3/2 Directional Valve
Metric cartridge – 250 bar
WKH05330
Spool Type - Hydraulically Operated
15 l/min
250 bar
The WKH05330 is a hydraulically
operated 3/2 directional valve which is
normally closed at the pump
connection 1. There is free flow through
the valve from port 2 (consumer) to port
3 (tank) below the set pressure.
During hydraulic operation, i.e. an
increase in pressure at port 1 against
the spring force, the valve opens from
port 1 to port 2. The tank connection 3 is
then closed.
feratures
Excellent stability over the whole flow range
Exposed surfaces zinc-plated and corrosion-proof
Minimal wear and long service life due to hardened and ground valve
components.
