(VS311-VS312-VS315)Functional description3Functional descriptionA valve basically consists of a housing (1), a control spool(2), a return spring (3) and a solenoid (5). It is designed to connect two inlet lines P1 – P2 (normally a set of hoses) and divert them to either the outlet ports (C1 – C4) with spool in position “0”, when the solenoid is de-energized, or to the outlet ports (C2 – C3) with spool in position “1”, when the solenoid is energized.With the coil de-energized, the return spring (3) pushes back the spool (2) and holds it in position “0”.The coil (5) is fastened to the tube by the ring nut (6).The manual override (6) allows to shift the spool (2) also in case of voltage shortage.An external drain, to be connected to tank, ensures shifting operations also at higher working pressure.Hydraulic / pneumatic pilot control for spool shifting is available upon request.Technical dataMaximum pressure with external drain (“E” type)bar (psi)310 (4500)Maximum pressure with internal drain (“I” type)bar (psi)250 (3625)Maximum pressure with internal drain and6F or 6G schemebar (psi)310 (4500)Maximum fl ow l/min (gpm)140 (36.98)Pilot pressure needed for hydraulic / pneumatic control bar (psi)max 200 (2900) - min 4 (58) with external drain.For versions with internal drain, the pilot pressure required shouldbe at least 11 times higher than inlet pressure (ratio 11:1).Hydraulic fl uidGeneral properties: it must have physical lubricating and chemical properties suitable for use in hydraulic systems such as, for example:Mineral oil based hydraulic fl uids HL (DIN 51524 part 1).
