[ball valve] features :
(1) small fluid resistance, full diameter ball valve basically no flow resistance.
(2) simple structure, small size, light weight.(3) tight and reliable.It has two sealing surface, and the sealing surface material of the ball valve is widely used in all kinds of plastics at present.It is also widely used in vacuum systems.
(4) easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.
(5) easy maintenance, ball valve structure is simple, the sealing ring is generally mobile, disassembly and replacement are more convenient.
(6) in full open or full closed, the sealing surface of the ball and the seat is isolated from the medium. When the medium passes through, it will not cause erosion of the sealing surface of the valve.
(7) wide application range, from small to a few millimeters in diameter to a few meters, from high vacuum to high pressure can be applied.(8) since the ball valve is wipeable during opening and closing, it can be used in medium with suspended solid particles.

Two-piece ball valve overview:

Q11F flanged ball valve and flanged gate valve are the same type of valve.It is mainly used to cut off, distribute and change the flow direction of medium in pipeline.【 one-piece internal thread ball valve 】【 two-piece internal thread ball valve 】【 three-piece internal thread ball valve 】 is a new type of valve widely used in recent years.

Technical parameters of two-piece ball valve:

(1) nominal pressure: 1.6-6.4mpa

(2) the applicable range of stability: - 20 ~ 232 ℃ ~ 350 ℃

(3) applicable medium: water, oil, gas and some corrosive liquid (W.O.G)

(4) thread type: G.The NPT.BSPT.BSP.DI259/2999
