The name you know, the quality you trust

Offering solutions which leverage high performance and unmatched quality is a tireless feat Sun Hydraulics has embarked upon for over fifty years. Our dedication to deliver optimized solutions for a broad range of diverse markets has been exemplified from the genesis of the counterbalance valve which serves as a foreshadow of products to come, to newer products launched within the past year. Read on to learn more about Sun’s newest solutions and how they can enhance your applications.

Searching for energy savings? We’ve got your solution

The ecoline™ program is a collective set of energy-efficient solutions, created to permit users to easily locate products that have been proven to reduce energy consumption and increase savings. Featured in this energy-efficient product lineup is the high efficiency check valve ENERGEN™. This solution allows free flow from inlet to outlet and blocks flow in the opposite direction. Composed of an integrated generator that converts power losses into useful energy, ENERGEN™ delivers a robust approach to energy harvesting and check valve functionality.

Quick and easy solutions call for QuickDesign™

Sun’s QuickDesign™ has recently been updated to allow users the ability to configure Taimi cartridge swivel fittings into custom integrated packages creating new, reliable hydraulic capabilities. Additionally, users can now configure custom integrated packages with Faster Quick Release Couplings in QuickDesign™ too.

QuickDesign™ is a free, browser-based integrated package design program geared to facilitate the user’s design process. It features SmartConnect, a schematic tool which allows users to drag-and-drop product specifications and retrieve a completed design in as little as ten minutes.

Standard cavity solutions, powered by Sun

In 2022, Sun Common cartridge cavity valves joined the broad range of existing Sun valves. The zinc plated manual hydraulic hand pump, HPUA, is newly featured in the Sun Common line up.

More valve offerings included in the Sun Common Cavity family include the 4-way, 3-position electro-proportional FNUC and the 4-way, 3-position solenoid operated, DNUC and DNTC. The Sun Common cartridge family offers all your industry standard cavities, limitlessly powered with the quality of Sun Hydraulics.

Electro-Hydraulics designed for reliability and engineered to last

Electro-hydraulics solutions offered by Sun include a range of optimized valves, coils, drivers, and free configuration software with predictable results. Sun’s FREP is a FLeX Series 3-way, direct-acting, electro-proportional, bypass/restrictive, priority flow control valve that is well suited for situations where users need to maintain constant actuator speed regardless of the load on the actuator. 

Sun’s solutions for demanding applications

Sun's priority flow control solutions are all you need to have a wide range of durable and efficient options for your applications.

Whether you choose a standard priority flow control, a solenoid operated load relief, a fan drive solution, or a proportional, remotely adjustable solution, Sun has you covered with the optimization and quality your application demands.

Sun Hydro-Mechanical Cartridge Valves

The FREL is a 3-way, fully adjustable bypass/restrictive priority flow control valve that features an integral compensator which is used to regulate speed within applications regardless of pressure levels. 

The RBDA is a bi-directional, direct acting relief valve that is normally closed. Its pressure-limiting attributes allow it to protect hydraulic components from pressure transients. Due to the modulating that occurs inside of the cartridge, these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion. 

Manifold Casting

This advanced manifold casting, available exclusively on model EVY/S1, features a wealth of improvements which include optimized flow paths, reduced or eliminated number of assembled parts, as well as minimized potential leak points. This casting's design is optimized for weight reduction and offers an improved fatigue life.

Our products have stood the test of time for over half a century, and we’re even more dedicated to expanding our portfolio with the reliable solutions you've come to expect from the Sun brand.
