Lifting-lowering valves are a combination of directional valves and metering valves.

The valve block type HSV provides the function of a 2/2-way directional seated valve with electrical actuation for lowering the load. Adjustable throttle valves or flow control valves independent of the load control the lowering speed. An integrated pressure-limiting valve limits the permissible load.

The lifting/lowering valve type HSV is used to control lifting equipment with single-acting cylinders.

This valve combination type HSV is preferably used for controlling lifting equipment with one or two single acting hydraulic cylinders. The valve consists of:

Solenoid actuated 2/2-way directional seated valve for lowering the lifted loadAdjustable throttle valve (optional) for limiting the drop rateThe 2-way flow control valve, available as option for valves type HSV 23-R6, ensure a largely load independent drop ratePressure limiting valve for the limitation of the permissible load (max. operation pressure). Factory set to 220 bar, adjustable up to 400 bar.Check valve prevents load pressure from acting on the switched off pump, when the load is lifted and prevents e.g. reverse rotation of the pump. The location of the check valve in relation to the pressure limiting valve depends on the application. Version R2 and R4 (S2 and S4) prevents uncontrolled lowering of the load in case the pressure limiting valve is floating (load pressure in the range of the set pressure).
