Product Presentation:

Pressure and temperature class: ANSI B16.34 E101 test and inspection: GB/ t598 E101 product definition: GB/ t21465-2008 (1) special seal at ball point (to prevent internal leakage) : seat packing:Polyformaldehyde sealing, excellent performance is under great pressure, in order to adapt to cold weather, can add a certain proportion in polyformaldehyde manganese dioxide, can make the temperature range of - 40 ℃ ~ + 200 ℃. Anti-corrosion metal group:In the compressed gas industry, valve in the open when the pressure is very high, especially the compressed natural gas, usually containing impurities (gas after filtering, impurity content is still on the high side), gas in the process of circulation of ball valve, under the action of high pressure, gas temperature rise quickly make soft polyformaldehyde body sealing, which made the impurity in the gas under the impact of the high pressure, it is easy to through the body sealing, cut seal, and cause gas leak. So the special design of polyformaldehyde sealing and anti-corrosion metal skirts, ensures that in the presence of the above situation,Avoid direct contact with the gas polyformaldehyde valve body seal (gas contact is above the metal seal), so as to ensure the maximum sealing effect of the ball valve, to prevent internal leakage.

Technical parameters：

1.Fluid resistance is small, full diameter ball valve basically no flow resistance.

2.Simple structure, small size and 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 closed, the ball and seat sealing surface is isolated from the media, the media through, will not cause erosion of the valve sealing surface.

7.Suitable for a wide range of applications, from small to a few millimeters, large to a few meters, from high vacuum to high pressure applications.

8.The ball valve can be used in medium with suspended solids due to its wipeability during opening and closing
