1500LB Forged Steel Weld Bonnet Gate Valve,A105N Body,DN50,Socket Weld End

1500LB Forged Steel Weld Bonnet Gate Valve of the handwheel transmits torque to the valve stem through the stem nut. the valve stem is forged and tempered with A182F6 (1Cr13) and has a hardness of HB220-250. in order to reduce the loss of power during the transmission process, the stem nut is made of high-nickel ductile iron A439GR.D2 or copper alloy (high-nickel ductile iron has certain self-lubricating properties), and the hardness is about HB50 smaller than the valve stem.

Forged steel gate valves are suitable for small diameter pipes with operating temperatures of -29-450 ° C (carbon steel) or -29-500 ° C (stainless steel). It is used to cut or connect the media in the pipe. Different materials can be used. In water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
