PREFILL AND EXHAUST VALVEPV <strong>100</strong> TO PV <strong>200</strong>ENGINEERINGRef. No. P04906Release 08/<strong>200</strong>61DescriptionSeat type construction.Allows free flow from it's port A <strong>to</strong> port B.Flow from port B <strong>to</strong> port A can be had by applying pilot pressure<strong>to</strong> it's port X.The decompression feature enables the <strong>valve</strong> <strong>to</strong> open in twostages progressively, allowing smooth <strong>and</strong> rapid <strong>exhaust</strong> <strong>of</strong> thecompressed oil.Opening <strong>and</strong> closing time <strong>of</strong> the <strong>valve</strong> can be influenced byproviding Throttle - Check Valves in the X port line.Flanged port A <strong>of</strong> the <strong>valve</strong> housing can be rotated aroundvertical axis through 360°.SectionXABHydraulic symbolXAB<strong>Polyhydron</strong> Pvt.
