Metal-to-Metal Seal Ball Valves

Q:What does 1000WOG mean on a ball screw valve?: It's also a standard, huh?

Q:What's English for ball valves?: Mechanical introductionThe main characteristics of the electric ball valve of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integrated, or can be combination. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of flow medium. Ball valve is a new type of valve widely adopted in recent years. The resistance of fluid is small, and its resistance coefficient is equal to that of pipe of same length.The ball valve is simple in structure, small in size and light in weight. Tight and reliable, at present, the ball valve sealing surface materials widely used in plastic, good sealing, vacuum systems have been widely used. Convenient operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. Easy maintenance, ball valve structure is simple, the sealing ring is generally movable, disassembly and replacement are more convenient. In full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, will not cause the valve sealing surface erosion. Wide range of applications, from a few millimeters to a few millimeters, large to a few meters, from high vacuum, high pressure can be applied.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. The main features of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integrated, or can be combination.

Q:Which one is more durable?: Where can I distinguish it from the handle?!!In simple terms, the heavy ones need to wear a little longer

Q:Stainless steel ball valve Q11F-10P 16P each letter meaning?: Q ball valve, the first 1 representatives of second representatives of 1 screw connection, ball valve floating ball (ball valve floating ball and fixed ball, 7 ball, F fixed on behalf of) on behalf of PTFE- PTFE seal (PTFE PTFE), representing 10 of the nominal pressure valve is 10 kg (1Mpa), P represents the ball body material is 304 stainless steel.Shanghai blue forest control valve Co., Ltd.

Q:The valve nominal 1/2, 3/4 is how much?: Nominal diameter 1/2 3/4 corresponding to DN15 DN20

Q:The working principle of the track type ball valve: No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.

Q:3/43/8 above the ball valve is not usually said of the big ball valve?: That is the calculation of the imperial, generally divided into two types, 1 inch (in.) 2, metric (mm) swap inch metric 1/4 (2) =6 3/8 (3) =10 1/2 (4) =12 5/8 (5) =16 3/4 (6) =18 7/8 (7) =22 1 1/8 (1 inch 1) =28,

Q:Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ: This does not mean cast steel can not be used. Cast steel is also acceptable because all the check valves and control valves of natural gas lines are cast. But the casting process has a high probability of defects.

Q:Are ball valves and float valves a thing?: Ball valves and float valves are not a thing.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. floating ball valve is a ball without supporting shaft, the sphere was two seat clamping, which is "floating" state, it is mainly used in the pipeline to cut off, distribution and change the direction of media flow. Floating ball valve mainly has seat seal design, reliable reverse sealing valve, sealing rod, fireproof electrostatic function, automatic pressure relief and locking device and other structural features.

Q:Flange ball valve Q41P3-150C2, DN50, RF, WCB/316 hardening, each letter number represents what?: Q-- ball valve; 4-- flange connection floating structure; 1---; P--- sealing material: boroning steel; nominal pressure 150:--- 15MPa;C--- body material: carbon steel; DN50--- nominal diameter; RF--- flange sealing form (convex flange); WCB--- carbon steel castings; 316---- austenitic stainless steel
