Dual Cross-Over Direct Acting Relief Valve (1inch Ports)
large-port variant of the cross-over shock valve, rated for 1" BSPP connections and up to 160 l/min. It is sized for high-flow hydraulic motor and drive circuits where the smaller DI-180° sizes would create unacceptable back-pressure at operating flow.
The two high-pressure setting ranges (20–200 bar and 50–400 bar) align with heavy-duty mobile and industrial motor protection requirements.
