I'm looking for a specific type of 3-way valve designed for a constant flow application. This valve should feature three ports: one for the supply inlet and two for the outlets. The operation of the valve is crucial, as it needs to manage the flow between the outlets. When outlet port 2 is closed and starts to open by 10%, outlet port 3 must simultaneously close by 10%. This process should continue smoothly until the valve is fully shifted, ensuring precise control over the flow. Additionally, the valve must be capable of operating at pressures of either 100 PSI or 145 PSI. It's important to note that the fluid involved in this application is fuel oil, so the materials used should be suitable for that medium. Please provide product options that meet these requirements, including any technical specifications and pricing details.
