Z44T series valves are specifically designed for water and steam applications (up to 1.0 MPa), whereas Z44W series valves are tailored for handling oils and related liquid media.
Z44T models can withstand operating temperatures up to ≤200°C, making them suitable for steam applications. Z44W models operate at maximum temperatures of ≤100°C.
For 1.0 MPa nominal pressure models (Z44T-10, Z44W-10), water strength test pressure is 1.5 MPa and seal test pressure is 1.0 MPa. For 1.6 MPa models (Z44T-16Q, Z44W-16Q), strength test pressure reaches 2.4 MPa with a seal test pressure of 1.76 MPa.
The Z44T/W-10 series offers nominal diameters ranging from 40mm up to 400mm, while the Z44T/W-16Q series covers nominal diameters from 40mm up to 300mm.
While external dimensions (like face-to-face length L and height H) are identical for equivalent diameters, high-pressure 16Q models feature specific bolt hole configurations (Z-φd) and flange sizes (D, D1) designed for 1.6 MPa pressure applications.
