Stainless Steel Ball Valve

Features and Benefits:

Full Port Design
Full port construction improves flow characteristics for greater process efficiencies
Blow-Out-Proof Stem
Stem is bottom loaded to prevent removal when valve is in service
Locking Device
Enables plant personnel to secure valve in open or closed position when manually operated
Live-Loaded Stem Packing
Provides constant load on the stem seal and extends service life
Corrosion Resistant
Made of 316 stainless steel (A351 Gr. CF8M) for greater chemical resistance and longer service life

Application:

Offshore / Oil / Gas / Chemical / Water / Wastewater / Marine

Notes

The specifications can be designed and satisfied for customers’ special requirements. The product is designed by adopting L.Lai’s high technologies. We have obtained certificates of SGS ISO 9001:2008.

Q: Hard sealing ball valve, what method can calculate the leakage? How much is grade 4? How much is grade 5? How much is level 6? For example: how many DN150 seals are 5 ml?: Valve leakage level is actually the valve sealing class. There are two kinds of GB and American Standard.

Q: The working principle of the track type ball valve: With its unique structure, the spool rotation separation open, new technology design of mechanical seal pressure, is the most prominent advantages of the sealing surface does not produce friction, long service life, low operation torque, even if the medium water content of solid particles, sediment, short fiber and other impurities, high concentration fluid flushing sealing condition of body harsh, can maintain good sealing, to ensure the engineering equipment maintenance period in the safe and reliable operation.

Q: What does W represent in copper ball valve Q11W-16T?: According to the provisions of the JB/T 308-2004 valve type programming method:Q== ball valve1== connection: internal thread1== ball valve structure: straight through flowW== sealing surface material: body. That is, the sealing material is the same as the body material-16== pressure rating: 1.6MPaT== body material: copper or copper alloy

Q: DN15 ball valve with a bit of outer wire: Is. But we usually use engineering diameter in our country. A few is the imperial system, in addition to the domestic veteran workers still use, and now are using GB size.

Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?: Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of universal caliber. The pipes with the same nominal diameter can be connected with each other, so they are interchangeable. It is not the actual diameter or diameter of the pipe, although its value is close to or equal to the diameter of the pipe.In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.Nominal outer diameter is expressed by DN, refers to the outer diameter of the pipe. Such as the outer diameter of 32mm PVC-U pipe can be expressed as dn32. The specification of PVC-U pipe for building drainage is indicated by DN (nominal outer diameter) * e (pipe wall thickness) (GB-T, 5836.1-2006).

Q: Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!: This is a manual ball valve three simple when meet your requirements is L ball valve

Q: How to distinguish between cold water valve and hot water ball valve?: Each of the valves has a sign on which the temperature and pressure are applied.There's something wrong with your question: what's the difference between a cold water valve and a hot water ball valve?Domestic valves, such as cut-off valves, cold water using the valve core, sealing materials, rubber, that is, cold water.Ball valve sealing surface is generally PTFE, can be used for hot water.

Q: What's English for ball valves?: Check valve/ball vavle/globe valve (ball valve), there are three kinds of translation, see which you preferFast stainless steel ball valve, ball valve is evolved from the plug valve. It has the same rotation, 90 degrees lifting action, and the difference is that the cock body is a sphere and has a circular through hole or passage through its axis. The ratio of the sphere to the channel opening should be this, i.e., when the ball rotates 90 degrees, the spherical surface should be fully presented at the inlet and outlet, thus truncating the flow. The ball valve only needs to rotate 90 degrees of operation and very small turning moment can close tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel. It is generally believed that the ball valve is suitable for direct opening and closing, but the development of the ball valve has been designed to make it throttling and controlling the flow.

Q: That is to say, there is still a difference The man in the workshop said it was one thing... It's completely confusedHere are the data for the two valves. Please consult with the experts.Ball plug valve, high temperature cast steel, A216Gr.WCB flange, two pass, full quantity type 3, X 150LB RF ball / rod, 13%Cr seat, PTFE handle openBall valve Q41F-150LB-3": Ball valve refers to the valve for the sphere of the valve, the English BALL VALVE, ball plug valve should be said that the plug valve, the disc is like a plug like, PLUG VALVE in english,

Q: What does copper ball valve mean by "1/2"?: 1/2 is inch inch, which is what is usually called "valve", and the caliber is "DN15". You can see the contrast chart of the valve diameter and inch.
