    HOV SERJE jikkontrobilanċjaw valvi GĦALL-PUBBLIKU CENTER

    Deskrizzjoni fil-qosor:

    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.

    Meta l-pressjoni fuq V2 jgħola l-pressjoni preġudizzju rebbiegħa, is-sedil verifika hu imbuttata bogħod mill-pistun u l-fluss huwa permess minn V2 sa C2. Meta l-pressjoni tagħbija C2 jgħola l-iffissar pressjoni, il diretta operati, żona differenzjali, il-funzjoni eżenzjoni huwa attivat u l-fluss huwa meħlus minn C2 sa pressjoni pilota V2.With fil V1-C1, l-iffissar pressjoni mnaqqsa fi proporzjon mal-proporzjon iddikjarat tal-valv, sakemm ftuħ u tippermetti fluss minn C2 sa V2. Il-kamra tar-rebbiegħa huwa jintremiex fi V2, u kwalunkwe back-pressjoni fil V2 huwa addittiv għall-istabbiliment pressjoni fil-funzjonijiet kollha.
