Rugged, reliable electro-hydraulics
From simple switching valves to sophisticated closed-loop control, Sun's line of E-H products powers your most demanding applications
Sun has applied more than 50 years of valve design experience to its rapidly expanding line of electro-hydraulic products. We have studied the future of fluid power, benchmarked the competition on performance and price, and applied what we learned to develop some of the most reliable, hard-working solutions in the market today.
We build your solutions from the ground up, starting with a wide range of pressure control, flow control, directional and proportional valves with pilot-flow, full-flow and high-capacity versions available. We drive those electro-hydraulic valves with more than 100 different high-power, low-power and explosion-proof coils, providing precise control over millions of machine cycles.
And then we put you in charge, combining the XMD valve driver with our CANpoint Configuration Software to make implementation of your next solution simpler, more powerful and a lot smarter. Choose from open- and closed-loop configurations, with PID closed-loop pressure, position and speed control, variable-speed fan drive control and cylinder, pump and motor control. And we can help get you started with the new "Electro-Hydraulic Solutions" guide, including several circuit examples to point you in the right direction.
It all starts with the valves, right?
Sun offers more than 80 base model electro-hydraulic valves and hundreds of configuration options to give you the flexibility you need to configure the perfect solution for your application. Models include pressure and flow control; directional 2-, 3-, 4- and 6-way control; and a range of electro-proportional valves.
Choose the DTAF 2-way directional blocking poppet valve – a small, powerful workhorse with extremely low leakage that delivers more than 10 million operational cycles and can be used to pilot larger Sun valves for higher flow rates in mobile applications.
Or consider the patent-pending RVC* family of two-stage, fully adjustable, ventable and blockable reliefs that reduce circuit complexity by combining two functions in one valve and provide convenient field-adjustable relief settings. They offer precise, dependable pressure regulation with flow rates up to 25 gpm (100 L/min). Take a look at some great circuit examples in the RVC* family data sheet.
More recently, we introduced the space-saving, pressure-compensated FREP flow control, combining an electro-proportional orifice and pressure compensator – ideal for situations where you need to maintain constant actuator speed regardless of the load on the actuator. This innovative design provides excellent variable flow control when using a fixed-displacement pump.
And remember, with Sun valves, you always get high-quality, high-reliability products that meet your needs and exceed your expectations.
Every solenoid-operated valve needs a coil. And Sun offers a full range of coil options to support your system requirements. Models are available in low- and high-power versions with options for 12-, 14-, 24- and 28-Vdc and for 115- and 230 Vac. Connector options include DIN, Deutsch, AMP Junior, Metripack and twin leads.
And for hazardous locations, Sun offers explosion-proof coils that are ATEX, IECEx and CSA certified, with 90° and 180° connector options and in Vdc and Vac versions.
We have the coils to drive your application in any direction. See the full range of Sun coils on our website.
And Sun makes it easy to control it all with the XMD electro-hydraulic driver. The XMD gives you the power and flexibility you need for demanding applications. Available in single- and dual-output versions, it's compact, incredibly rugged and can be configured quickly and easily using a smartphone and Sun’s XMD Mobile app or on a PC using Sun's new CANpoint XMD Configuration Software.
The XMD driver is CAN configurable and designed for extreme conditions – perfect for demanding mobile environments. It's powerful, affordable, dependable and flexible.
Also, you can buy the Bluetooth XMD valve driver with the valve and coil of your choice, and we will factory tune the XMD, coil and valve to optimize valve performance. Learn more about our factory-tuned option here.
In addition to the discrete XMD driver, Sun offers a line of configurable IR embedded amplifiers that includes proportional and switching coil/controller models in 12- and 24-Vdc versions with either current or voltage command.
CANpoint Configuration Software is what brings it all together. It taps into the full capabilities of the XMD driver, providing quick, easy configuration over CAN bus using a computer. It allows XMD-02 users to implement open-loop, closed-loop (PID) and hydraulic fan drive control using pre-programmed modes for our dual-output driver.
CANpoint is a free software configuration program for the XMD mobile drivers that simplifies advanced hydraulic control using a clear, simple software interface that allows for point-and-click output shaping with excellent resolution and predictable results. And it requires no programming to take you from connecting to configuring to completing your application setup. Download the CANpoint software here.
Sun makes it easy to build your own electro-hydraulic solutions using our QuickDesign browser-based schematic tool. Take your idea from product specification to design using drag-and-drop, point-and-click tools. Once you’re satisfied with your circuit, submit it and get a finished package design in as little as ten minutes.
If you don't have your own resources, we support a global network of trained, authorized Sun Distributors that can assist you at any point in your development. That expertise can save you time and money and ensure that your solution is optimized to your application and takes full advantage of Sun's product capabilities.
