| Note: 1. Rating flow is the flow when import pressure of valve is 0.49MPa, pressure differential between two ends is 0.1 MPa, and valves are open. 2. Max. pressure drop is the pressure differential when the valve is closed. 3. Please note product model, capillary length, control range, hot medium(steam or hot oil) when you order the products. |
