❓ Frequently Asked Questions (FAQ)

Q: What are the primary working media for Z944W-10 and Z944T-10 valves?

A: Model Z944W-10 is mainly suitable for oil media, whereas model Z944T-10 is suitable for water and low-pressure steam (≤1.0 MPa).

Q: What is the maximum applicable temperature range for these valve models?

A: The Z944W-10 model operates between -10°C and 100°C. The Z944T-10 model withstands higher temperatures, ranging from -10°C up to 200°C.

Q: What are the pressure testing standards for the Z944 series?

A: Both models have a nominal pressure rating of 1.0 MPa. The water strength test pressure is set at 1.5 MPa, while the water seal test pressure is 1.1 MPa.

Q: What nominal diameter (DN) size options are available for Z944T/W-10 valves?

A: The available nominal diameters range from 50mm (DN50) up to 400mm (DN400), covering standard industrial pipe sizes including 50, 65, 80, 100, 125, 150, 200, 250, 300, 350, and 400mm.

Q: Why are dimensions H, L1, L2, and Do listed as reference dimensions?

A: These parameters directly relate to the mounting configuration and specific electrical actuator interface, which may vary depending on the chosen electrical installation plant equipment.
