Q1: What media can the Z41W series gate valves handle?
The Z41W series stainless steel gate valves are suitable for handling water, steam, oil, and nitric acid corrosive liquids.
Q2: What is the maximum operating temperature for Z41W gate valves?
The maximum applicable temperature for Z41W-16P/25P models is ≤ 150°C, while the higher-pressure Z41W-40P model can withstand temperatures up to ≤ 425°C.
Q3: What are the nominal pressure ratings available for these models?
The series offers three standard nominal pressure ratings: 1.6 MPa (Z41W-16P), 2.5 MPa (Z41W-25P), and 4.0 MPa (Z41W-40P).
Q4: How are the water strength and sealing test pressures determined?
For Z41W-16P/25P, the strength test pressure ranges from 2.3 to 2.7 MPa, and the seal test pressure is 1.7 to 2.7 MPa. For Z41W-40P, the strength test pressure is 6.15 MPa and the seal test pressure is 4.51 MPa.
Q5: What size options are available for the Z41W valve series?
Nominal diameters (DN) range from 40mm up to 400mm for 16P and 25P models, and from 50mm to 200mm for 40P models.
