Flows is 80 l/min (21 USgpm), 6* Design
P, A & B Pressures is 350 bar (5000 psi), T Pressures is 210 bar (3000 psi)
Tank line design is special with high rating.Tank line can withstand pressures up to 210 bar (3000 psi). DG4V3-60 is ideal replacement for high tank line pressure.
Due to new coil design,with characteristics of high thermal shock and impact resistance. Frame around coil ensures high strength and allows frame to expand/contract without adding stress.
With surge suppressor/diodes,can protect PLCs or circuit boards from back electro-magnetic force (EMF).
High performance features including minimal pressure drop, scratch-proof override sealing, high reliability, multiple electrical connections and ease of servicing.
Functions of DG4V3 vickers hydraulic valves are as following:
With spring return= without any sign
Without spring return =O
Without spring return with detent =OF

Pressure hydraulic direction control DG4V3-60 to control the hydraulic system pressure, therefore the selection should be based on the working state of the hydraulic system, the pressure on the requirements and DG4V3-60 hydraulic direction control valve in the system to the function. For example, in the quantitative pump throttle speed control system, the speed of the implementation of components controlled by the throttle hydraulic direction control valve; in order to maintain the working pressure of the pump is basically constant, should use the DG4V3 vickers overflow hydraulic direction control valve to carry out the regulator overflow; in order to prevent the system overload, the pump can be used in parallel with an overflow valve, for the protection of the pump and the whole system; if there is a decompression circuit in the system, the DG4V3 vickers pressure relief valve must be used to reduce the high pressure circuit to low pressure; if the system uses the pressure to control the action sequence of the components, should use the sequence hydraulic direction control DG4V3-60, the pressure value of the sequence valve is set to the required pressure, thereby controlling the action sequence of the parts, and also can use the pressure relay to convert the liquid pressure to the electrical signal, to control the action sequence of the various parts; if you are required to perform the component stably, the back pressure valve should be set up in the loop to form a certain resistance to the oil, which can greatly improve the stability of the execution element. Overflow valve, sequence valve, check valve and throttle valve can be used for DG4V3-60 back pressure hydraulic direction control valve.
