Continental Hydraulics manufactures hydraulic proportional, modular stack, and directional control valves. Modular stack valves can handle temperatures up to 200°F, pressures up to 5000 PSI, and flows up to 60 GPM. These pumps feature zinc-plated external parts, reduced system space, 10 micron filtrations, and industry common cavities. Applications include farm equipment, oil fields, heavy construction equipment, off-highway equipment, marine, food processing, machine tools, etc.

Eaton Hydraulics provides a range of hydraulic valves, including direct operated Vickers inline, right angle, and manifold mounted check valves for one-way flow in hydraulic circuits, and flow control valves that cause variable pressure drops in fluid passages in order to reduce flow. They also have recently added Vickers KB Proportional Directional Valves, which are IP65 and 67 rated, and tolerate pressures up to 5,000 psi and flows up to 185 US GPM. Other valve choices include directional, flange, pressure control, proportional flow, and proportional pressure valves.

MICO manufactures hydaulic valves for automotive applications. The electrohydraulic brake valve, EBV-S12 Series, is a closed-center, full-power valve that modulates output pressures up to 2,900 psi. The in-line check valve is a non-adjustable valve that allows free flow of hydraulic system fluid in one direction, while maintaining residual fluid pressure from the opposing side.
