Ball valve open-close part for sphere, through a sphere around the body center for rotation to achieve open, closing a valve.Used for intercepting and change the flow distribution ratio or quick opening and closing.
Its characteristic is wear-resisting, good sealing, light switch, long service life.Widely used in petroleum, chemical industry, power generation, paper making, aerospace and other fields.
The advantages of the ball valve:
1, with the bottom flow resistance
2, realize completely sealed reaction in the high pressure and temperature range
3, can achieve rapid opening and closing and no impact to operation
4, not easy to get stuck at work, so reliably used in corrosive medium and low boiling point
5, double sealed more reliable
6, when the ball valve is fully open and close, sealing surface and the dielectric isolation, so the high speed won't bleed air seal face erosion by the media.
7, compact structure, light weight, can be thought of as the most ideal valve ball valve is used for low temperature medium.
8, all welded body ball valve, can be directly buried underground make internal valve from erosion, the highest service life can be up to 30 years.
Our advantage:
The company on the basis of combined with the structural advantages of ball valve, ball valve leakage protection aspects focus on improvement, the first is to use three free maintenance o-rings, adding self-styled mat, stainless steel valve stem to prevent rust and on both sides of a sphere with butterfly spring, easy to cause the medium leaking key protection area.And the company can according to customer demand, customized.
The company in the valve design and manufacturing of 32 national patents, ISO9001:2000 secondary quality system certification and CE, ANSI, UN and other international certification.Is the present domestic most professional heating valve manufacturing enterprise.
