Both types are used with a single-acting cylinder. ● Connect the valve directly to the tank so that no back pressure is applied to T port. ■HV-1Maximum operating pressureMPaModelHV-170FV-1● Extremely small leakage. ● SMVT manual direction-control valves are mainly used with a hand pump for double-acting cylinders. ● The SMVHT can maintain the pressure even in neutral and during the switching transition period. The hold pressure is released by switching to the port on the opposite side. ● The HOV is a manual direction-control valve, and various models are available for selection according to the neutral system and maximum flow rate. ● All ports are open (P, T, A, and B ports are connected) during the switching transition period (except the SMVHT). ● A pressure of up to 70 MPa can be applied to C (T) port of a tandem center model. Be sure to connect DR port to the tank.■ SpecificationsModelHydraulic symbol nameSMVT-43Center bypassSMVHT-43Center bypassHOV-43Center bypassHOV-43HAll ports openHOV-43PP port blockedHOV-43CAll ports blockedHOV-43TTandem centerHOV-44Center bypassHOV-44HAll ports openHOV-44PP port blockedHOV-44CAll ports blockedHOV-44TTandem centerHOV-48Center bypassHOV-48HAll ports openHOV-48PP port blockedAll ports blockedHOV-48C* The approx. weight of the HOV-43H/P/C-F and HOV-44 H/P/C-F is 4.6 kg.* The size of T port of the HOV-44H/P/C, DR port of the HOV-44T, and C (T) port on the bottom of the valve is Rc3/8.
