Import Counterbalance Valve Equivalent To Sun Cbgg — Buy in wholesale FOB from Supplier in China

The Aak Industry Co., Ltd counterbalance valve is a screw-in hydraulic component equivalent to the SUN CBGG standard part, designed to control overrunning loads in hydraulic systems. It integrates a check valve for free flow from port 2 to port 1 and a pilot-assisted relief valve to regulate flow in the reverse direction, with pilot assist at port 3 reducing the relief valve setting based on the pilot ratio. Technical parameters include a maximum operating pressure of 350 bar, a flow rate of 240 L/min, and internal leakage limited to 5 drops per minute, with a pilot ratio of 4.5:1.

Constructed with standard Buna N seals, this valve operates within a temperature range of -30 to +100 °C and is compatible with mineral-based or synthetic hydraulic fluids with lubricating properties, supporting a viscosity range of 7.4 to 420 cSt. The cavity follows the T-17A standard, and the valve is engineered for a service life twice that of domestic peers, validated by a Spain-based customer after 9 months of field testing. Typical applications include hydraulic elevators, material handling equipment, and industrial machinery requiring precise load control.

This valve is ideal for buyers in industries such as construction, manufacturing, and logistics where reliable load-holding performance is critical. Aak Industry Co., Ltd, based in Ningbo, Zhejiang, offers this product with confirmed compatibility to SUN standards, and buyers are advised to confirm packaging, lead time, and bulk trade terms directly with the supplier. The product’s benchmarking to SUN standards ensures seamless integration into existing hydraulic circuits.

Aak Industry Co., Ltd is headquartered in Bona Business Building, No. 456 Taikang Middle Road, Yinzhou District, Ningbo, Zhejiang, China. The company specializes in hydraulic components, including cartridge valves and counterbalance valves, with a focus on delivering products that meet international standards such as SUN equivalents. Their engineering team supports customization and performance benchmarking for global clients, as demonstrated by their work with a Spain-based customer who validated the CBGG equivalent valve after extensive testing.

The supplier operates within the hydraulic industry’s typical verification framework, with a trust tier classified as harbor. While their response rate is currently listed as 0.00, their technical documentation and case studies, such as the 15-month collaboration leading to the Spain order, indicate a commitment to quality and long-term customer relationships. Buyers are encouraged to request updated response metrics and verification details directly from Aak Industry Co., Ltd for the most current information.
