Helios Technologies’ Sun Hydraulics Launches 0‑Series Counterbalance Valves for High‑Performance Mobile Applications

Sun Hydraulics, a subsidiary of Helios Technologies, today introduced its 0‑Series counterbalance valves, a new line of high‑pressure, high‑flow valves engineered for mobile hydraulic applications such as aerial work platforms, boom trucks, and load‑holding equipment. The 0‑Series, available in CAZA and CBZA models, delivers a maximum pressure of 6,000 psi (420 bar) and a flow capacity of 7.5 gpm (30 L/min), enabling operators to maintain precise control in demanding, space‑constrained environments.

The valves incorporate Sun Hydraulics’ floating‑nose cartridge technology, which reduces internal volume while maintaining structural integrity at extreme pressures. Pilot‑assist technology allows free flow from the directional valve to the load, while a direct‑acting, pilot‑assisted relief valve regulates reverse flow, providing responsive performance under dynamic pressure conditions. The compact footprint and robust design position the 0‑Series as a differentiated offering against larger, less efficient competitors in the high‑pressure counterbalance market.

Helios’ strategy has long focused on niche hydraulic markets where high‑margin products can drive growth. CEO Rick Martich said the 0‑Series “delivers maximum power in a compact footprint, meeting the demanding needs of mobile hydraulic applications.” The launch expands Sun Hydraulics’ reach into mobile sectors that require both space efficiency and reliability, aligning with Helios’ broader goal of capturing high‑margin opportunities through innovative valve technology.

The introduction of the 0‑Series is expected to strengthen Sun Hydraulics’ position in the mobile hydraulic market, potentially increasing revenue from high‑pressure applications and reinforcing Helios’ reputation for engineering excellence. By offering a more compact, high‑performance solution, the company can capture market share from established players and support its long‑term growth strategy in differentiated product lines.
