Product Description:
Q41H/Q41Y manual floating hard seal ball valve ball and seat metal-to-metal seal, the seat of the plate spring loaded sealing structure, a breakthrough in the use of soft sealing ball valves with low temperature and not applicable to the limitations of the media with particles. Hard seal ball valves are used in high temperature and high pressure water, steam, oil, viscous and particulate media devices and pipelines. Especially suitable for the medium is viscous, containing particles, fibre nature of the occasion. Widely used in petroleum, chemical, teaching equipment, light industry, high-pressure equipment, pharmaceutical, paper and other industrial automatic control systems.

Product features:
1、The valve seat adopts plate spring loading sealing structure, which can use higher temperature and medium with granularity;
2、Using down-loaded valve stem and equipped with inverted sealing structure, it can ensure reliable sealing at packing;
3, the ball can be designed as an anti-static structure, in the ball and stem, stem and valve body between the conductive spring, to avoid static ignition ignition of flammable substances, to ensure system safety;
4, the ball and sealing surface using nitriding, surfacing, spraying and other ways of treatment, can be applied to different process requirements;
5, the ball valve seat can be set at the auxiliary sealing structure, in the valve seat and stem parts of the addition of grease injection valve, emergency can be temporarily sealed, and according to the need to lengthen the valve stem in order to be suitable for buried laying place;
6、Pneumatic actuator and electric actuator can be added to achieve centralised control and remote control.
7、Advanced valve seat: gathered many years of experience in manufacturing ball valves and design of the valve seat to ensure that the valve sealing, low friction coefficient, small operating torque, a variety of seat materials, adapt to a wide range.
8, switch the handle without error: the use of flat stem, and the connection of the handle will not be misplaced, thus ensuring that the handle indicates the switch state and the valve a speech.
9, locking device: in order to prevent the valve switch misoperation, in the valve fully open, fully closed position has a locking hole, to ensure that the valve is in the right position.
10、Stem anti-flying structure: the valve stem is under mounted, to prevent pressure flying out, at the same time can be after the fire, and the valve body to form a metal contact, to ensure that the valve stem sealing

球阀安装注意事项:

1.安装施工必须小心，切忌撞击阀门。
2.安装前，应将球阀作一检查，核对规格型号，鉴定有无损坏，尤其对于阀杆。还要转动几下，看是否歪斜，因为运输过程中，最易撞歪阀杆。还要清除阀内的杂物。
3.球阀起吊时，绳子不要系在手轮或阀杆上，以免损坏这些部件，应该系在阀体上。
4.对于球阀所连接的管路，一定要清扫干净。可用压缩空气吹去氧化铁屑、泥砂、焊渣和其他杂物。这些杂物，不但容易擦伤球阀的密封面，其中大颗粒杂物（如焊渣），还能堵死小阀门，使其失效。
5.安装时要留有阀柄旋转的位置。6.球阀不能用作节流。 7.带传动机构的球阀应直立安装。
