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.
 Steam Control Valve

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.
2.As for the single seat control valves with the bigger diameter, the unbalanced force and cost shall be calculated, because the unbalanced force, increases, the cost of the actuator will increases accordingly.
3.When the flow is big (exceed the Kv of the single seat control valve), then this series is not available any more.
4.Sometimes, the output force of actuators (especially the pneumatic actuator) from every factory is different.

 

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.
 Steam Control Valve1.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.
 Steam Control Valve1.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.

Q:Hydrant valve leaks, how do you close other valves? Specific steps?
Hello my name is Baidu know the long days of high water leakIn the vicinity of a common fire hydrant, there is a valve, which is convenient for fire hydrant maintenance, because fire hydrant repairs need to close the water source. Look around, it should be easy to find the valve. Switch valve is very simple, and the direction of the twist screw is the same, clockwise turn off, counterclockwise is open. Closed valve, fire hydrant will not leak, you can feel relieved to repair. I guess your fire hydrant is sealed rubber pad, aging causes leakage, it is a common disease of fire hydrants.
Q:What valves are needed on the construction site?
Order valves1, according to the use of place, use, and understand the relevant laws and regulations, specifications, standards, policies, approval may be used after the selection of valves suitable for various requirements;2, confirm the working conditions of valve, applicable medium, working pressure and medium temperature;3, determine the nominal diameter corresponding to the pipe: DN (mm), NPT, NPS (");4, determine the way to connect with the pipe: flange type, internal (external) thread type, welding type, clamp type, clamp type, card sleeve type, etc.;5, determine the valve operation mode of driving: manual, worm gear drive, pneumatic, electric, hydraulic, electromagnetic, electro hydraulic, etc.;6, confirm the types of valves: gate valve, globe valve, throttle valve, plunger valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, drain valve, pressure reducing valve and other special valves;7, determine the use of valves: switching type, adjustment type, safety type and so on;8, determine the valve shell and internal parts of the material: carbon steel, alloy steel, stainless steel, ductile iron, gray cast iron, copper alloy, aluminum alloy, plastic and so on;9, determine the valve sealing performance requirements, sealing level or sealing leakage;10, determine the valve coating requirements, packaging requirements, transportation requirements;11, special needs of the valve should also be determined: structure length, valve height, appearance size, flow resistance, emission capacity, flow characteristics, protection level, explosion-proof performance and other parameters;12, determine the valve installation position and posture.
Q:Which brand of electric valve is good?
The electric actuator imports now commonly used with Omar, Rotok, SIEMENS, you should still work to decide which Denso, such as regulating type? Switch mode? Intelligent? Regular type? There are valves can choose some well-known brands
Q:What does the PN on the valve mean?
1, mark "ON25" and "PN16" respectively what does that mean? 2, the valve above has an outer six corners, so PN16 refers to the nominal pressure of 16 kg valve. Valves on the fittings are standard parts, special
Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean?
1/2 is 4 points caliber, =15mm 1/4 is 2 points, caliber concise
Q:How about the quality of FITOK valves?
It's made in China. It's also made of foreign brands!Swagelok, Hoke, Parker, these three are foreign brands!
Q:How can the material be checked by valve approach? What experiments do you need?
Under normal circumstances, in the selection of the valve has been considered the main components of the valve material, the use of the valve to determine (for example, media, temperature, pressure, etc.), the valve can not change the material used. For higher or special purpose valves, in addition to the normal valve strength, sealing test, the main material must be used for the inspection and confirmation. The chemical composition and mechanical properties of the valve body, valve cover, sealing surface, valve stem, packing and sealing parts shall be examined. Samples can be taken in bulk or tested with test sticks attached to the product.
Q:What valve is the FCV?
It's FCU, Fan, Coil, Unit, fan coil valves
Q:What do you mean by "P54" in the valve z962y-p54 100V?
Applicable temperature 540 degrees centigrade;Applicable temperature 540 degrees centigrade
Q:What does the ZH41 valve ZH41 mean, and what other specifications?
Is the model wrong? The correct one should be Z41HGate valve, hand flange connection name, rod type single gate, sealing surface is alloy steel
