The 562 Series is a four-way spool valve designed for double-acting process valves, while the 362 Series is a three-way valve made for single-acting process valve applications. Both valve lines are ...

DSSV dampers push their fluids through laser-etched openings in spool valves inside the damper that open and close as a sleeve slides up and down around them. Sleeve slides down, orifices open.

In one case the spool readily shifts while it "hangs up" in transition on the other. This illustrates that estimating flow forces in spool valves must account for other hydraulic-system components.

Why Spool Valves In Multimatic’s DSSV dampers, spool valves replace the traditional piston and shims. Each spool valve has a spring-loaded valve that opens and closes at a variable rate ...

The Canadian company Multimatic's True Active Spool Valve Dampers use a 48-volt motor to put force into the damper. It's a gamechanger.

The valve mounts at the machine's hydraulic cylinders and provides precise bidirectional metering, zero-leak load holding, as well as functions not possible with conventional spool valves.
