Summit Hydraulics Hydraulic Multiplier Kit with Couplers
The Summit Hydraulics hydraulic multiplier converts one circuit into two, letting a single remote control operate two circuits or functions from the cab lever. It’s designed for simple installation and portability between units. Suitable for systems handling up to 20 GPM and 3000 PSI, it suits mid-range hydraulic tasks on tractors or compact machines. Best for operators who want to expand capability without complex plumbing or new remotes. A potential limitation is the need to ensure your current system’s flow and pressure are compatible with the multiplier’s rated capacity.
Key Features
- Converts 1 circuit to 2 circuits with a single control point
- Suitable for up to 20 GPM and 3000 PSI
- Simple installation and transferability between units
Best For
- Tractors or machines needing an extra hydraulic function without a full valve retrofit
E-cowlboy SCV Splitter Valve 2 Circuit Kit
The E-cowlboy SCV Splitter Kit expands a single hydraulic circuit into two independent circuits. It’s designed to fit popular tractors (John Deere, Case, Kubota, Ford) with ISO systems and requires no welding or adapters—just plug into rear remotes. The kit supports open/closed/FPC system configurations and is rated up to 3000 PSI. Choose this if you want a plug-and-play enhancement for two new circuits on existing ISO-based hydraulics. A limitation to note is that installation accuracy depends on compatible remotes and valve profiles.
Key Features
- Plug-and-play expansion to two circuits
- Fits John Deere, Case, Kubota, Ford ISO systems
- 3500? 3000 PSI rating with CNC-machined steel build
Best For
- Farm equipment requiring two independent hydraulic circuits without custom fabrication
Fluidhaus Electric Solenoid Valve, 3 Position
The Fluidhaus 3-position directional control valve uses a universal solenoid design that can fit D03 (USA) or NG6 (international) manifolds. It’s built to reliably direct hydraulic flow for cylinders and motors, with a robust encapsulated coil for moisture and temperature resistance. The valve is suitable for OEM replacements or universal remotes. It’s best for systems needing dependable actuation in a compact footprint. A potential limitation is to confirm voltage and mounting pattern compatibility with your existing hardware.
Key Features
- 3-position solenoid valve for hydraulic direction control
- Encapsulated coils for protection and longevity
- IP65 rated for dust and water resistance
Best For
- Replacing worn valves or integrating a reliable universal control point
Summit Hydraulics Electric Double Acting Valve, 2 Spool
This 2-spool double-acting valve provides precise control for two independent hydraulic circuits. With a 12VDC power supply and a 15 GPM flow rating, it’s designed for open-center, two-station configurations. Best for adding an auxiliary function or replacing an existing valve when you need independent control of two double-acting cylinders. A limit is that the setup is suitable for open-center systems; if you operate a closed-center system, compatibility should be verified.
Key Features
- Two-spool, open-center configuration
- 15 GPM flow, 12V operation
- Controls double-acting cylinders
Best For
- Adding or upgrading a second independent function on an open-center system
Summit Hydraulics 4-Spool Electric Valve with Rocker
This 4-spool valve provides comprehensive control for multiple double-acting cylinders. It includes a rocker switch with an 8-foot total harness that allows flexible mounting and easy operator access. It’s best for contractors or farm operators needing precise control over several hydraulic functions from a single control point. A limitation is the longer wiring harness, which may require careful routing to avoid snag hazards in tight spaces.
Key Features
- Four spools for multiple circuits
- 12V operation with 15 GPM rating
- Rocker switch with extended harness
Best For
- Complex auxiliary setups requiring multiple controlled functions
Solarhome Hydraulic Control Valve Kit with Joystick
The Solarhome kit provides a two-spool hydraulic valve with a remote joystick, offering two independent circuits controlled from a joystick for convenient operation. The system supports a high nominal flow and is designed for flexible remote control. It’s best for operators who want ergonomic control at a distance from the valve bank, such as in dump or load operations. A caution: verify compatibility with your existing hydraulic components and remote joystick interface.
Key Features
- Two-spool valve with remote joystick
- Nominal flow around 21 GPM; adjustable relief
- High operating pressure and remote operation
Best For
- Remote operation scenarios needing two independent functions
Buying Guide: Key Considerations for Electric Over Hydraulic Valves
What’s the difference between electro-hydraulic and purely hydraulic valves?
Electro-hydraulic valves use electrical actuation to control hydraulic flow, offering faster speed, easier integration with electronic controls, and the ability to route multiple functions from a single control point. Purely hydraulic valves rely on mechanical or remote-operated levers and may require more manual wiring or a larger control surface.
How to choose the right valve kit for your tractor or machine
- Flow and pressure: Match the GPM and PSI ratings to your system’s capabilities (e.g., 15 GPM at 3000 PSI or similar).
- Spool configuration: Decide if you need 2-spool, 4-spool, or more for the number of cylinders you control.
- Control method: Remote joystick, rocker switch, or direct cab lever control—choose what fits your operation style.
Installation and compatibility considerations
- System compatibility: ISO or OEM remotes, open-center vs. closed-center configurations.
- Mounting and wiring: Ensure adequate space for mounting valves and routing hoses safely.
- Voltage and connectors: Confirm 12V compatibility and connector types (D03 or NG6 as examples).
Durability and environmental considerations
- Coil protection: Encapsulated coils or moisture-resistant designs extend life in rugged environments.
- Sealing and ratings: IP65 or equivalent protection helps against dust and water exposure.
Safety and maintenance
- Relief valves and overpressure protection must be correctly set to prevent component damage.
- Regular inspection of hoses, fittings, and electrical connections is recommended.
FAQ
- What is the benefit of adding a second circuit? — It enables independent control of additional hydraulic functions from a single system.
- Can I replace my current valve with an electric one? — Yes, if the mounting pattern, spool configuration, and electrical voltage match your system, a replacement can be straightforward.
- Do these kits require welding? — Most listed kits are designed for plug-and-play installation without welding, though some setups may require minor plumbing adjustments.
- Is a remote joystick more convenient than a cab lever? — A remote joystick provides ergonomic control in the field and can improve efficiency for certain tasks.
- What should I verify before buying? — Confirm flow, pressure, spool count, control method, mounting pattern, and compatibility with your tractor or machine’s ISO remote system.
- Are these valves suitable for commercial trailers? — They can be, provided the system’s pressure and flow specifications align with the valve ratings and installation complies with safety guidelines.
