In a neutral position (unpiloted), the IPD10-41 allows flow from ③ to ④, while the flow is blocked at ②. On remote pilot signal at ①, the valve shifts to open from ③ to ②, while blocking flow to ④. Since ④ is connected to the spring chamber, pressure on ④ will directly (1:1) affect the pilot pressure required, and must always be added to the bias spring value.
Consult Inno for applications where bi-directional flow is required when the valve is in the normal or spring-offset position.
