Dual Cross-Over Direct Acting Relief Valve (180° Ports)
Dual cross-over relief function in a 180° (in-line) port configuration, with work ports and cylinder ports on opposing faces of the manifold body. This layout is widely used for overload and shock protection on hydraulic orbital and piston motors across the 1/4" to 3/4" BSPP port range.
Four port sizes are available, each with a different max flow rating.
