Kana kumanikidzwa paV2 kwakwira pamusoro pesimba re spring bias, chigaro chekutarisa chinosundirwa kure ne piston uye kuyerera kunobvumirwa kubva paV2 kuenda kuC2. Kana kumanikidzwa kwemutoro paC2 kwakwira pamusoro pesimba re pressure, basa re direct operating, differential area, relief function rinoitwa uye kuyerera kunoderedzwa kubva paC2 kuenda kuV2. Ne speed ye pilot paV1-C1, pressure setting inoderedzwa zvichienderana ne ratio yakatarwa ye valvu, kusvika yavhurwa uye yabvumira kuyerera kubva paC2 kuenda kuV2. Spring chamber inodururwa kusvika paV2, uye chero back-pressure paV2 inowedzera ku pressure setting mumabasa ese.
