Introduce of GKV35
GKV35 series sectional valves are open center valves, mainly used in mobile machines ,such as, agricultural machinery, construction machines, material handing equipment as well as maintenance machines, the valves series adapted modular design, the system designer can choose different modules to design a complex system, The range of valves includes some of which are for specific applications while others can be used for a wide variety of applications. A range of control options is available, from manual, to pilot hydraulic, to pneumatic control, to electro hydraulic control. Depending on model, features include: Sectional or monoblock construction, flow rating to 450 litres/min, multiple spool options, manual / hydraulic / electro-hydraulic / pneumatic control options, tandem circuit, multiple inlets.
GKV 35 series sectional valves provide the following functions:
● A/B port with overload valves on main section.
● A port with overload valve on main section.
● B port with overload valve on main section.
● End section with oil return port.
● End section without oil return port.
● End section with power beyond port.
● Provide other cartridge valve option .
GKV35 Series sectional valve provides the following features:
● Cast iron body (inlet section, main section and end section).
● Spring cap, mechanical detent cap, as well as electoral or hydraulic pilot controlled module body are made by cast aluminum or die cast aluminum.
● Parallel circuit, each section have its own load Check Valve,each section has load option relief option and relief style options.
● Can be changed to series circuit.
● Provides dump valve options for each center valve.
● Provides different drive modules (Hydraulic remote, manually control, wire driving).
● Provides power beyond port.
● Can be modified to be a closed center valve.
● Provides mechanical detent.
● Provides options for mechanically actuated P.O check valves to satified with the needs for tractors and mobile cranes.
● Provides different spool fuction to be used for controlling double acting, single acting cylinders, hydraulic motors.
● Provides floating fuction for spools.
● Provides excellent flow characteristics small operating force.
● Can be assembled with 1-8 main sections.

Basic Operation Principle
GKV35 series sectional valve is an open centered 3-position 4-way valve. When spool is in its neutral position, the flow from pump passes through the neutral passage to tank, with small pressure drops. When one of the spool is moved to 1 or 2 position, the neutral passage is blocked. The flow from pump can only pass the parallel passage to load check valve. Then, passes through the bridge and spool opening to work port A or B.
