3-pcs stainless steel Ball Valve

3-pcs stainless steel Ball Valve

A 3-pcs stainless steel Ball Valve uses stainless steels as its material, and  it inherits the features of a ball valve, such as durability, because they have the same structure, meaning it has a spherical disc, which is the control part. The sphere has a hole through the middle. 3-pcs stainless steel Ball Valve  only needs 90 degree operation or a small rotation torque can be closed tightly. Fully equal chamber provides a straight-through flow channel with little resistance for the medium. People usually believe that the most suitable usage of three piece ball valve is opening and closing directly, however, the recent development has been designed it for flow control. It has its own unique advantages because of its structure, such as the switch without friction, seal easy to wear, hoist torque small. It reduces the actuator with the specifications. Accompanied by multi-turn electric actuators can be realized on the media regulation and tight cut.

Usually, stainless steel material can be divided into three kinds: ss304, ss316, 66316L, which is divided according to Cr / Ni ratio. 304 is a low carbon modification of 302 SST for restriction of carbide precipitation during welding. 304L is a lower carbon modification of 304 for further restriction of carbide precipitation during welding. Max carbon in 304 is 0.08 versus 0.15 in 302 and 0.03 in 304L.316 is more corrosion resistant than 302 and 304, with higher creep strength, primarily due to the higher Nickel content. 316L is again primarily used for welded construction. 316 has the same carbon content as 304 and 316L as 304L.316L can be used in place of 316 in all applications but the reverse is not true. 316L should be used for welded structures requiring high corrosion resistance. 316L is more expensive than 316 in most regions of the world.
