D71X series butterfly valves are engineered primarily for water applications operating within a temperature range of -10°C to 80°C.
For the D71X-10/10Q model, the strength test pressure is 1.5 MPa and the seal test pressure is 1.1 MPa. The D71X-16/16Q model features higher pressure tolerances, with a strength test pressure of 2.4 MPa and a seal test pressure of 1.76 MPa.
The Q71X-10/16 series covers a broad range of nominal diameters, including DN40, DN50, DN65, DN80, DN100, DN125, DN150, and DN200.
The flange connection sizes vary by diameter: DN40 uses 4-φ21, sizes from DN50 to DN125 use 4-φ23, while larger sizes like DN150 and DN200 use 4-φ26.
These valve specifications support standard nominal operating pressure ratings ranging from 1.0 MPa to 1.6 MPa.
