    Benefits

    • Circuit protection against pressure spikes (the valve intervenes automatically when pressure exceeds the set value)
    • Stable and precise pressure even with varying flow rates
    • No need for different valve bodies thanks to versions DA, DB, DP, DC and DD covering any protection layout
    • The Z2DB version with dual cartridge in the same plate allows two channels to be protected simultaneously with a single component, saving space in the stack
    • Reduced footprint (no additional fittings or pipework required)

    Application fields

    • Machine tools
    • Hydraulic presses
    • Fixed industrial systems with overpressure protection requirements
    • Environments requiring biodegradable or fire-resistant fluids
