Frequently Asked Questions (FAQ)
What are the primary applications and suitable media for Z45X series gate valves?
The Z45X series gate valves are specifically engineered for water media systems operating within a working temperature range of 1°C to 80°C.
What pressure ratings are available for the Z45X gate valve models?
The series offers three nominal pressure ratings: Z45X-10Q at 1.0 MPa (10 bar), Z45X-16Q at 1.6 MPa (16 bar), and Z45X-25Q at 2.5 MPa (25 bar).
How are the strength and seal testing pressures determined?
Each valve undergoes rigorous water testing. For example, model Z45X-16Q is strength-tested at 2.4 MPa and seal-tested at 1.76 MPa to ensure reliable leak-free operation.
What nominal size range is covered in the Z45X series dimensional chart?
The Z45X-10Q/16Q models cover sizes from 50mm to 300mm, while the higher-pressure Z45X-25Q model extends from 40mm to 300mm nominal diameter.
What are the main structural differences between Z45X-10Q/16Q and Z45X-25Q?
Z45X-25Q is built to withstand higher nominal pressures (2.5 MPa) and features larger overall flange dimensions (D, D1) and hole counts/diameters (Z-φd) compared to 10Q/16Q configurations.
