Four section control valve for main operations of mobile cranes


Purpose:
Control valve is intended for launch, shutdown and reverse of working fluid flow.

Four section hydraulic control valve is applied for regulation of mobile crane operations:
- lifting-lowering of arm;
- telescoping of arm;
- cargo winch drum rotation;
- platform rotation.

Design:
- type of regulation - mechanical (cable or pull rods);
- spool return to neutral position – spring loaded;
- safety relief valve with electric unload is  mounted in pressure line;
- possibility to mount safety relieve and check valves into working sections;
- possibility to mount the spool relay «ON - OFF» into the working sections.

Control valve 1RM203 series


Purpose:
Control valves 1RM203 series are intended for changing the direction or launch and shutdown of working fluid flow in hydraulic systems of machines and mechanisms.

Application:
Hydraulic volumetric drives of mobile and stationary systems of machines and mechanisms. 

Design:
The spool providing conventional circuits of flows distribution (14, 24, 34, 44, 54, 64, 64A, 74, 84 etc.) is located in the housing of control valve (own casting).
The spool is shifting into working positions under the influence of the handle and can be fixed at full shift positions.
Mounting plates for control valves can be ordered separately.
