Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Are butterfly valves and check valves fitted together?Butterfly valve is nothing positive and negative ah!
Hard seal butterfly valve in any case, the reverse loading will cause tight seal.
Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that
