Frequently Asked Questions

What is the nominal pressure rating for the D342X-10/10Q model?

The nominal pressure (Mpa) rating for the D342X-10/10Q butterfly valve series is 1.0 MPa.

What are the water test pressure standards for this series?

The testing standard specifies a strength test pressure (water) of 1.5 MPa and a seal test pressure (water) of 1.1 MPa.

What media and operating temperatures are suitable for D342X-10/10Q?

This model is designed for water applications and operates efficiently at working temperatures up to ≤100°C.

What nominal diameter sizes are available in this series?

The D342X-10/10Q model accommodates a wide range of nominal diameters, ranging from small DN80 mm sizes up to large-scale industrial 4000 mm sizes.

How do I interpret the flange drilling specification (Z-φd)?

The Z-φd column indicates the number of bolt holes (Z) and the hole diameter (φd) in millimeters. For example, "8-φ19" represents 8 bolt holes with a diameter of 19 mm each.
