Product Description

Load Sensitive Flow Sharing Control Valve (LUDV Series)

1. The international advanced LUDV system can realize proportional flow distribution to all actuating mechanisms. Besides, the flow is not influenced by load. 

2. The neutral-position low pressure unloading mode can be suitable for a variable capacity system of which the neutral position cannot reach zero (also applicable to a fixed capacity pump system). 

3. Plate overlying can be adopted to combine a multiway proportional flow valve group according to the actual demand of customers. 

4. The circular arc groove orifice of valve rod can make flow more accurate and action more stable so as to cater for different working conditions. 

5. The electro-hydraulic proportional valve adopts an imported electromagnetic proportional reducing valve to achieve small hysteresis and high repetition precision and cater for installation with all kinds of precisions. 


Applications:

Applications and Features:
Mainly used in 100 ~ 320T Crawler crane fixed or variable pump system, and related similar symbol application in agricultural machinery, road and bridge machinery, sanitation machinery, mining machinery and etc.
The multi-way valve is a load-sensitive multi-way valve, and the flow rate is independent of the load. The valve is section structure, which can be expanded according to the needs, max section is 7 working sections; the valve is integrated with an oil return back pressure valve, which adopts a parallel circuit. That can effectively protect the radiator; the flow can be adjusted through the valve spool stroke, and each working section has a pressure compensation function; the working port can be set with a secondary pressure relief valve according to the needs; the control forms include hydraulic control, electro-hydraulic control; Integrated independent single and double pump switching function.
