    Default Part #s for double piloted check valve

    I have found that the grapple can be forced open with sufficient force. I attribute this to the expansion of the long run of hoses to the grapple cylinder. I am thinking about using a double piloted check valve at the cylinder to prevent the grapple being forced open.

    I would appreciate manufacturer's names and part number for me to study. I have looked at the Prince valve but the cylinder ports are out the side and plumbing would be easier if they were out the ends. Are there any others out there?

    No PNs but Sun and Vickers make them. No load checks on grapple control valve?
