The hydraulic control valves contained in this section include hydraulic directional spool valves that are solenoid operated as well as manual and pilot operated.
These hydraulic spool valves operate at up to 5000 psi and can flow up to 290gpm, depending on the size selected. A full range of mounting patterns is available, including ISO-3, ISO-5, ISO-7, ISO-8 and ISO-10. These hydraulic spool valves come with a full choice of spool configurations to accommodate any flow path or circuit condition required. The solenoid operated hydraulic directional valve can be configured as a 3-way or 4-way, 2-position single or double solenoid, or a 3-position 4-way double solenoid valve. For hydraulic manual control valves, you can choose from lever, knob or cam operated. Pilot operated hydraulic directional valves can be either hydraulically or pneumatically pilot actuated.
Wet-pin AC or DC voltage solenoids with detachable coil can be changed without having to open the pressure-tight chamber.
Most of these hydraulic directional valves have UL or CSA approval. Options include slow shift spools that eliminate hydraulic shock, explosion proof solenoid coils, a choice between individual solenoid DIN connectors, or a central cable entry junction box cover.
For leak free control applications, a single solenoid operated hydraulic directional poppet valve is available in ISO-3 (6100 psi) & ISO-5 (5100 psi) mounting patterns. These solenoid operated poppet valves are available as 2-way, 3-way, or 4-way directional control valves.
CMA/Flodyne/Hydradyne has a very large inventory of hydraulic directional control valves, which is backed up by Rexroth’s GoTo program. The GoTo program at Rexroth has identified the most popular hydraulic control valves and has inventory on hundreds of sizes and spool configurations for guaranteed shipment within 1 to 3 days. CMA/Flodyne/Hydradyne displays all the GoTo items in the clickable delivery field on our website.
All of the above hydraulic directional control valves are manufactured by Rexroth, the world leader in hydraulic pumps and valves. Rexroth has multiple manufacturing plants and warehouses in the United States.
