Product Description:

Metal-to-Metal Seal Ball Valves

Metal-to-Metal Seal Ball Valves are usually used in the industrial controlling pipeline services of high pressure, high temperature, severe corrosion and solid material containing industry, such as coal chemical, polysilicon and vitriol/ nitric acid. The leakage rate of metal-to-metal seal control ball valves can reach rate V. Top flange is designed per ISO5211 for easy amount various type of actuator.

Q:How to distinguish between cold water valve and hot water ball valve?
By the way, do you only require the working medium of the valve, general cold water and hot water?;Can provide the next 1, the valve's general use temperature of 2, whether the media granular impuritiesBoiling hot water is only 100 degrees; general, general valve can reach this use conditions,So cold water and hot water can choose the same type of valveI think the valve you want to know is not the drinking water valve you use at school?
Q:What's the meaning of the ball valve bore 14 "x 12"?
The inner diameter of the two ends of the ball valve is 14 inches at one end and 12 inches at the other.
Q:What is a high handle ball valve? What's the difference between it and ordinary ball valve?
the valve handle can extend out of the insulation material, convenient operation.
Q:Daily maintenance of ball valve
Longer service life and maintenance free period will depend on several factors: normal working conditions, maintaining a consistent temperature / pressure ratio, and reasonable corrosion dataBall valve in the closed state, there is still pressure fluid inside the valve bodyRemove the line pressure before servicing and leave the valve in the open positionDisconnect the power or air supply before servicingBefore the maintenance, remove the actuating mechanism from the bracketMust be found on the ball valve, the downstream pipeline has been removable pressure, in order to disassemble, disassemble operationIt is important to be careful not to damage the sealing surfaces of the parts, especially non-metallic parts, to remove the O rings. Use special tools when taking apart and re assemblingWhen assembling, the bolts on the flange must be symmetrical and tightened gradually and evenlyThe cleaning agent should be compatible with rubber, plastic, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned by using gasoline (GB484-89). Non metallic parts are cleaned with pure water or alcoholThe non-metallic parts should be removed from the cleaning agent immediately after cleaning and should not be soaked for a long timeNeed to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution
Q:Our factory has some ball valves in the direction of movement and normal ball valve is the opposite direction
Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it
Q:Q4110 what is the ball valve? What does each number stand for?
It's Q41-10Q- stands for ball valves; 4- stands for connecting flanges; 1- is straight through floating ball; 10 means valve bore 10If it's Q4110, you're not sure
Q:Ball valve use?
Ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and play a decisive role in the national economy.
Q:What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?
Two, characteristicsThe eccentric hemisphere valve is mounted type structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.Eccentric semi spherical valve is single valve seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.Low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.No friction at opening and closing. This function completely solves the problem that the traditional [wiki] valve [/wiki] affects the sealing because of the friction between the sealing surfaces.Wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.The self-cleaning structure eccentric semi ball valve sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.
Q:What brand of double live catch valve is good?
Different brands of PPR products can be connected, but in order to facilitate after-sales service, it is best to choose the same brand products.
Q:What's the advantage of using an electric ball valve?
Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.
