ball valve

Q47 type fixed ball valve is a new generation of high-performance ball valve, suitable for long distance pipeline and general industrial pipeline, its strength, security, and resistance to bad environment, special consideration when the design is suitable for all kinds of corrosive and non corrosive medium.Compared with the floating ball valve, it works, the fluid pressure in front of the sphere of all is passed to the bearing force, will not make a sphere to the seat to move, so the seat will not bear too much pressure, so the fixed ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life, applicable to high pressure, large diameter.Advanced spring seat components, since the tight characteristics, realize the upstream sealing.Each valve has two seats, each direction can be sealed, and therefore there is no flow restriction, installation is two-way. 

This valve has two and three type two kinds of body structure, the flange bolting, seal enhanced ptfe inserted into the stainless steel ring, steel ring at the back of the seat close to the ball, no spring guarantee seal.Up and down the stem are no PTFE bearing, reduce friction, easy operation, small no TAB at the bottom of the shaft, to ensure that the ball and seal it.All sizes available: valve flow aperture is consistent with the pipeline diameter, so that pipeline cleaning.

Q47H type fixed ball valve product features

1, using cylindrical spring or waveform spring preload Lian metal valve seat structure, sealing design reasonable pretightening, closed and flexible, effectively guarantee the reliability of the seal.
2, the use of special structure device of the valve stem, leakage will not only make sure to fill in material, and prevent the stem out.
3, according to the needs of users, can be designed to adapt to the dust, including containing solid particles, the structure of the serous luid etc, make the valve wear resistant and high temperature resistant performance is better.
4, itself with fire retardant anti-static function.
5, the structure of ball valve shall be in accordance with the provisions, to use.
