1 product overview:

●ZLSL and ZLSV proportional multi way valves are used to control the movement direction and speed of hydraulic actuators (continuously and independently of the load). To achieve this, multiple actuators can work simultaneously and independently at different speeds and pressures until the total flow of all parts reaches the flow rate of the pump.

●This multi way valve is a combination of directional valves that can control multiple hydraulic actuators. It is a multifunctional integrated valve mainly composed of directional valves, one-way valves, safety valves, oil replenishment valves, diversion valves, and brake valves.

●ZLSL and ZLSV proportional multi way valves are composed of single piece valves.

●ZLSL type is suitable for quantitative pump systems.

●The ZLSV type is suitable for variable displacement pump systems, and both have three specifications.
