SUN CBEA-LHN-XAW/S Counterbalance Valve – CBEA Series
Imagine a crane holding a multi-ton load mid-air, or a hydraulic press maintaining precise clamping force during a critical forming cycle — and then the control signal drops. Without a reliable counterbalance valve in the circuit, the actuator would drift, the load would descend uncontrolled, and the consequences could range from scrapped parts to catastrophic equipment failure or personnel injury. In demanding industrial environments, load-holding integrity is not optional — it is the foundation of safe, repeatable machine operation.
The SUN CBEA-LHN-XAW/S is a pilot-operated counterbalance valve from SUN Hydraulics’ industry-standard CBEA series, engineered to provide precise, stable load-holding and controlled load-lowering in hydraulic circuits. SUN Hydraulics (now Helios Technologies) is globally recognized as a benchmark manufacturer of high-performance cartridge valves, with CBEA-series counterbalance valves deployed across mobile equipment, industrial presses, offshore platforms, and factory automation systems worldwide. The CBEA-LHN-XAW/S variant is specifically configured for applications requiring external pilot actuation with a free-flow check function, making it a versatile and widely specified component in load-management circuits.

Key Features & Benefits
- Reliable Load-Holding: Prevents actuator drift under sustained load, ensuring safety in vertical and suspended-load applications.
- Pilot-Operated Design: External pilot signal enables smooth, controlled load lowering without pressure spikes or instability.
- Free-Flow Check Function: Allows unrestricted flow in the actuating direction, minimizing pressure drop during extension or lifting strokes.
- High Pilot Ratio (H): Reduces the pilot pressure required to open the valve, improving energy efficiency and response in low-pilot-pressure circuits.
- Non-Relieving (N): Maintains set pressure without venting to tank, suitable for circuits where back-pressure must be preserved.
- Cartridge Construction: Compact T-11A cavity mount simplifies manifold integration and reduces plumbing complexity.
- Nitrile Seals (/S): Compatible with standard mineral-based hydraulic oils across a wide operating temperature range.
- SUN Quality: Manufactured to SUN Hydraulics’ stringent tolerances, ensuring consistent performance and long service life.
Industry & Equipment Applications
- Mobile Hydraulics: Crane outriggers, aerial work platforms (AWPs), telehandlers, and excavator boom circuits.
- Industrial Presses: Hydraulic press platens, injection molding clamping circuits, and die-casting machines.
- Material Handling: Forklift mast circuits, dock levelers, and automated guided vehicles (AGVs).
- Offshore & Marine: Subsea actuator control, deck crane systems, and ROV hydraulic circuits.
- Factory Automation: Vertical axis servo-hydraulic systems and load-holding fixtures in assembly lines.
- Forestry & Agriculture: Log splitters, harvester heads, and tractor implement control circuits.
System Integration & Compatible Parts
The CBEA-LHN-XAW/S is designed for installation into a standard SUN T-11A cartridge cavity, compatible with SUN Hydraulics manifold blocks and third-party T-11A cavity bodies. For complete circuit design, this valve is commonly paired with:
- SUN directional control valves (DBET, DLHF series) for pilot signal generation
- SUN pressure-compensated flow controls for synchronized multi-actuator circuits
- SUN T-11A cavity manifolds (aluminum or ductile iron) for compact block integration
- Complementary CBEA variants (e.g., CBEA-LAN, CBEA-LHN) for dual-acting cylinder circuits

Frequently Asked Questions
Q: What does the “LHN” designation mean in CBEA-LHN-XAW/S?
A: “L” indicates a low crack pressure setting, “H” denotes a high pilot ratio (reducing the pilot pressure needed to open the valve), and “N” means non-relieving — the valve does not vent excess pressure to tank.
Q: What cavity does the CBEA-LHN-XAW/S use?
A: It uses the standard SUN T-11A cartridge cavity, which is widely available in SUN manifold blocks and compatible third-party bodies.
Q: Can this valve be used in a dual-acting cylinder circuit?
A: Yes, for dual-acting cylinders, two counterbalance valves are typically used — one on each actuator port. Contact us for circuit design guidance.
Q: What hydraulic fluid is compatible with the /S (Buna-N) seal option?
A: Buna-N seals are compatible with standard mineral-based hydraulic oils (ISO VG 32–68). For phosphate ester or water-glycol fluids, alternative seal materials are required — contact us for the appropriate variant.
Q: Do you provide datasheets or technical documentation?
A: Yes. Official SUN Hydraulics datasheets are available upon request. Contact support@konmask.com with your inquiry.
Q: What is the minimum order quantity (MOQ)?
A: We accommodate single-unit orders for MRO and replacement needs, as well as bulk orders for OEM and project procurement. No strict MOQ — contact us to discuss your requirements.
