◆ obstruction and discharge: When the valve is turned off, on the downstream side of the seat so that the liquid blocked, the body cavity of the accumulated matters in the discharge device can be excreted.
◆ automatic pressure relief structure: among the abnormal increase of the phenomenon of cavity pressure, the medium in the cavity can depend on their thrust to promote the automatic pressure relief valve seat and to ensure the safety valves provided.
◆ reliable stem seal: valve stem seal downloading inverted structure, inverted sealed with sealing force increases with increasing media pressure, it can ensure a reliable stem sealing, and, when an abnormal pressure when the valve stem not emit.
◆ Fire Structure: According to the conditions and needs of users, the ball valve can be designed for structural fire protection. API607 fire ball valve design and implementation of the provisions of other standards JB/T6899, once leaving the soft ring of fire burning, the valve structure can prevent the fire a large number of media leaks, to prevent further expansion of the fire.
◆ Anti-static structure: When the operation of the valve, due to friction between the ball and seat, will have cattle and the accumulation of electrostatic charge on the sphere, in order to prevent static sparks, especially in the valve set on static devices, will accumulate in export charge on the sphere.
The whole structure and the reduced diameter Path Structure: In order to meet the different needs of users, the company has full bore ball valve products and the reduced diameter of two series. Ball Valve Full Bore diameter and pipe diameter the same channel for easy cleaning, and reduced diameter series ball relatively light weight, but the flow resistance of the same caliber valve is only 1 / 7 or so, it is the application of reduced diameter series ball prospects are more promising.
