Product Description

GKV35 series sectional valves are open circuit valves. Mainly used in mobile machines such as, agricultural machinery, construction machines, mining equipment, material handling equipment as well as maintenance machines. The valve series adapted modular design. The system designer can choose different modules to design a complex system. Main valve spool is designed to satisfy with the customer requirements, which provides excel_x005flent flow characteristics and very low flow force. With different inlet modules, it gives user the freedom for choosing different relief valve and different port locations. There are numbers of different work section modules to choose to satisfy the customer needs. Different end sections also provide the customer needs for return ports or power beyond functions.

Functions

A/B Port with overload valve on main section
A Port with overload valve on main section
B Port with overload valve on main section
A/B Port with check valve
End section with oil return port
End section without oil return port
End section with power beyond port
Provide other cartridge valve option

Features

Cast iron body (inlet section, main section and end section).
Spring cap, mechanical detent cap, as well as electric or hydraulic pilot controlled module body are made by
cast aluminum or die-cast aluminum.
Parallel circuit. Each section has its own load check valve, Each section has load relief option and relief style options.
Can be changed to series circuit.
