Small Volume Control Valve

INTRODUCE OF GDV25

GRH Monoblock Valves are open center valves. Mainly used in mobile machinery such as, agricultural machinery, construction machinery, mining equipment, material handling equipment as well as maintenance machines. All valve series are adapted to modular design. The system designer can choose different modules to design a complex system. Main valve spool is designed to satisfy with the customer's requirements, which provide excellent flow characteristics and very low flow force. It provides different inlet port and return port locations, as well ae power beyond functions. GRH Monoblock Valve have  six series, each series has different assemblies. Some series have one spool, two spool, three spool assemblies. Some series have up to six spool assemblies. For detail information please refer to each's technical literature.

GDV25 series Mono-block valve provides the following features:

      ●Cast iron body.

      ●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. Inlet passage has a load check valve.

      ●Provides manual control and wire pulling control modules.

      ●Provides power beyond options.

      ●Provides mechanical detent.

      ●Provides different spool functions to satisfy with the needs for customers to control double and single cylinders, as well as to control Hydraulic Motors.

      ●Provides excellent flow characteristics and small operating force.
