SINGLE SEAT CONTROL VALVE | |
The structure of the single seat control valve series is the simplest among all the kinds of control valves, with the accurate flow characteristic, lightest weight and most widely usage. The advantages of this series valves has least leakage, and less pressure reduction losses than the cage and double seat control valves. If the allowable pressure is available, the single seat control valves shall be the first option compare to the cage or double seat kinds. | |
![]() | FEATURES: 1.Compare to other kinds valves, the single seat valve usually has the bigger unbalanced force (Ft) when it closed, so the matched actuator must have the enough output force, if the working condition is beyond the allowable pressure, do not choose the single seat valves as possible. |
DOUBLE SEAT CONTROL VALVE | |
There are two units’ seat, plugs and sealing surface in the normal type double seat control valves, while as for the cage type, it also has two units sealing surface, but it only has one plug. Because of the two flow channel, so the flow capacity (flow efficiency Kv) of the double seat control valves are bigger than the single seat type, but the leakage grade is lower than the single seat type, it is usually grade II, at most grade III. | |
![]() | 1.Forbid to choose the double seat control valves for the conditions of small opening and small flow capacity. 2.If the single seat type or cage type is available for the working condition, do not choose the double seat control valves. 3.As for the control valve with the diameter DN is bigger than 250mm, choose the rotatory valve ( V-shaped ball valve, butterfly valves, eccentric valves) to replace the double seat control valves if possible, otherwise there is a requirement of precise flow characteristic. 4.There is big leakage for the double seat control valve, consider cautiously before opting. |
CAGE TYPE CONTROL VALVE | |
The structure of the cage type control valve series is the relative simpler among all the kinds of control valves with the accurate flow characteristic. Besides the single seat control valve, the cage type control valve is secondly most used among all the kinds of control valves. It plays an important role in the nine kinds control valves types, in one project, the quantity of the cage type valves some time will exceeds 60% among all the control valves. | |
![]() | 1.Because of the balanced plug, this series valves are able to bear big differential pressure, while the matched output force from the actuator is relatively small. 2.Because of the balanced plug, this series valve can be operated stably without frequent vibration. 3.The windows on the cage are deployed symmetrically, the total flow kinetic energy consumes in the core of the cage, so the other inside partare not easy to be damaged, then the noise is lower, the working life is longer. 4.The windows on the cage can be made to meet different flow characteristic according to the working requirement, so the valves with same diameter are able to meet many different requirement of flow capacity CV. |
SELF-OPERATED REGULATOR | |
The self-operated pressure regulator is a kind which does not need outside power but take advantage of the power from medium to act and adjust by itself. The most notable feature of this series regulator is that it can be used in the working place without the electricity and gas supplying, which saves the power at the same time. In the specific range, the pressure setting can be adjusted at will.So it can be widely used in many fields like petroleum, chemical,electricity, metallurgy, food, textile, machinery and civilian building and so on to reduce/release or stabilize the pressure of the gas, steam and liquid and so on. | |
