First, use and performance norms

Q41-ball valve suitable for medium and small diameter pipes of all kinds of pressure, temperature and media under the control of or access to pipelines cut off the gate dielectric devices; by media pressure to compress the ball valve seat on the export side, the use of Path pressure and subject to certain restrictions. Using 90 ° transmission, the switch to facilitate rapid, rapid can hoist.

Second, the operating principle and structure of the note

1, to facilitate the smooth ball-channel pipeline sweeping clean lines, transportation and solid particles such as size medium.

2, the use of PTFE （Teflon）, and other materials as a seal, good lubrication and elasticity, friction with the Department of small ball, long service life.

3, the gate quickly and simply hoist spheroid when they turn 90 °, convenient and fast.

4.’s Fluid resistance of small ball, the ball full-time channels, and connecting channels Body cross-sectional area equal to the pipeline and come into line, the ball flowing through media, which is equivalent to flow through a section of pipe in various types of Ball valves in the fluid path of least resistance.

5, equipped with manual, the worm gear drive, pneumatic, electrical （explosion） can achieve long-range automatic control, to meet the user’s request to use a variety of operating conditions.

Note: ≥ DN200 valve selection of more than fixed-Ball.

Fourth, size and shape of the main connection size:（浮動球）
