The Series G4 control valves are engineered specifically for critical anti-cavitation and low noise applications on liquids, gases or steam. Multi-stage controls flowing velocities in the valve trim by forcing the process fluid to follow a tortuous path of right-angle turns. The resistance to flow provided by these turns reduces fluid velocities significantly. Therefore, a vena contracta is never formed inthe trim and noise and cavitation are stopped before they can start.

Note:The G4 series can not been used in the medium contains large solid particles.

The Series G5 Pilot-operated cage control valves provide unmatched tight shut-off performance for high temperature applications(Working temperature ＞230℃).Compared with G2 series control valve this series has better sealing performace under high temperature conditions. In high temperature and high pressure conditions, even if the seat has a small leaking can also cause seriously erosion of the plug and seat. Therefore the control valves has good sealing performance is very important in these cases.The general method to improve the sealing performace is to increase the actuator size,However the pilot operated cage guided control valve improving the sealing performace by the pressure difference between lnlet and outlet of the valve, this structure can reduce the size of the actuator and improve the sealing performace.

The G6 Regulating and Cut-off Control Valve adopts the cage guided pressure balanced trim structure.Compared with the G1 series control valve, the only difference is that this series control valve adopts the soft seat structure, which can meet the requirements of the regulation and cutting in the same time.Inserting PTFE or RTFE soft seal material in the seat, it can achieve the zero leakage class.

G7 Cut-Off Control Valve adopts the cage guided pressure balanced trim structure. Compared with G6 series the only difference is in the design of the cage adjustment window, the flow characteristics of this series is quick opening it do not have the flow regulation function, can only meet the requirements of cutting off. Inserting PTFE or RTFE soft seal material in the seat, it can achieve the zero leakage class.

Mixing Control Valve is mainly used for mixing two fluids into a third fluid. Diverting Control Valve is mainly used for diverting one fluid into two fluids.

With control of the 3-way valve, when one circulation area between the plug and the valve seat gasket increases, the other one would decrease. The series can replace two mutual switch valve, and they can be applied to the control of liquid, gas, steam etc.

M1 Manual Control Valve is mainly used in the site where there is no electrical system or where precise control is not required.

A1 Angle Type Control Valve and globe straight control has the similar internal structure,the only difference is the valve body type.Its flow path is simple, it can effectively prevent the blocking of the medium,meanwhile the flow resistance is small. It is suitable for the medium of high viscosity or the medium contains particles.

D01 Pressure reducing regulators provide a desired and constant downstream pressure,even though the upstream pressure changes.The pressure which the regulators maintain we call it setting point pressure.For the pressure reducing regulators the valve closes when the downstream pressure rises and opens when the downstream drops.
