I am having trouble connecting a Gate Valve block to my hydraulic circuit. The hydraulic circuit uses a constant pressure source and passes flow through a 4-way directional valve to a motor (not pictured). I want to add a gate valve after the directional valve so that I can proportionally restrict flow.
The pipe is 19mm in diameter, however the constant signal that is being passed into the gate valve is 9 becuase I want to restrict the flow about 50%.
The pressure sensors before and after the gate valve indicate that there is no change in the flow. How do I fix this issue, so that the gate valve will proportionally restrict flow when I feed in different values?
