Duplomatic MCD4-SP/51 direct-acting pressure relief valve, modular NG6 (CETOP 3), on line P relieving to T, up to 140 bar.
Direct-acting relief valve in modular version, to fit as a sandwich on an NG6 (CETOP 3, ISO 4401-03) subplate, without pipes. The SP version limits the pressure on line P and relieves to T; the digit 4 gives the setting range up to 140 bar. Besides limiting circuit pressure, Duplomatic recommends it for cutting the peaks that appear when actuators move.
