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.

Grainger distributes a variety of hydraulic valves, such as relief, pressure contro and split flow valves. Hydraulic valve models include the Prince RD1850H, with a max flow 16 GPM and pressure range of 1,000 to 2,500 psi, and the Vickers CS-03-B50, with a max flow of 45 GPM and pressure range of 125 to 1,000.

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.

Vescor offers both ball valves and needle valves. The ball valves come medium/heavy duty, 3-way high pressure (up to 4,600 psi), and 3-way high pressure (up to 6,000 psi) with split flange. The Mini Line Series needle valve is appropriate for use with oil, water, and most chemicals in test bench and control panel environments, while the 2000 Series is ideal for applications that require fine metering and shut-off. Lastly, the Tru Micro TMF Series with Color Bands provides metered flow in one direction and free flow in reverse direction, with re-set repeatability within 1%.

Westfield Hydraulics develops, engineers, and produces many electro-mechanical devices and fluid power assemblies. Among their offerings are thrust reverser valves, steering valves, hydraulic Solenoid valves, multi-position hydraulic Solenoid valves, and check valves. The company can also manufacture customer-designed valves and related products.

Atos Electrohydraulics offers both proportional valves and cartridge valves. The proportional pressure valves are suited to support max flows as low as 4 L/min, and as high as 600. The proportional directional valves come standard direct operated, but also can include one or two position transducers. The proportional cartridges, meanwhile, are designed for compensation, relief, or reducing. Finally, there are six cartridge valve options that can provide pressure, flow, or directional control, or on-off active safety functionality.

Oilgear offers a full range of standard and special function valves, as well as custom-design flexibility. Sizes range from 0.25" to 38", while maximum pressure is 60,000 psi and flow, 26,420 GPM. A number of mounting options are available, as well: manifold, sub-plate, flange, and pipe.

FORCE America sells five valve models. The Add-A-Fold 2010, Add-A-Stack 4020, and Add-A-Stack 2512 valves are all integrated mult-function valves designed to electronically control both cylinders and motors, while the Add-a-Fold 4520 valve is meant to protect against corrosion. Finally, the SCE Spin-A-Veyer valve is a compact electro-proportional control valve designed for spreader applications.
