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.

Technical parameters:

Parameter	Value
Nominal flow of working fluid, l/min	150
Max. flow of working fluid, l/min	170
Max. operating pressure, MPa	30
Max. pressure in drain section, MPa	2
Max. leakage from operating channels to drain line, cc/min	5
Working fluid temperature range, ⁰С	from -20 up to +80
Nominal filtration fineness, mkm	25
Weight (without working fluid), kg	30

Control valve 1PM203 series

Purpose:

Control valves 1PM203 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.

Technical parameters:

Parameter	Value
Pressure in lines «Р», «А», «В», «Т», MPa - nominal - maximum	32 35
Max. pressure in line «У», MPa	0.5
Internal leak proofness (leakage at 30 MPa and viscosity З6⁺⁴ cSt.) cc/min, not more than	300
Flow, l/min	450
Regulation power, N	53
Weight, kg, ± 5 %	14
