Q:What is the difference between valve j941H-40 and j41H-40?
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)According to the comparison, we can see that the difference is that one drive mode is electric, one is transmission mode, and the other is manual. What do not understand, you can ask me directly. Two hundred and fourteen million two hundred and seventy-seven thousand eight hundred and fifty-one
Q:What does the RF of the valve mean?
The RF of the valve represents the form of the sealing surface, which means: protrusion.
Q:What's the difference between valves and valves without valves?
In that regard, some valves are one-way valves, only out of the can
Q:Several problems about valve parameters
FV or LV on the flow chart, which represents the instrument bit number, FV is flow valve, and LV is level valve.The valve on the nameplate CV value, it is a measure of the size of the valve flow, it is the concept of 40 - 60 degrees Fahrenheit in the water, the pressure drop of 1 psi, in a valve opening per minute flow through the valve (U.S. gallons).
Q:How do you calculate the pressure difference between the front and rear of the valve?
the preset pressure after the valve, thus maintaining the dynamic pressure balance valve, and non compressible medium, mainly for the purpose of regulating the flow, especially in the petrochemical industry, power industry, if the specific calculation of a valve is more difficult, but a lot of data will provide the valve valve opening and flow of the corresponding graph, the landlord is really interested in learning more, can go to the Xinhua Bookstore to find the valve selection manual valve related content, which will introduce calculation method.
Q:What does valve 41F-40C mean?
Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
Q:What do you mean by the 16 bit coding of the valve type?
What kind of coding do you mean? Valve type? Stress? Do you have these?Profit ZF43Y-250C-DN50.. Do you mean this one? ZF43Y valve type. Flat gate valve250C. Refers to the 250 pressure, C is carbon steel, DN50 refers to the caliber of the valve specificationsI hope you mean this one
Q:How to open the gas valve?
General domestic weather is more ball valve, counterclockwise turn 90 degrees can.
Q:Is there any difference between the valve and the water valve?
Oil valve with water valve is that the oil valve is over the oil, and the valve is over water, the type of fluid is not the same.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 difference between the adjustable range of valve 50:1 and 100:1?
Adjustable ratio is also called adjustable range, if to R to indicate, then R=Qmax/Qmin should pay attention to the minimum flow, Qmin and leakage of different meanings. The minimum flow refers to the lower limit of adjustable value, it is generally the maximum flow rate of Qmax 2%~4%, and the leakage is fully closed when the leak valve, it is only the maximum flow rate of 0.1%~0.01%.Adjustable range 100:1 generally can not reach, the accuracy of this valve is very high.
