Q: Remove the handle and lever the stem rotation with a wrench,: 1, carbon steel (WCA, WCB, WCC) applies to working temperature between -29 ~ 425 degrees between the middle and high pressure valve. Used for superheated steam. High temperature and low temperature oil, liquefied gas, compressed air, water, natural gas and other media.2 、 low temperature carbon steel (LCB) is suitable for working temperature between -46 ~ 345 Degrees of low temperature valve.3, alloy steel WC6, WC9 is suitable for the working temperature -29 to 595 degrees between the non corrosive medium high temperature and high pressure C5, C12, C12A for working temperature -29 to 650 degrees between the corrosive medium high temperature and high pressure valve.4 austenitic stainless steel for working temperature between -196 ~ 600 degrees corrosion of any medium valve.5,

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: What's the difference between valves and valves without valves?: The difference between a valve with and without a valve is that it has the advantage of having the valve exhaust. The advantage of the valve is that it can control the amount of exhaust and prevent the discharge of other fluids.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 valve?: The definition of a valve "valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device that flows or stops the medium (liquid, gas, powder) in a pipe and equipment and controls its flow. Valve is the control component of pipeline fluid transportation system. It is used to change the passage section and medium flow direction, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow, pressure relief, etc.. For fluid control valves, valve from the simplest to the most various valves automatic control system used in complex, its many varieties and specifications, the valve nominal diameter from industrial piping and instrumentation valves tiny tolarge diameter 10m valve. The valve can be used for the control of water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa ultra high pressure, working temperature from ultra low temperature to high temperature of 1430 DEG -269. Control valve can be a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic dynamic, electromagnetic hydraulic, electric hydraulic, pneumatic and hydraulic, gear, bevel gear drive; in pressure, temperature or other forms of sensor signals under the action according to the requirements. Or do not rely on a simple sensor signals to open or close the valve on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding, rotating or turning motion, thus changing the size of the flow area to achieve its control function.

Q: What does the valve specification "3/4CL150" mean?: Size: DN20 pressure rating: 150 pounds American Standard

Q: How to check the quality of the valve?: First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level. Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem. Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.

Q: Where is it installed, what is the role, what is the material, and are there other alternatives instead of this effect?: Main stem to prevent leakage, there are PTFE and graphite and so on. There are no other good products to replace.

Q: What are mine valves?: You want to see what works on the use of what media, in the choice of what type of valve is more appropriate. Shanghai HuquanValve manufacturers, veteran enterprises, trustworthy.

Q: What is the KVS in the valve parameter?: KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
