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. 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.

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.
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.
	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.

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:I'm going to put a solar energy and an electric water heater installed in the same hot water pipe, a valve, a valve open and close the valve B and vice versa the installation of solar and electric water heater, there can be no linkage valve?: In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.

Q:What are the definitions of internal, external and leakage valves?: The leakage within the valve that is the reason of erosion wear medium makes the valve is not closed tightly, even if the valve screw (stem) screwed in place, because there is still a gap between the spool and the valve body, the medium can flow past.

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.

Q:What is the difference between valve j941H-40 and j41H-40?: The difference is that one drive is electric, one is transmission, and the other is manual."Valve design manual" showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)More than one, 9, 9 fingers, electric, more than an electric.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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q:What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?: Pneumatic valve compared to the electric valve, the valve can be the same, rubber lined butterfly valve or other valves, pneumatic valve opening speed (Basic 1 second can be fully open), the price is lower than the electric valve. But there must be process air (4-6bar compressed air). According to my experience, if the scene has compressed air, it is recommended to use pneumatic valve, if there is no compressed air, it is recommended to use electric (electric valve expensive, open valve slow).

Q:Why is copper used in cryogenic valves?: Contact with water does not corrode easily。he influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!

Q:How to suppress the valve?: Upstairs is right... But look at the situation, there are some valve flange is 16 pressure, but the body can only play 10 pressure, there are cases.. Such as knives, valves and other ventilation valve

Q:In the decoration, I do not know where to get the valve, what kind of products should be bought?It is hard to fit the valve in the water inlet of the house. If not, can you? Will it have any effect on future use?: All inlet pipes should be fitted with valves, so if the faucet breaks, you'll know the benefits
