Sun Hydraulics is raising the bar once again with its new 0-Series counterbalance valves—available in model codes CAZA and CBZA.

“Designed for high-performance motion control, this new series packs exceptional power into a smaller, more efficient footprint, making it ideal for applications where space is tight and quality isn’t up for negotiation,” said Rick Martich, President of Sun Hydraulics & Motion Control Technology.

With its compact design, the company’s 0-Series cartridge valves maintain Sun’s industry-trusted quality, reliable load holding, and robust performance with a maximum setting of 6000 psi (420 bar). With an equal capacity of 7.5 gpm (30 L/min.), these valves are built for demanding applications that require uncompromising performance. Specific use-case examples could include mobile aerial work platforms, boom trucks, and most load holding applications.

These counterbalance valves with pilot assist allow free flow from the directional valve (port 2) to the load (port 1), while a direct-acting, pilot-assisted relief valve regulates flow from port 1 to port 2. Pilot assist at port 3 lowers the effective relief setting based on the valve’s pilot ratio, ensuring precise, responsive performance.

While both valves fit Sun’s T-163A cavity, model code CAZA features an atmospherically referenced spring chamber, allowing it to be used in applications with consistently high or dynamic back pressure on Port 2 of the counterbalance valve.

The introduction of these 0-Series valves strengthens Sun’s growing counterbalance valve product family, delivering superior load control and durability in today’s toughest hydraulic environments.
