German BW Hydraulik valves, BW Hydraulik models, BW Hydraulik prices

BW Hydraulik valves are directional control valves with more than two flow patterns and more than two oil ports. They are valves that enable communication, cutoff, and reversal of hydraulic oil flow, as well as pressure unloading and sequential action control. These directional control valves operate via the relative motion between the spool and the valve body. There are two types: rotary valve and slide valve. They are classified into two-position, three-position, etc., based on the number of working positions where the spool stays within the valve body; and into two-way, three-way, four-way, and six-way, etc., based on the number of oil circuits connected to the valve body. Methods for operating spool movement include manual, mechanical, electric, hydraulic, and electro-hydraulic.
