1product overview ：

The ZLSLF and ZLSVF proportional multi way valves are composed of single valves installed on a plate. The ZLSLF type is suitable for quantitative pump systems (pressure/regulating valves), while the ZLSVF type is suitable for variable displacement pump systems, and both have two specifications. ZLSLF and ZLSVF proportional multi way valves are used for stepless speed regulation of hydraulic actuators, with speed regulation independent of system load. Multiple execution elements can work simultaneously and independently. This type of valve is mainly used in hydraulic systems of walking machinery. Compared to the ZLSL/ZLSV type, its main advantage is that it simplifies valve maintenance and can be easily replaced.

ZLSLF and ZLSVF are mainly used in hydraulic systems of walking machinery (such as lifting machinery, etc.). By selecting different maximum flow rates for actuator A and B ports, as well as choosing to use various additional functions (such as function cutoff), the optimal matching of each control circuit can be ensured.

3 Available varieties：

3.1Oil inlet block (control panel)

There are two basic forms of connection blocks (oil inlet blocks):

1. Connection block with integrated three-way pressure compensator for quantitative pump system (open circuit) ZLSLF type

2. ZLSVF type connecting block used for variable displacement pump systems (closed circuits), constant pressure systems, or parallel supply of oil to one or more slide valve type directional valves installed for secondary separation

Ordering code for a single connection block (example): ZLSLFA1F/250-5-G24

Attention: Must have size specification -5 ZLSVFA2/300-5
