*1 For a metal seat, we can handle only 1/8" and 1/4" sizes. Since the valve dimensions change if a metal seat is selected, contact our sales representative for details.
*2 The branched flow type is to the right of the diagram.
*3 In cases where there are different types of fittings, please note them in the order of Port A, B, and C of the internal flow in the diagram to the right.
Example) In the case where A port = CVC female, B port = CVC female, C port = CVC male, the model will be "VFVFV."
