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:Who knows a door valve heating valve how to open?
The valve has a device like a cylinder lock that opens with a special key.The heating valve refers only to a radiator system accessories, is a type of valve, the valve commonly used heating system on the market is mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, regulator valve, relief valve, pneumatic control valve.
Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
Q:What are the main equipments for valve production?
I know these gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, check valves, and throttle valves
Q:What does the valve QF mean?
Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
Q:How to check if the gas valve is open?
The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..Chasing the answerThe valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..
Q:Our company is doing valve exports,
If the customs clearance order is required, the boxes, invoices, and contracts will not be needed. If the customs clearance is made, which port should be provided, the value of the goods, the weight, and the HS code for those
Q:What does 3/4''mean in the name of the valve?
Upstairs answer is very clear, 3/4 refers to the caliber of the valve is 3/4 inches, equal to the national standard DN20, (20mm) commonly known as 6 points. The most common family is 1/2, equal to DN15, commonly known as 4 points. Another marked 1.6 refers to the pressure of 1.6Mpa., equal to 16Kg, to bear the pressure.
Q:How does the valve close?
Rotate it, turn it clockwise. Spherical valve, then hit a cross shaped on the line.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Q:What is the main function of the valve?

Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
