Applied Industrial Technologies offers an array of hydraulic valves and related accessories, including cartridge valves, directional control valves, flow/motion control valves, hydraulic ball valves, pressure control valves, proportional directional valves, and SystemStak valves. Some of the in-line/body ported directional control options are buildable sectional valves, log splitter valves, and Monoblock valves. Hydraulic ball valves are available in a variety of configurations, with connections types such as BSPP and Code-614 bolt flange, materials such as brass, steel, and stainless steel, and several installed options like one-way or two-way, with or without lock, or flat, non-offset handle. Meanwhile, the SystemStak valves are available for pressure control, flow control, and checks. In total, the company offers some 18,000 hydraulic valves and accessories.

HydraForce offers hydraulic cartridge valves and electro-hydraulic control systems. Solenoid on/off valves come in a variety of configurations (from 2-way up to 6-way, poppet-type or spool-type, etc.), as do the directional valves, which include guided check valves, load shuttle valves, and piloted 2-, 3-, and 4-way spool valves.

Sun Hydraulics has developed several standard valve packages, including a line mount, sandwich, and Solenoid operated assembly cross references, and is also capable of custom-engineering valve packages calls "valvepaks." The valvepaks are backed by Sun's screw-in hydraulic cartridge valves, and their manifolds are manufactured in either T-6061 aluminum (3,000 psi) or 65-45-12 ductile iron (5,000 psi); they can also accommodate up to 30+ individual cartridge valves. These screw-in cartridge valves are a trademark of the company; they are available in up to five sizes/capacities, and can handle flows up to 400 gallons per minute and pressures up to 5,000 psi.

Brand Hydraulics offers a variety of hydraulic valves, including 4-way directional control valves with a hydraulic kick out, mono-block directional control valves with an auto-cycle hydraulic kick out, and adjustable hydraulic relief valves.

Bucher has a wide array of hydraulic valves.Types include safety relief, flow preventing, directional spool, and direction seat hydraulic valves.

Cross Manufacturing produces several hydraulic valves. Relief valves come in Model RC (a dual relief, differential poppet style for cylinders or motors, that handles up to 3,000 psi and 30 GPM), Model RD (hydraulically dampened differential poppet-style, 3,000 psi, 30 GPM), and Model RV (pilot operated, up to 3,000 psi and 40 GPM). There are five models of directional control valves, including the Model SS (up to 3,000 psi and 9 GPM), Model AD (3,000 psi, 15 GPM), and Model BA (1 to 3 spool valve, up to 2,500 psi and 30 GPM). The company also manufactures six selector valves, which can support between 3,000 and 5,000 psi and 20 to 50 GPM.

Northman Fluid Power offers three main types of hydraulic valves. Its hydraulic Solenoid valves are available in sizes D03, D05, D07, D08, and D10; molded plug-in coil and housing, indicator lights, mounting bolts, and AC or DC coils come standard. The modular hydraulic control valves, for mounting between directional valves and subplates or manifols, offer presure and flow control. Lastly, the hydraulic pressure and flow control valves provide relief, sequence, counterbalance, and pressure reduction, and are either threaded or subplate mounted.
