Basic module

PVBZ-HS (Hitch Single-acting)

The PVG 32 valve was originally launched on the
market in 1988 with a range of high performance
electrical actuators. In the late nineties, the program
was extended to also include new features such as
low leak ports, special inlet sections and special
electrohydraulic actuator options.

The special PVBZ-HS load and pressure compensated
module was developed for applications, which need a
valve slice for standard single acting cylinders.
Application examples are:

•

Rear-Hitch on tractors

•

Headers on combines and harvesters

The new PVBZ-HS basic module can be mixed with
basic modules PVB/PVBZ (with additional tank line
TO) and offers the following features.

Features

•

Low leakage work port

•

Special 3/3 spools

•

Separated tankport

•

Integrated PVLP 63 shock/anti­cavitation valve
