ball ball valve is used with a circular channels as opening and closing, the sphere with the valve rod rotation realize on-off movement. ball valve is rotated 90 degrees, the cock body for a sphere, a round hole or tunnel through its axis. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly. Ball valve can be divided into: floating ball ball valve and the fixed ball ball valve, V type ball valve, sulfur discharge ball valve, ball valve, plastic ball valve, card sets of ball valves, welding ball valve, air valve, one-piece ball valve, chip ball valves, threaded ball Industrial Valves, through ball valve, three-way ball valve, four-way valves, insulation ball valve, ball valve, pipeline ball valve, rail cant ball Industrial Valves, anti-corrosion ball valve, etc. Main standards, specifications, and common ball valve parameters: 1, the ball valve pressure rating: PN1. 0 - 32. 0MPa、150LB- 900LB、JIS10- 20 k 2, ball valve nominal diameter: DN6 - DN800 1/4" - - - - - - 36' 3, ball screw thread standard: G thread, mid-december, thread, such as NPT thread, BSPT thread 4, ball valve connection mode: flange, butt welding, thread, socket welding, welding, such as card sets of 5, ball valve, applicable temperature: - 196℃- 0 ℃ 0 ℃ ~ 540 ℃, 6 ball valve drive mode: manual, worm gear and worm drive, pneumatic, electric, hydraulic, pneumatic, hydraulic linkage, electro-hydraulic linkage 7, the valve body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8, 304). 、CF3( 304L) 、CF8M( 316). 、CF3M ( 316 l) , chrome molybdenum steel towers ball valve Industrial Valves materials can choose according to use media, can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media.

In an age when double flanged gate valve is increasingly important, the researchers believe manufacturers should pay close attention to their results.
No, this isn't a wonder product and it won't be likely to change your life but it will give your os&y gate valve a kick and bring the extraordinary to the every day. give it a shot at Mech Valve.
To ensure desired results, it is very essential that you get the right kind of from a certified provider..
