How to Order the VO40 Valve Assembly

A specification sheet is located in the back of this book, and is also available in an electronic Excel format on our web site. This form should be used to configure a valve assembly. The layout starts from the inlet cover on the left, work sections and mid-inlets in the middle and the outlet cover on the far right. Each field will require an entry, and the fields are represented with a position reference [ ] to help guide you to the option codes listed in the catalog pages 11 to 21.
