GKV80 Sectional Directional Control Valves

Features Valve body is made from grey cast iron (inlet module, work module, outlet module) Spring cap, mechanical detent cap and electrical or hydraulic pilot controlled module are made from cast aluminum or die-cast aluminum. Parallel circuit: each section feature a load check valve, optional inlet port with a overload valve or check valve. Overload protection valve for anti-cavitation. Series circuit is available. Optional control method: electric, hydraulic remote, manual and wire pulling. Available power beyond port. Can be modified to be a closed center. Optional mechanical positioning, with adjustable force. Inlet module can configure a direct acting or pilot relief valve and the valve position can be changed. Hydraulic lock valve is available on each port. Mechanical hydraulic lock is also available to adapt to the requirements from lifting mechanism of tractor and lifting machinery for locking heavy items. Different functions of spools are provided to control two-way cylinder, one-way cylinder, or for hydraulic motor. Valve spool with floating function is available. Valve features small operating force and good flow characteristics. Proportional control is achievable (without pressure compensation). Section numbers: 1-8. Specifications
