hydraulic control valve
The LBF series of flow ratio distribution load-sensing multiple valve is the company's latest patented product with optimized design which absorbs the world's cutting-edge load sensing technology integrated with the characteristics of hydraulic system of construction machinery at home and abroad. LBFTM (flow ratio distribution) is the company's registered trademark and its product series are checked for bench test and actual operation, comes up to the design requirements for performance indices, and is successfully used in various kinds of hydraulic system of construction machinery. The LBFTM product series feature flow ratio distribution (LBFTM) independent of load pressure, anti-interference, anti-saturation, precision and inching control, excellent ratio property, and high efficiency and energy saving, therefore, it is an ideal product for nationalizing and upgrading construction machinery and heavy-duty equipment.
LBFTM product series are widely used in cranes, digging machines, helical diggers, marine machinery and other mechanical devices, especially in multi-structured combination machinery.
Advantage
1.High precision of distribution (3-5%)
2.Good performance of anti-jamming (independent load contro for different actuators)
3.High conrtol accuracy (1mm)
4.High efficiency
5.Adapt to various systems and different control modes
6.Excellent ratio property
7.the single hydraullic pump can meet the pressure and flow requirements in multiple loops.
