Frequently Asked Questions

What is the difference between Q41F-16P and Q41F-25P ball valves?

The main difference lies in their nominal pressure rating and temperature tolerance. The Q41F-16P model operates at a nominal pressure of 1.6 MPa with a max temperature of ≤150°C, whereas the Q41F-25P model supports higher pressures up to 2.5 MPa and higher operating temperatures up to ≤425°C.

What media are these ball valves suitable for?

Both models are versatile and designed to handle water, steam, oil, as well as corrosive fluids such as nitric acid mixtures.

What are the strength and seal water testing pressures for Q41F-16P?

For the Q41F-16P ball valve, the water strength test pressure is set at 2.4 MPa, while the water seal test pressure is set at 1.8 MPa to ensure zero leakage and structural integrity.

What are the available size ranges for these valve models?

These models are available in nominal diameters (DN) ranging from 15mm (DN15) up to 200mm (DN200) to fit a wide range of industrial pipeline configurations.

How do bolt hole specifications (Z-φd) change across different sizes?

Bolt hole specifications scale according to valve size. For example, smaller diameters such as DN15 to DN65 typically feature 4 bolt holes (4-φ14 or 4-φ18), medium sizes use 8 holes (8-φ18 to 8-φ26), and larger sizes like DN200 use 12 holes (12-φ23 or 12-φ26).
