of high speed media is consumed and flow velocity is reduced from the time when the fluids contact the first cage. As it is composed of various cages, the pressure is gradually reduced so that the medium pressure is always above the saturated vapor pressure, and the occurrence of flash evaporation and caitation is eliminated. The standard configuration is the unbalanced single- seat plug and the plug and seat are subjected to hardening treatment to prolong the service life of the trim. The valves of large sizes can be designed with the balanced single-seat plug structure.

Outline the 10s series multi-stage pressure drop control valve adopts the sleeve guided structure and pressure balanced plug. It is mainly used in service conditions with high differential pressure and applications that produce flash evaporation and cavitation. According to different parameters, it is designed with different pressure drop cages that form a multi-stage pressure drop trim. The cages designed according to different service conditions ensure the occurrence of flash evaporation and cavitation in the valve is eliminated. Throttling is carried out from the time when the media contact the first cage, and the high differential pressure at the inlet is gradually reduced after several times of throttling. Thus it is effectively ensured that the pressure is always above the saturated vapor pressure when the media flow in the valve, and the occurrence of flash evaporation and cavitation is eliminated, so that the service life of the control valve is prolonged under severe service conditions.

Outline The 10D Series multi-hole low noise control valve adopts the sleeve guided structure and pressure balanced plug. It is a high performance control valve with good dynamic stability that is suitable for severe service conditions. As the differentia l pressure in the service conditions is relatively high and the flow velocity of media is high, the trims will be severely eroded and damaged and high noise will be produced. Therefore, we change the standard window-type sleeve into the multi-hole sleeve. For liquids, the flow direction is generally high-in and low-out, and multi-hole throttling makes the media carry out collision inside the sleeve, so as to consume internal energy and reduce flow velocity . For gas media, the flow direction is generally low-in and high-out, so that the gas media achieve volume expansion at the back of the seat after throttling by the multi-hole sleeve and the pressure of media is reduced to lower the flow velocity. The parts of the101D Series are interchangeable with those of the 101T Series control valve except that the sleeve is changed into the multi-hole type.
