BT310 Light Load Triple Eccentric Butterfly Valve

BT310 valve body and valve plate are both welded with steel plate, with triple eccentric structure. Its scope of application has been able to bear pressure up to 100 pounds, low temperature to -196 ℃, up to 700 ℃, sealed to reach 0 leakage and the control ratio of up to 100:1. That is to say, in a variety of harsh and critical process control line, you can now safely use butterfly valve, regardless of the switching valve and control valve, as long as appropriate selection of type, and the cost is low. Is widely used in occasions where medium temperature is less than or equal to 425 in metallurgy, electric power, petrochemical, and industrial pipeline to the drainage and municipal construction and others, in order to adjust the flow and set off a fluid. Material is divided into: cast iron, cast steel and stainless steel.

Performance Characteristics

1, The hard sealing butterfly valve uses triple eccentric hard sealing structure. The valve seat and the valve plate almost don’t wear, providing the function that the more closed, the tighter searling.
2, The sealing ring is made of stainless steel and multi-level flexible graphite, with the dual advantages of metal seal and the elastic seal. It has excellent sealing performance both in the low and high temperature. It is corrosion resistant, and has long life and other characteristics.
3, The sealing surface of the butterfly plate is welded with cobalt base hard alloy. It is wear resistant, and the service life is long.
4,Large scale lattice structure, high strength, large flow area, small flow resistance.
5,According to user needs, hard seal butterfly valve can be designed with a two-way sealing function. Installation is not limited by the flow of media, nor the impact of space, and can be installed in any direction.

Product Advantage

1,The valve seal ring is made of stainless steel plate and laminated graphite sheet, which can effectively prevent the effect of small solid in the medium and sealing of surface occlusal caused thermal expansion. Even with minor damage, it does not produce leakage.
2, As the seal ring is a special design for detachable, even if the seal ring damages and leakage becomes large, the requirements of sealing can still be achieved by changing the sealing way.
