Frequently Asked Questions (FAQ)

What media are compatible with Z545T and Z545W series valves?

The Z545T models are configured specifically for water applications, whereas the Z545W models are optimized for handling oils and hydrocarbon liquids, both operating safely up to 100°C.

What are the pressure testing standards for 1.0 MPa rated valves?

For 1.0 MPa (10 bar) nominal pressure units, shell strength testing using water is conducted at 1.5 MPa, while seat sealing tests are verified at 1.1 MPa.

What are the pressure test parameters for 0.6 MPa rated valves?

Valves rated for 0.6 MPa (6 bar) nominal pressure undergo shell strength testing with water at 0.9 MPa and seat sealing tests at 0.66 MPa.

What nominal diameter sizes are available for the Z545T/W-10 model?

The Z545T/W-10 model covers wide large-diameter requirements ranging from 900 mm to 1800 mm nominal diameters (DN 900 - DN 1800).

What is the maximum allowable operating temperature for these models?

All specified models including Z545T, Z545W, and Z445T/W are rated for operating environments with temperatures less than or equal to 100°C (≤100°C).

How do flange dimensions scale across larger nominal diameters?

Flange parameters like outer diameter (D), pitch circle diameter (D1), and bolt hole configurations (Z-0d) scale proportionally with nominal size, accommodating heavy-duty industrial pipe connections up to DN 1800.
