    Hov YOKUFUNDA nokulingana izivingco FOR iZiko

    Inkcazo elifutshane:

    When pressure at V2 rises above the spring bias pressure, the check seat is pushed away from the piston and flow is allowed from V2 to C2. When load pressure at C2 rises above the pressure setting, the direct operated, differential area, relief function is activated and flow is relieved from C2 to V2. With pilot pressure at V1-C1, the pressure setting is reduced in proportion to the stated ratio of the valve, until opening and allowing flow from C2 to V2. The spring chamber is drained to V2,and any back-pressure at V2 is additive to the pressure setting in all functions.

    Xa uxinzelelo kwi V2 liphuma ngaphezu emthonjeni xi bias, isihlalo itshekhi utyhalelwa kude ukusuka piston kunye budget avumela V2 ukuya C2. Xa uxinzelelo umthwalo kwi-C2 liphuma ngaphezu isicwangciso xinzelelo, xa ngqo utyando, indawo umahluko, umsebenzi isiqabu isebenza flow kuthatyathwa ukusuka C2 ukuya V2.With xi pilot kwi V1-C1, ucwangciso xi zancitshiswa ngokomlinganiselo ratio elixeliweyo ka vana, kude ukuvulwa flow ukuvumela ukusuka C2 ukuya V2. Eli gumbi spring .Kanye ku V2, yaye nayiphi na umva-uxinzelelo kwi v2 additive ukuya uxinzelelo isicwangciso kuyo yonke imisebenzi.
