Choke valve casting is no difference between the shape of the choke valve and the stop valve, except that the shapes of the opening and closing parts are different. The opening and closing pieces are mostly conical streamline, so that it can change the channel cross-sectional area to achieve regulation of flow and pressure. Choke valve is used to reduce the medium pressure in case of large pressure drop. In the process of choke valve casting, there are many details to be aware of.
The performance requirements of choke valve:
1.Flow adjustment range
2.Small amount of internal leakage, if the leakage of oil port, the external leakage should be small
3.Adjusting torque is small, which has sensitive action
We wuxi Lingtong casting founded in 2003, with main sand casting products of sodium silicate sand, silica sand. In 2014, our factory moved to industrial park of Mashan in Wuxi Binhui District, in addition, we added 1.5 tons and 2 tons of medium frequency electric furnace, as well as sand mixer and phenolic resin regeneration system, and we have large-scale production of stainless steel sand casting, which mainly product the Stainless steel choke valve body investment casting, carbon steel and duplex stainless steel casting.http://www.pump-casting.com
