Sauer-Danfoss 157B4033 PVEH32 (s4) Proportional Valve

The Sauer-Danfoss 157B4033 PVEH32 (S4) is a DIN‑connected passive electrical actuator for PVG32 electrohydraulic proportional valve banks. This 1x4 DIN variant accepts a DC control signal within the 11–32 V range and interfaces with standard Danfoss control electronics via a four‑pin AMP/DIN connector, enabling proportional actuation of the PVG32 spool without onboard drive electronics. As a passive actuator, it relies on the valve’s drive electronics to translate the electrical signal into hydraulic motion, making it compatible with PVG32 and related PVG32‑family valve assemblies used in mobile machinery and industrial automation. The PVEH32 family is designed specifically for Sauer Danfoss PVG32 proportional valves, offering a compact form factor suitable for valve banks and modular valve blocks. Typical applications include hydraulic systems requiring precise, repeatable valve actuation and straightforward integration with common industrial controllers. The 157B4033 designation identifies the DIN‑based passive actuator variant within the PVEH32 line, supporting standard PVG32 valve stacks and retrofit configurations where a DIN 1x4 connection is specified.
