JCB COUNTER BALANCE CHECK VALVE P/N 25/222920
This counter balance check valve (part no.: 25/222920) is designed for JCB equipment (including backhoes, loaders) and other compatible hydraulic systems, produced by Ningbo Longerfa Hydraulic Co., Ltd.—a professional manufacturer of JCB-matching hydraulic parts (balance valves, check valves, etc.).
Longerfa holds ISO9001 and ISO45001 certifications, and relevant patents for hydraulic valve technology. Each 25/222920 valve undergoes strict quality testing, meeting original equipment standards to ensure compatibility with applicable JCB and compatible hydraulic systems.
As a core component of the hydraulic circuit, its main functions include: preventing sudden load dropping (e.g., for loader buckets, backhoe arms) and controlling one-way oil flow. It maintains stable pressure during load lifting and lowering to protect hydraulic cylinders and pipelines.
The valve adopts a wear-resistant spool and corrosion-resistant valve body. It supports direct bolt-on replacement without additional system debugging, helping reduce maintenance time. It is commonly used in construction, agricultural, and municipal engineering scenarios.
Longerfa’s 25/222920 valve ensures stable load control for applicable equipment and works reliably in harsh operating environments.
