JB/T 2001.48-1999Water systems - Air gate valves for pump stations (PN 31.5 MPa) (English PDF)

JB/T 2001.48-1999 is the English-translated version of 水系统 泵站用气闸阀(PN=31.5MPa).

JB/T 2001.48-1999 is a recommended standard of the Chinese machinery industry dealing with the air gate valves used in pump stations. It fixes their types, dimensions and technical requirements for a nominal pressure of 31.5 MPa, the valve being the one that controls the high-pressure air line of a station driven by pumps and accumulators. The 20 MPa version of the same valve makes up a separate part of the series. This part quotes JB/T 2001.47-1999 and carries the J20 classification. It takes the place of JB 2051-1984. It was issued on 1 January 1999.
